The present disclosure relates to the field of skincare, and in particular to shaving. More specifically, the present disclosure relates to multi-piece handle assemblies. 
    
    
     FIELD 
     When shaving using a razor, user comfort and ease of manipulation may depend on factors such as the weight and shape of the shaver. Some known razors comprise handles formed by several parts assembled together, made by more than one materials, which cannot be easily disassembled after the manufacturing process. Documents US20180043553 and U.S. Pat. No. 6,749,788 disclose such razors. 
     SUMMARY 
     It may be desirable to provide a handle which is simple to use on its own in the safe manipulation of a skincare head e.g. exfoliation and/or shaving head, but which can also support one or more additional items detachable therefrom and/or removably attached thereto. The handle and additional items(s) may form a handle assembly in which the additional items are disassemblable from the handle. 
     According to examples, a handle assembly may be provided. The handle assembly is for a hair removal device. The handle comprises a handle. The handle includes a connection portion for supporting a hair removal head and an elongated grip portion extending therefrom. The handle assembly comprises at least a first accessory component. The first accessory component is disassemblable from the grip portion. The handle assembly comprises a holding mechanism. A first portion of the holding mechanism is engageable with a second portion of the holding mechanism to resist disassembly of the first accessory component from the grip portion. 
     The holding mechanism includes a first magnetic element and a second magnetic element that is positioned relative to the first magnetic element when the holding mechanism is engaged so that the first and second magnetic elements cooperatively resist disassembly of the first accessory component from the grip portion. 
     The first accessory component may have a higher overall mass and/or a higher overall density than the grip portion. 
     The grip portion may comprise a first material. The first accessory component may comprise a second material, different from the first material. 
     The first accessory component may comprise an outer surface. The outer surface may be contactable by an appendage of a user when the accessory component is assembled to the grip portion. The outer surface may comprise at least one of the following: a depression for receiving at least a portion of the appendage, a protrusion for engaging a concave region of the appendage, and/or a gripping feature. The appendage is for example a palm of the user&#39;s hand or a finger of the user&#39;s hand, or any other portion of the user&#39;s body manipulating the handle. 
     The holding mechanism may include a press fit that is engageable to resist disassembly of the first accessory component from the grip portion. 
     The holding mechanism may include a snap fit that is engageable to resist disassembly of the first accessory component from the grip portion. 
     The first magnetic element may comprise a first magnet. The first magnetic element may be located in the first portion of the holding mechanism, and the second magnetic element may be located in the second portion of the holding mechanism, or vice versa. 
     The second magnetic element may comprise a second magnet. 
     The grip portion may comprise a recess in which the first accessory component is receivable. 
     The grip portion may include a through-hole at the recess. 
     The first accessory component may comprise the first portion of the holding mechanism. 
     The handle assembly may comprise at least a second accessory component. The second accessory component may be disassemblable from the grip portion. 
     The second accessory component may be configured to couple to the first accessory component. 
     The second accessory component may comprise the second portion of the holding mechanism. 
     A handle assembly as described herein may offer users enhanced customization options because its handle may be suitable for use as a razor handle even when accessory components are detached therefrom. The user may easily play with the different accessory components to e.g. add/reduce weight of the handle assembly or to change the accessory to select different accessory components which may incorporate a different outer surface thereby changing user&#39;s touch experience. Additionally, a handle assembly as disclosed herein may be recycled with ease, owing to the accessory component/components being separable from the handle. 
     According to examples, a process of recycling may be provided for a handle as disclosed herein. The recycling process comprises disassembling at least one accessory component from a grip portion of a handle, followed by recycling the grip portion and/or the accessory component. 
     According to embodiments of the present disclosure, the process may comprise recycling the grip portion according to a first recycling process, and recycling the accessory component according to a second recycling process, different from the first recycling process. 
     According to examples, a kit comprising the handle assembly substantially as disclosed herein and a plurality of accessory components substantially as disclosed herein may be provided. The plurality of accessory components may comprise different materials or the same material. This provides for a customizing option to the user and a more personalized product.

     DETAILED DESCRIPTION 
     As used in this disclosure and the appended claims, the singular forms “a”, “an”, and “the” include plural referents unless the content clearly dictates otherwise. As used in this disclosure and the appended claims, the term “or” is generally employed in its sense including “and/or” unless the content clearly dictates otherwise. 
     The following detailed description should be read with reference to the drawings. The detailed description and the drawings, which are not necessarily to scale, depict illustrative aspects and are not intended to limit the scope of the disclosure. The illustrative aspects depicted are intended only as exemplary. 
       FIG. 1A  shows a hair removal device, for example a razor, including a handle assembly  20  as described herein, with which a user may be able to manipulate the hair removal device. 
     The handle assembly  20  comprises a handle  40 . The handle  40  includes a connection portion  42  for supporting e.g. a hair removal head, such as a shaver head, for example a razor cartridge  44 . 
