Abstract:
A double-ended manual razor is disclosed, with razor on either side of a handle. Each razor is offset from the handle at an opposite angle, with respect to a midpoint between the two razors, that midpoint also being a highest point of the handle, rising from each razor to a pinnacle in a curvilinear manner. One uses the razor by placing at least one finger on either side of the pinnacle and another under the pinnacle, such as in a concave finger region or circle, and pivots around the middle point, pushing either the one or the other razor downwards onto a surface to be shaved. Then, one switches direction and shaves in the other direction with the other razor, always or sometimes placing more pressure on the side of the device with the razor currently in use to shave or cut.

CLAIM OF PRIORITY 
       [0001]    This application in a continuation in part of U.S. application Ser. No. 14/638,258 filed on Mar. 4, 2015, the contents of which are herein fully incorporated by reference in its entirety. 
     
    
     FIELD OF THE EMBODIMENTS 
       [0002]    The field of the embodiments of the present invention relate generally to razors, and, more specifically, to double ended razors. 
       BACKGROUND OF THE EMBODIMENTS 
       [0003]    Shaving is a chore. Men shave their heads and facial hair. Women shave their legs. In a common method of shaving, one has to take multiple strokes adjacent to each other, moving in the same directions. Razors blades are angled and only work in one direction. Attempts have been made to develop razors that work in both directions, but further development is still needed; nothing has removed the old fashioned razor from its throne. Such a razor, held at an acute angle to the elongated handle remains popular. 
       REVIEW OF RELATED TECHNOLOGY 
       [0004]    U.S. Pat. No. 6,560,876 pertains to manual shaving razors. Particularly, the disclosure relates to a shaving razor with a handle with a shaving razor head at each of opposite ends of the razor handle. 
         [0005]    U.S. Pat. No. 4,461,078 pertains to a razor assembly includes first and second handle portions, with first and second razor heads mounted at the ends of the handle portions. The first razor head is adapted to mount a conventional-width razor cartridge, while the second razor head is adapted to mount a styling razor cartridge, the styling razor head having a width about one-third that of the regular razor cartridge. The handle portions are pivotally mounted together so that the heads may be moved from a position wherein the handle portions are substantially in a straight line with the heads widely spaced, to a position wherein the handle portions make a small acute angle with the heads close to each other. The cartridges mounted by the heads are always parallel, and the blades extending from the cartridges are disposed on the same side of the handle 
         [0006]    U.S. Pat. No. 4,989,328 to Sokoloff pertains to a razor assembly includes dual razor heads mounted on a single handle. One razor head is adapted to hold a conventional size blade. The other razor head is adapted to hold a much smaller blade for convenient shaving around one&#39;s nostrils and for trimming of moustaches, beards and sideburns. The user can choose between either razor head simply by rotating the handle with his fingers. 
         [0007]    Thus, various devices and methodologies are known in the art. However, their structure and means of operation are substantially different from the present disclosure. At least one embodiment of this invention is presented in the drawings below and will be described in more detail herein. 
       SUMMARY OF THE EMBODIMENTS 
       [0008]    A double-bladed razor and its method of use are disclosed wherein each of two razors are positioned at either side of a handle, the handle having two sides with each side extending at an acute angle, with respect to a plane defined by the working ends of each razor, to a pinnacle positioned at a center point between each razor. The pinnacle defines a top of the device. When using the device, one can place least one finger directly below the pinnacle of the handle (and this finger either being otherwise un-surrounded by the device or surrounded by a portal of the device). Another finger can be placed above a first of the two sides of the device, with yet another finger above a second of the two sides of the device. Additional fingers can be placed in any of these locations. Then, one shaves in a first direction with a first razor while applying pressure with one of the fingers to this razor, and then switches direction of movement while, in some embodiments, keeping the same orientation of the device, and shaves with the second razor, applying pressure there-on with a different finger. 
         [0009]    The pinnacle further defines a top of a loop enclosed by the handle, in some embodiments of the disclosed technology. A finger, such as a middle finger, can pass through the loop while shaving in the first direction and/or second direction. This pinnacle can be opposite a dimple (also referred to in the disclosure as “concave region”) on a bottom side of the handle, pressing against this dimple while shaving in any direction, such as the first and second direction referenced above. A line of symmetry can pass through the pinnacle be halfway between each razor (a vertical line of symmetry). 
         [0010]    Discussing further the double-sided razor itself, each of two razors are positioned at either side of a handle, in embodiments of the disclosed technology. The handle has two sides each side extended at an acute angle with respect to a plane defined by the working ends (sides used to cut) of each razor. The pinnacle of the handle is positioned at a center point between each razor, the pinnacle defining a top of the device. The handle can have an indentation with a curvilinear surface sized to fit a finger. This indentation can be part of a closed circle. Geometric shapes used in this disclosure can be within 5% (e.g. have a 5% tolerance level) of a true such shape. The indentation can be at a bottom side of the device, beneath the pinnacle and the pinnacle can form part of the indentation (on a top side thereof the material). 
         [0011]    Another way to describe the double-ended razor of embodiments of the disclosed technology is that a first razor at a first end and a second razor at a second end define a lower plane. A handle extend between the first razor and the second razor, upwards from the lower plane until reaching a pinnacle. The pinnacle is at a halfway point between the first razor and the second razor and defines an upper plane. A concave region facing towards the lower plane is formed at the halfway point, which can form a line of symmetry, between the first razor and the second razor. The handle can rise curvilinearly from each of the razors towards the pinnacle. The concave region can be open on the other side of the material forming the concave shape (open to the lower plane) or it can be part of an enclosed circle. 