     The handle assembly  20  comprises at least a first accessory component  100 A. For example, as seen in  FIG. 1A , the handle assembly  20  may comprise a first accessory component  100 A and a second accessory component  100 B. 
     At least one of the accessory components may be assemblable to the handle  40 . For example, as seen in  FIG. 1A , both the first accessory component  100 A and second accessory  100 B component are assemblable to the handle  40 . 
     Additionally or alternatively, when multiple accessory components are present, two or more of the accessory components may be structurally analogous to one another, except as necessary for possible cooperation with one another. For example, as seen in  FIG. 1B , the first  100 A and second  1008  accessory components are substantially mirror images of each other, except as necessary for them to couple to each other. Accordingly, analogous features on the first and second accessory components share reference numbers and are differentiated from each other by use of the letters A and B, respectively. 
     The coupling of multiple accessory components to one another may occur when and/or as at least two of them are assembled to the handle  40 . For example, in  FIG. 1A , assembling both of the first  100 A and second  100 B accessory components to the handle  40  also causes the first  100 A and second  100 B accessory components to couple to each other. The first and second accessory components  100 A,  100 B may have different surface textures and/or colors. 
     Additionally, the hair removal device may be provided as a kit comprising a handle, a head, and a plurality of accessory components. That accessory components may have different features that may be used by the user according to his/her desire. 
     The handle  40  includes an elongated grip portion  50  extending from the connection portion  42 . The handle of the handle assembly as disclosed herein may be suitable for manipulation of the hair removal device, even when the handle is not connected to any accessory component. As such, the handle assembly as disclosed herein may offer a wide range of customization options. 
     The length of the grip portion  50 , in the absence of any accessory component assembled thereto, may be sufficient for safe manipulation by a human hand, and may be sufficient for the hand to close there around. 
     The grip portion  50  may, for example, have a length of 80-150 mm. The length may be measured along a length axis L running between the connection portion  42  of the handle  40  and a free extremity  51  of the grip portion  50 , located opposite the connection portion  42 . The grip portion may have a width (as measured perpendicular to the length) of 6-25 mm. 
     At least one accessory component may be arranged laterally with respect to the handle  40  or grip portion  50  thereof. For example, as seen in  FIG. 1A , assembly of the first accessory component  100 A and/or the second accessory component  100 B to the handle  40  or grip portion  50  may allow the handle assembly  20  to have a greater girth than the handle  40  alone. 
     Additionally or alternatively, at least one accessory component may be arranged to extend beyond the free extremity  51  of the grip portion  50 . For example, as seen in  FIG. 1A , assembly of the first accessory component  100 A and/or the second accessory component  1008  to the handle  40  or grip portion  50  may allow the handle assembly  20  to have a greater length than the handle  40  alone. 
     At least one of accessory component may be disassemblable from the handle. For example, in  FIG. 1B , the handle assembly  20  of  FIG. 1A  is shown, in which the first accessory component  100 A is disassembled from the handle  40 . 
     When multiple accessory components are present, at least two of them may be disassemblable from the handle. For example, in  FIG. 1B  the first  100 A and second  100 B accessory components are both disassemblable from the handle  40 . 
     In examples, when multiple accessory components are coupleable to one another, they may be decoupleable from one another when and/or as at least one of them is disassembled from the handle. For example, in  FIG. 1B , disassembling the first accessory component  100 A from the handle may also cause it to decouple from the second accessory component  100 B, and/or vice versa. 
     The handle assembly comprises a holding mechanism, of which a first portion is engageable with a second portion to resist disassembly of at least one accessory component from the handle or grip portion thereof. For example, in  FIG. 1B , a first portion  170 A is provided on the first accessory component  100 A, and is engageable with a second portion  70 A that is provided on the grip portion  50  to resist disassembly of the first accessory component  100 A from the handle  40 . 
     When multiple accessory components are present, a first of the multiple accessory components may be provided with a first portion of a first holding mechanism, corresponding to a second portion of the first holding mechanism provided on the handle and engageable therewith, and a second of the multiple accessory components may be provided with a first portion of a second holding mechanism, corresponding to a second portion of the second holding mechanism provided on the handle and engageable therewith. For example, in  FIG. 1B , the second accessory component  1008  and the grip portion  50  are respectively provided with first  170 B and second  70 B portions of a holding mechanism, which are analogous to the first portion  170 A provided on the first accessory component  100 A and to the second portion  70 A engageable therewith provided on the grip portion  50 , respectively. 
     Additionally or alternatively, when multiple accessory components are coupleable to one another, the holding mechanism may be provided so as to resist decoupling of the accessory components from one another. For example, in  FIG. 1B , a first portion  180 A of the holding mechanism is provided on the first accessory component  100 A, and is engageable with a second portion  180 B of the holding mechanism that is provided on the second accessory component  1008 . 
     When multiple accessory components are each assembled to the handle and coupled to each other, resistance of decoupling of the accessory components from each other may serve to resist disassembly of at least one of the accessory components from the handle. For example, as seen in  FIGS. 1A-1B , disassembly of the first accessory component  100 A from the handle  40  (or the second accessory  100 B component from the handle  40 ) may also cause decoupling of the first  100 A and second  100 B accessory components from each other. Thus, a holding mechanism that is engageable to resist decoupling of the first and second accessory components from each other may also be able to resist disassembly of the first and/or second accessory component from the handle and this can be done, in examples, without any further coupling elements provided on the handle nor on the gripping portion of the handle. 
     As a nonlimiting example, at least one first portion of the holding mechanism may comprise one or more female features, and the corresponding second portion(s) of the holding mechanism may comprise a corresponding number of male features, or vice versa. For example, in  FIG. 1B , the first accessory component  100 A comprises a female feature (groove  172 A, analogous to groove  172 B visible on second accessory component  100 B), and the grip portion  50  comprises a male feature (ridge  72 A) receivable in the female feature when the holding mechanism is engaged. Additionally or alternatively, as seen in  FIG. 1B , for example the grip portion  50  may comprise a female feature (recess  74 A), and the first accessory component  100 A may comprise a male feature (protuberance  174 A, analogous to protuberance  1748  on second accessory component  100 B), receivable in the female feature when the holding mechanism is engaged. Moreover, the first portion of the holding mechanism may even comprise a mixture of male and female features, and the second portion of the holding mechanism engageable therewith may comprise a corresponding mixture of male and female features. For example, in  FIG. 1B , the first portion  170 A of the holding mechanism comprises a groove  172 A (female) in combination with a protuberance  174 A (male), both of which are more clearly represented as groove  172 B and protuberance  1746  on second accessory component  1008 , and the second portion  70 A of the holding mechanism comprises a ridge  72 A (male) in combination with a recess  74 A (female). 
     In  FIG. 16 , the first accessory component  100 A comprises one or more projections  182 A,  182 ′A, and the second accessory component  100 B comprises a corresponding number of indentations  183 B,  183 ′B configured to receive the projections therein when the holding mechanism is engaged. Although  FIG. 1B  shows all projections  182 A,  182 ′A as being provided on the first portion  180 A of the holding mechanism, and all of the indentations  183 B,  183 ′B as being provided on the second portion  180 B of the holding mechanism, it is equally foreseen to provide one or more projections in combination with one or more indentations on the first portion  180 A of the holding mechanism, and a corresponding combination on the second portion  180 B of the holding mechanism. As seen in  FIG. 16 , when multiple projections and indentations are provided, at least one projection and its corresponding indentation may have a different size or shape from the other projection(s) and indentation(s), so as to serve a keying function between the first  180 A and second  180 B portions of the holding mechanism. 
     The use of one or more corresponding projections and indentations is not limited to being provided as a way of resisting decoupling of the accessory components from one another. Rather, it is foreseen as a variant to use these structures as an alternative to or in combination with the corresponding ridge(s) and groove(s), and/or as an alternative to or in combination with the corresponding recess(es) and protuberance(s) to resist disassembly of at least one accessory component from the grip portion. Likewise, the corresponding groove(s) and ridge(s), and/or the corresponding recess(es) and protuberance(s) may be used as an alternative to or in combination with the corresponding projections(s) and indentation(s) to resist decoupling of the accessory components from one another. Moreover, although the corresponding groove(s) and ridge(s) are shown in  FIG. 1B  as being used in combination with the corresponding recess(es) and protuberance(s), these corresponding features may, as a nonlimiting example, be used independently of each other. 
     The holding mechanism may include a press fit and/or a snap fit that is engageable to resist disassembly of at least one accessory component from the grip portion. For example, as seen in  FIG. 1B , engaging the holding mechanism may cause the ridge(s)  74 A,  74 B to snap fit and/or press fit into the groove(s)  174 A,  174 B. Additionally or alternatively, engaging the holding mechanism may cause one or more projections  182 A,  182 ′A to snap fit and/or press fit into the corresponding indentation(s)  183 B,  183 ′B, for example. Additionally or alternatively, engaging the holding mechanism may cause the protuberance(s)  174 A,  1748  to snap fit and/or press fit into the recess(es)  74 A,  74 B, for example. 
     The holding mechanism comprises two or more magnetic elements, of which a first magnetic element may comprise a first magnet, and of which a second magnetic element is positioned relative to the first magnetic element when the holding mechanism is engaged so that the first and second magnetic elements cooperatively resist disassembly of at least one accessory component from the handle or grip portion thereof. As a nonlimiting example, the first magnetic element may be provided in the first portion of the holding mechanism, and the second magnetic element may be provided in the second portion of the holding mechanism engageable therewith, or vice versa. 
     For example, as seen in  FIG. 1B , the first magnetic element  10  may be provided in the handle  40  or the grip portion  50  thereof. The first accessory component  100 A may comprise the second magnetic element  12 A, for example. The inverse is also foreseen. When the first accessory component  100 A is assembled to the handle  40 , the first  10  and second  12 A magnetic elements engage each other magnetically, allowing them to cooperatively resist disassembly of the first accessory component  100 A from the handle  40  or grip portion  50  thereof. According to an example, also represented in  FIG. 1B , the second accessory component  1006  may also comprise an equivalent magnetic element  12 B to that which is provided on the first accessory component, such that the magnetic element  10  provided on the handle  40  cooperatively resists disassembly of each of these accessory components  100 A,  100 B from the handle  40  or grip portion  50 . 
     As explained earlier, when multiple accessory components are coupled to one another, a holding mechanism that is engageable to resist decoupling of the accessory components from one another can also have the effect of preventing disassembly of at least one of the accessory components from the handle. As seen in  FIG. 1B , the first accessory component  100 A from may include a first magnetic element  11 A, and the second accessory component  100 B may include a second magnetic element  22 B engageable therewith to cooperatively resist decoupling of the first  100 A and second  100 B accessory components from one another. 
     The holding mechanism may comprise magnetic elements independently of whether it comprises male and female parts, or as seen in  FIG. 1B  magnetic elements  10 ,  11 A,  12 A,  12 B,  22 B may be used in combination with female and male parts. For example, magnetic elements  10 ,  12 A arranged in the recess  74 A of the handle and on the protuberance  174 A of the accessory component  100 A are engageable with one another, and magnetic elements  11 A,  22 B arranged in at least one of the projections  180 A and at least one of the indentations  180 B are engageable with one another. 
     According to examples, the second magnetic element may comprise a second magnet. In examples, the second magnetic element may simply comprise a magnetic material, such as iron, steel, cobalt etc. or any other Ferromagnetic materials, which, in  1   s  response to an applied magnetic field having a first polarity, is able to produce a magnetic field of an opposite polarity to the first polarity. 
     According to examples, at least one accessory may be made of a magnetic material. For example, the first accessory component (or the second accessory component, when present) may be made of a magnetic material. In this regard, the accessory component may be considered to be or comprise the second magnetic element. 
     The first and second magnetic elements may resist disassembly, be it disassembly of the first accessory component (or second accessory component, when present) from the handle or grip portion thereof, or by resisting decoupling of the first and second accessory components from one another, through magnetic attraction, or magnetic repulsion. For example, magnetic repulsion may be suitable for resisting disassembly when disassembly causes the first and second magnetic elements to pass by one another, whereas magnetic attraction may be suitable for resisting disassembly when disassembly does not cause the first and second magnetic elements to pass by one another. 
     For example, in the holding mechanism shown in  FIG. 1B  for resisting decoupling of the first accessory component  100 A and second accessory component  100 B from each other, a magnetic field having a first polarity may be provided at a free extremity of a projection  182 A of first portion  180 A of the holding mechanism to extend towards a corresponding indentation  183 B of the second portion  1808  of the holding mechanism. In order to resist disassembly through magnetic attraction when the holding mechanism is engaged, a magnetic field having an opposite polarity to the first polarity may be provided at a closed extremity of the indentation  183 B to extend towards the projection  182 A. When the free extremity of the projection  182 A is inserted in the indentation  183 B, magnetic fields attract the first  11 A and second  22 B magnetic elements to one another, and thus may resist disassembly. Such a configuration may be suitable whether the second magnetic element  22 B merely comprises the magnetic material or whether the second magnet is present (and arranged to produce the field having the opposite polarity). 
     In order to resist disassembly through magnetic repulsion when the holding mechanism is engaged, the first magnetic element  11 A may be positioned at the free extremity of the projection  182 A such that the magnetic field it produces extends towards a fixed extremity of the projection  182 A with a first polarity, and the second magnetic element  22 B (which in this configuration comprises the second magnet) may be positioned at an open extremity of the corresponding indentation  183 B and arranged to produce a field having a same polarity as the first polarity extending towards the closed extremity. When the free extremity of the projection  182 A is intermediate the open and closed extremities of the indentation  183 B, the magnetic fields of the first  11 A and second  22 B magnetic elements repel one another, and thus may resist decoupling. 
     At least one accessory component may have a higher overall mass and/or a higher overall density than the handle, and/or it may have a higher overall mass and/or a higher overall density than grip portion. For example, as seen in  FIG. 1B , the grip portion  50  may comprise a first material, and the first accessory component  100 A may comprise a second material, different from the first material. 
     For example, the grip portion  50  may comprise one or more of the following materials: M-ABS, MBS, Polycarbonate, PET, Copolyester, Polypropylene (including reinforced polypropylene), ABS, HIPS, PC/ABS, PC/PET, Polyacetal, PPE/PS, PLA compound, Polystyrene (GPPS), Polyethylene, Polyamide, Pre-Post-consumer recycled plastic, which may be well-suited for molding. Additionally or alternatively, the grip portion may comprise thermoplastic filaments (e.g. ABS, PLA, nylon, PETG), thermoplastic powders (e.g. polyamide 12, polyamide 11), thermoset photopolymer resins (e.g. standard, ABS-like, PP-like, rubber-like, high temperature) or thermoset liquid resins (e.g. standard, ABS-like, PP-like, rubber-like, high temperature), which may be well-suited for additive manufacturing processes. For example, the first accessory component may comprise any of the materials listed with regards to the grip portion, or, for example one or more of the following materials: M-ABS, MBS, polycarbonate, PET, copolyester, polypropylene, ABS, HIPS, PC/ABS, PC/PET, polyacetal, PPE/PS, thermoplastic filaments (e.g. ABS, Nylon), thermoplastic powders (e.g. polyamide 12, polyamide 11), thermoset photopolymer resins (e.g. ABS-like, PP-like), or thermoset liquid resins (e.g. ABS-like, PP-like). The first accessory component  100 A may additionally or alternatively comprise a metal (e.g. Zamak, Aluminum), which may be well-suited for molding or Titanium, Stainless Steel, Cobalt chrome or Nickel which may be well-suited for additive manufacturing processes. For example, as explained earlier, it is foreseen for at least a portion of the first accessory component to comprise a magnetic element, which may include a metal material. The second accessory component  100 B (when present) may be made of the same material(s) as the first accessory component  100 A, or of different materials from the first accessory component  100 A. 
     At least one accessory component may comprise an outer surface that is contactable by an appendage of a user when the accessory component is assembled to the grip portion. For example, the outer surface may be contactable by a user&#39;s hand. In  FIG. 1B , for example, both the first accessory component  100 A and the second accessory component  1008  present such surfaces  121 A,  121 B. 
     The outer surface may provide one or more ergonomic features to the handle assembly. For example, the outer surface may provide at least one of the following: gripping feature, a protrusion for engaging a concave region of the appendage (for example a palm of the user&#39;s hand), and a depression for receiving at least a portion the appendage (for example a finger of the user&#39;s hand). A gripping feature  122 A,  122 B is represented in  FIG. 1B , for example. 
     The gripping feature may provide a higher coefficient of friction against a user&#39;s skin than the remainder of the outer surface. This coefficient of friction may be provided, for example, through the use of a textured surface and/or a material such as a rubber. For example, the rubber may be an elastomeric or a thermoplastic elastomeric (TPE) material. The rubber may have a hardness of approximately 15-70 Shore A. The gripping feature may include, but are not limited to silicones, natural rubber, butyl rubber, styrene butadiene rubber, polyolefin-based TPEs, styrene butadiene styrene (SBS) TPEs, styrene ethylene butadiene styrene (SEBS) TPEs, polyamide TPEs (such as Pebax), polyester TPEs, or polyurethane TPEs. The gripping feature may indude a blend of one or more of these TPEs with other substances. The gripping feature may include a blend of multiple of these TPEs, possibly in combination other substances. 
     According to examples of the present disclosure, the gripping feature may be provided in combination with at least one other ergonomic feature. For example, in  FIG. 1B , the gripping feature  122 A of the first accessory component  100 A is provided in combination with a protrusion  124 A presented on the same outer surface  121 A as one another. The same is also visible for the second accessory component  100 B with the protrusion  1246 . The protrusion  124 A and/or  124 B may engage the palm of the user&#39;s hand, for example. 
     As seen  FIG. 16 , the ergonomic feature(s) may be provided on an insert  119 A received in the outer surface  121 A of the first accessory component  100 A. The same may additionally or alternatively be true for the second accessory component  100 B, when present. 
     Use of an insert  119 A,  1196  to provide the ergonomic feature(s) may enhance recyclability, such as by allowing items materials which cannot be converted back into raw materials through a common process, (as with metal and plastic, for example) to be separated and processed independently from one another. 
     According to examples, the grip portion  50  may include a through-hole. Use of a through hole may offer weight and/or material reductions in the grip portion. As seen in  FIG. 16 , for example, the through-hole  52  may be provided in the recess  74 A. 
       FIG. 2  shows a handheld device including a variant  220  of the handle assembly  20  shown in  FIG. 1B . 
     As with the accessory components  100 A,  1006  shown in  FIG. 16 , at least one of the accessory components  300 A,  3006  shown in  FIG. 2  may have a higher overall mass and/or density than the handle  240  and/or the grip portion  250  thereof. Additionally or alternatively, at least one of the accessory components  300 A,  3006  shown in  FIG. 2  may comprise a different material from the grip portion  250 . 
     As seen in  FIG. 2 , at least one accessory component  300 A,  3006  may comprise a depression  126 A provided on an outer surface  321 A of the accessory component. A depression is a nonlimiting example of an ergonomic feature, which is also compatible with a handle assembly substantially as represented in  FIG. 1B . 
     At least one gripping feature  122 A may be provided in a handle assembly  220  as shown in  FIG. 2 . For example, the gripping feature(s) may be provided on one or more accessory components  300 A,  3006  of the handle assembly  220  as shown in  FIG. 2 . Such a gripping feature may be used in combination with a depression  126 A, or independently therefrom. 
     In  FIG. 2 , for example, ergonomic features are provided directly on the accessory component  300 A,  3006 , rather than on inserts as seen in  FIG. 1B . However, it is equally foreseen to provide at least one insert for the at least one accessory component of the handle assembly  220  illustrated in  FIG. 2 . Generally speaking, provision of multiple ergonomic features (such as a gripping feature on a protrusion or on a depression, for example) is also possible when the ergonomic features are provided directly on the outer surface of an accessory component. 
     Although, as seen in  FIG. 1B  it is foreseen to provide accessory components  100 A,  100 B which attach to the handle  40  and/or which couple to each other around the handle  40 , it is also foreseen for accessory components to couple to each other through the handle. For example, as seen in  FIG. 2 , the first accessory component  300 A couples to the second accessory component  300 B through the handle  240 . To that end, as seen in  FIG. 2 , the handle  240  may be provided with a through hole  252 ,  253  through which the first  300 A and second  300 B accessory components are able to couple to one another. The through-hole  252 ,  253  may serve to align and/or stabilize the coupled accessory components, such as through contact within the through-hole. In examples, it is also foreseen, though not shown in these figures, that at least one of the accessory components may additionally be press-fit or snap-fit into its respective through-hole, so as to further resist disassembly of the accessory component from the handle. 
     In  FIG. 2 , a holding mechanism is provided to resist decoupling of the first  300 A and second  300 B accessory components from each other. For example a first accessory component  300 A may comprise a first portion  480 A of the holding mechanism, and a second accessory component  300 B, coupleable to the first accessory component  100 A, may comprise a second portion  480 B of the holding mechanism, or vice versa. 
     At least one portion of the holding mechanism may be provided on a post extending from one of the accessory components towards another of the accessory components coupleable therewith. For example, as seen in  FIG. 2 , the first portion  480 A of the holding mechanism is arranged on a post  490 A extending from one of the first  300 A and second  300 B accessory components (which are configured to couple to one another) and the second portion of the holding mechanism  480 B is provided on the other of the first and second accessory components. 
     As a nonlimiting example, as seen in  FIG. 2 , the first accessory component  300 A may comprise a post  490 A extending towards the second accessory component  3008 , and the second accessory component  300 B may comprise a post  490 B extending towards the first accessory component  300 A, and the first  480 A and second  480 B portions of the holding mechanism may be provided on these posts respectively, or vice versa. 
     As seen in  FIG. 2 , for example, the posts  490 A,  4908  of the first  300 A and second  300 B accessory components may be substantially equal in length to one another. However, it is also foreseen to provide posts of unequal length within a group of accessory components that are configured to couple to one another. 
     The first portion  480 A of the holding mechanism may comprise a bulb  482 A, and the second portion  480 B of the holding mechanism may comprise a corresponding socket  483 B into which the bulb  482 A is snap-fittable. As seen in  FIG. 2 , the holding mechanism may comprise multiple such bulbs, and a corresponding number of such sockets. As seen in  FIG. 2 , at least one bulb and/or socket may be borne on a free extremity of a post extending from an accessory component. 
     Although  FIG. 2  shows the first portion  480 A of the holding mechanism as comprising only bulbs  482 A, and the second portion  480 B of the holding mechanism as comprising only sockets  483 B, it is also foreseen for the first portion  480 A of the holding mechanism to comprise one or more bulbs in combination with one or more sockets, and for the second portion  4808  of the holding mechanism to comprise corresponding numbers of sockets and bulbs. 
     At least one of the accessory components may be provided as a plurality of bodies. For example, in  FIG. 2 , the first accessory component  300 A includes a first body  310 A and a second body  360 A. 
     As seen in  FIG. 2 , the first body  310 A may present a depression  126 A, and the second body  360 A may present a protrusion  124 A. It is also foreseen, though not illustrated, that multiple bodies within a given accessory component present similar ergonomic features to one another. 
     The holding portion of the mechanism provided on a given accessory component may be arranged on each of these bodies. For example, in  FIG. 2 , the holding mechanism is arranged posts  490 A,  492 A,  494 A, extending from each of the first  310 A and second  360 A bodies. Although the posts  490 A,  492 A,  494 A extending from these bodies  310 A,  360 A are represented in  FIG. 2  as having substantially equal length to one another, it also foreseen that at least post on the first body  310 A has a different length from at least one post on the second body  360 A. 
     As seen in  FIG. 2 , the holding mechanism may be arranged on a single post  490 A extending from the first body  310 A, and a plurality of posts  492 A,  494 A extending from the second body  360 A. Although the first  310 A and second  360 A bodies are shown in  FIG. 2  is having dissimilar quantities of posts, it also is foreseen for the bodies of a given accessory component to have a like number of posts. 
     Although  FIG. 2  shows the plurality  492 A,  494 A of posts of a given body is having substantially equivalent lengths to one another, it is equally foreseen that the posts of a given body have unequal lengths to one another. 
     As seen in  FIG. 2 , for example, the first body  310 A of an accessory component may be arranged near the connection portion  242  of the handle  240 , and the second body  360 A of the accessory component may be arranged near the free extremity  251  of the grip portion  250 . An inverse configuration to this is also foreseen. 
     Although  FIG. 2  shows the bodies  310 A,  360 A of the first accessory component  300 A as being arranged in series along a length axis L of the handle  240  or grip portion  250  thereof, other arrangements are also foreseen, including (but not limited to) circumferential and/or helical arrangements about the length axis L. 
     As seen in  FIG. 2 , the grip portion  250  may comprise a first through-hole  252  and a second through-hole  253 . The first body  310 A of the first accessory component  300 A may be coupleable with the second accessory component  300 B through the first through-hole  252 , and the second body  360 A of the first accessory component  300 A may be coupleable with the second accessory component  300 B through the second through-hole  253 , or vice-versa. At least one of these through-holes may help to align and/or stabilize the corresponding body therein, for example through contact between the body and the through-hole. 
     As seen in  FIG. 2 , the second accessory component  300 B may also comprise a plurality of bodies  3108 ,  360 B. When both first  300 A and second  300 B accessory components comprise multiple bodies  310 A,  360 A,  3108 ,  360 B, at least one body  3108 ,  360 B of the second accessory component  300 B may be stabilized and/or aligned by means of a through-hole  252 ,  253  through which it is coupleable to the first accessory component  300 A. When one or more ergonomic features are provided on at least one body of the second accessory component  300 B, the ergonomic feature(s) may be selected independently of whatever ergonomic features may be provided on the first accessory component  300 A. 
     Although  FIG. 2  shows the second accessory component  300 B (to which the first accessory component  300 A is coupleable) as comprising a corresponding plurality of bodies  310 B,  360 B which are each analogous to the bodies  310 A,  310 B of the first accessory component  300 A, it is also foreseen for an accessory component comprising multiple bodies to be coupleable with a one-piece accessory component. Moreover, it is also foreseen that, when the second accessory component comprises multiple bodies, that these bodies be non-analogous to the bodies of the first accessory component. 
       FIG. 3  shows a handheld device including a variant  520  of the handle assembly  220  shown in  FIG. 2 . To resist decoupling of the first  600 A and second  600 B accessory components from one another, the first  780 A and second  780 B portions of the holding mechanism comprise a first magnetic element  11 A (including a first magnet) and a second magnetic element  22 B, respectively, or vice versa. When the first  600 A and second  600 B accessory components are assembled to the handle  240 , the first  780 A and second  780 B portions of the holding mechanism (and the magnetic elements  11 A,  22 B respectively comprised thereby) are brought sufficiently close to one another that their respective magnetic elements magnetically engage one another so as to couple the first and second accessory components to each other. This magnetic engagement causes the first  780 A and second  780 B portions of the holding mechanism to cooperatively resist decoupling of the first  600 A and second  6008  accessory components from each other. 
     As seen in  FIG. 3 , the first  11 A and second  22 B magnetic elements may be arranged in a substantially similar manner to the bulb(s)  482 A and socket(s)  483 B shown in  FIG. 2 . 
     For example, at least one of the first and second magnetic elements may be provided at a free extremity of a post extending from the first accessory component towards the second accessory component. As seen in  FIG. 3 , the first  11 A and second  22 B magnetic elements may be provided at free extremities of corresponding posts  790 A,  790 B,  792 A,  792 B,  794 A,  7946  extending respectively from the first  600 A and second  600 B accessory components, or vice versa. 
     As seen in  FIG. 3 , the post(s)  790 A,  790 B,  792 A,  792 B,  794 A,  7948  may have sufficient length to bring the first magnetic element(s)  11 A into contact with the second accessory component  600 B. As a nonlimiting example, the first magnetic element(s)  11 A may contact the second magnetic element(s)  22 B directly. 
     However, it is also foreseen that at least one first magnetic element  11 A be made to magnetically engage a corresponding second magnetic element  22 B without contacting it directly. For example, the post(s) may be arranged between the first  11 A and second  22 B magnetic elements. 
     Moreover, it is also foreseen that at least one first magnetic element  11 A be made to magnetically engage a corresponding second magnetic element  22 B without direct contact between the first  600 A and second  600 B accessory components. For example, the length(s) of the post(s)  790 A,  790 B,  792 A,  792 B,  794 A,  7948  may be insufficient for contact between the first  600 A and second  600 B accessory components, or the post(s) may even be absent. 
     When an accessory component comprises multiple bodies, the portion of the holding mechanism provided on the accessory body may be provided on each of these bodies. 
     For example, a magnetic element may be provided on each of the bodies  610 A,  660 A of the first accessory component  600 A, and these magnetic elements may be magnetically engageable with one or more magnetic elements provided on the second accessory component  600 B. 
     As seen in  FIG. 3 , for example, the first bodies  610 A,  610 B of the first  600 A and second  600 B accessory components are provided with a pair of magnetic elements, of which at least the first magnetic element  11 A comprises a magnet. As a nonlimiting example, the first  11 A and second  22 B magnetic elements of the pair may be provided in corresponding free extremities of posts  790 A,  790 B extending from the first bodies  610 A,  610 B of either accessory component  600 A,  600 B. 
     According to an example, and independently of the manner in which the first bodies  610 A,  610 B couple to one another, the second bodies  660 A,  660 B of the first  600 A and second  600 B accessory components may be provided with a pair of magnetic elements  11 A,  22 B, in a similar manner to that which is described above with regard to the first bodies  610 A,  610 B. 
     As seen in  FIG. 3 , for example, the second bodies  660 A,  660 B of the first  600 A and second  600 B accessory components may be provided with four magnetic elements  11 A,  22 B,  11 B,  22 A, which are engageable with one another in two pairs, with each pair having at least one magnet. 
       FIG. 4  shows a handheld device including a variant  820  of the handle assembly  220  shown in  FIG. 2 . To resist decoupling of the first  900 A and second  900 B accessory components from one another, the first  1080 A and second  1080 B portions of the holding mechanism comprise a rod  1082 A and a cavity  1083 B respectively, or vice versa. The rod is press-fittable into the cavity. As seen in  FIG. 4 , the rods and cavities may be arranged in a similar manner to the bulbs and sockets discussed regarding  FIG. 2 . 
     As seen in  FIG. 4 , at least one accessory component  900 A,  9008  may be provided with a weighted element. For example, in  FIG. 4 , the second accessory component  900 B comprises a post  10908  around which the weighted element  5  is arranged. 
     The weighted element  5  may be removably attached to the accessory component, which may allow a user to reposition the weighted element  5  with respect to the remainder of the handle assembly  820 . For example, in  FIG. 4 , a user may be able to transfer the weighted element  5  from the first body  910 B of second accessory component  900 B to the first body  910 A of the first accessory component  900 A, and/or to the second body  960 B of the second accessory component  9008  and/or to the second body  960 A of the first accessory component  900 A. In this way, the user may be able to reposition the center of mass of the handle assembly  820 . As a nonlimiting example, the weighted element  5  shown in  FIG. 4  may be used with any of the variants shown in  FIGS. 2-4 . As a nonlimiting example, the handle assembly shown in  FIGS. 1A-B  may be provided with a weighted element having a different form, for example as one or more weighted inserts. 
     Although not shown in the figures, the holding mechanism may comprise a mixture of pairs of bulbs and sockets, rods and cavities, and first and second magnetic elements. 
     Although the figures show pairs of accessory components, it is also foreseen to provide an odd number of accessory components. Moreover, although these figures show multiple accessory components as cooperating with one another (such as by coupling to each other), it is also foreseen to provide at least one accessory component which does not couple to another accessory component. In the examples shown, the accessory components are provided to the side portions of the grip portion, that is, those portions of the grip portion that are directed to the left or to the right of a hand holding the grip portion in a normal orientation of use. Additionally or alternatively, an accessory component may be attached to a back portion of the grip portion, for example to provide a longer handle length to the handle assembly (not shown). The back portion is a portion of the grip portion that is directed to the palm of a hand holding the grip portion in the normal orientation of use. Such accessory components providing a longer handle length may extend beyond the upper end and/or beyond the lower end of the grip portion, the upper end being the one provided with the connection portion  42  or  242 . 
     A handle assembly as disclosed herein may be recycled with ease, owing to the accessory component/components being separable from the handle. 
     A handle assembly as disclosed herein may be recycled, for example, by disassembling the at least one accessory component from the handle or grip portion thereof. The accessory component may subsequently be recycled according to techniques suitable for the accessory component&#39;s constituent materials. As a nonlimiting example, one or more metal recycling techniques, for example one or more ferrous metal recycling technique may be used in recycling the accessory component. 
     Additionally or alternatively, the handle or grip portion thereof may be recycled, subsequent to disassembly of the accessory component (or components) therefrom, according to techniques suitable for the handle&#39;s or grip portion&#39;s constituent materials. For example, one or more plastic recycling techniques may be used. For example, when the handle or grip portion is made of ABS, a plastic pyrolysis technique may be used to convert the ABS into fuel oil. 
     Moreover, unlike known multi-piece handle assemblies, the handle assembly as disclosed herein allows a user to replace one or more items of the handle assembly while conserving the remainder thereof for reuse with replacement items. For example, a user may desire to replace an old handle with a new handle, and to conserve the accessory component/components for reuse with the new handle. Additionally or alternatively, for example, a user may desire to replace one or more old accessory components with one or more new accessory components, and to conserve the handle for reuse with the new accessory component/components.