         [0012]    Using the terminology above, the method of use of such a double ended razor is then described as follows. One presses a finger against the concave region, applying greater pressure on an upper side of the handle at the portion which is between the first razor and the pinnacle than between the pinnacle and the second razor when using the first razor. This is reversed when using the second razor. In other words, one then applies greater pressure on an upper side of the handle between the second razor and the pinnacle than between the pinnacle and said first razor when using the second razor. 
         [0013]    When applying greater pressure between the first razor and the pinnacle, one can move the entire device in a direction more towards the second razor than the first razor (a first direction). When applying the greater pressure between the second razor and the pinnacle, one can move the razor in a direction more towards the first razor than the second razor (in an “opposite” direction, for example). One can then repeat this in a back and forth motion, alternating between placing greater pressure on one side of the device and then on another side of the device at the same frequency as one alternates between going back and going forth. The finger in the concave region can be used to pivot the razor each time one switches between the “back” and the “forth” direction of motion/each time one changes on which side one applies greater pressure to the handle. 
         [0014]    In one embodiment of the present invention there is a razor handle comprising: an arcuate handle having a first end and a second end with each of the first end and the second end having a pair of coupling legs, the pair of coupling legs being configured to engage a recess of a first razor retainment body and a second razor retainment body; and two handle supports being coupled to the arcuate handle, with each of the two handle supports being configured to abut a portion of the first razor retainment body or the second razor retainment body.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0046]    The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals. 
         [0047]    Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto. 
         [0048]    Embodiments of the disclosed technology include a double-ended razor/shaver with an arched handle extended there-between. The arch rises at an acute angle with respect to each razor, while each razor is attached at a mirrored angle from one another, with respect to a center point of the device between each razor. At the center point of the device is a pinnacle or raised area, defining an uppermost extremity of the device (where the reverse side of the razors form a lower side thereof). This pinnacle allows a person to place a finger underneath same, and use this finger as a “pivot” point to angle one razor, then the other further downwards. As such, one can shave in a first direction, and then reverse course and shave in an opposite second direction. 
         [0049]    It should be understood that “razor” can include any cutting device, and is further used herein, and in the claims, to refer to either a “cutting device” or an “end of a handle where a cutting device attaches.” 
         [0050]    Embodiments of the disclosed technology will become clearer in view of the following discussion of the figures. 
         [0051]      FIG. 1A  shows a perspective view of an arched double-sided razor in an embodiment of the disclosed technology.  FIG. 1B  shows a perspective view of a double-sided razor with finger portal in an embodiment of the disclosed technology. Elements of the arched embodiment are incremented by  100  for analogous or related parts of the finger portal embodiment. 
         [0052]    Discussing first the arched embodiment  100 , two razors  110  and  112  are disposed at opposite ends of the device. The business or working end of each razor points in a mirrored direction, which can include being connected to the handle at a mirrored angle. A “mirrored” angle, for purposes of this disclosure, is one in which has the same number of degrees, in absolute value, off from a vertical access passing perpendicular to the upper most extremity of the device. The “upper” extremity is defined by the arch  150  having a pinnacle in the center of two sides  160  and  170  which angle downwards towards each razor  110  and  112 . This pinnacle is also the horizontal center of the device. 
         [0053]    Under the arch is a cavity  155  which can be curvilinear, concave, and/or adapted for abutment by a finger such as the middle finger. Beneath the side  160  of the handle is a location  165  for placement of another finger, such as the index finger. Beneath the side  170  of the handle  170  is a location  175  for placement of yet another finger, such as the ring finger. The arch  150  is defined as beginning and ending where the derivative of the slope changes between a razor and pinnacle from a positive to a negative, or negative to a positive, closest to the pinnacle. This is further defined such that the arch  150  ends where the slope of the underside of the handle stops having a greater increase than previously, relative to a line formed from the razor to pinnacle. This is still further defined as an area beneath the handle which is concave; once the underside of the handle becomes convex, it is no longer part of arch  150 . 
         [0054]    Discussing in greater detail the areas exterior to the handle, above the handle between the arch  150  and razors  110  are two areas  162  and  172 , on either side. A finger may be placed in one of these positions and a second finger, in the other position. Below the handle, between the arch  150  and each razor are two lower positions  165  and  175 . A finger may be placed in one of these positions and a second finger, in the other position. A finger can also be placed within the concave cavity  155 . In any of these cases, the finger rests or applies pressure on the handle extending between the two razors, either on the upper or lower side thereof. As such, greater pressure can be applied to one or the side of the device, against a person. 
         [0055]    Referring now to the finger portal embodiment  200  and  FIG. 1B , the arch  150  of the prior embodiment is replaced with a finger portal  257 . This portal can be circular, oval, ovoid, square, rectangular, or the like. The finger portal  255  is within a closed loop  250  of any shape, in embodiments. This closed loop  250  reaches the pinnacle of the device, again halfway between the razor  210  and  212  and forms a vertical line of symmetry. The handle extends from this closed loop to one side of the handle  260  and the other side of the handle  270  with an area beneath,  255 . In use, one places a finger though the finger portal  250  and at least two additional fingers either above and/or below the left portion  260  of the handle and right portion  270  of the handle. 
         [0056]      FIG. 2A  shows a top and side perspective view of the device shown in  FIG. 1A .  FIG. 2B  shows a top and side perspective view of the device shown in  FIG. 1B .  FIG. 3A  shows a bottom view of the device shown in  FIG. 1A .  FIG. 3B  shows a bottom view of the device shown in  FIG. 1B . 
         [0057]      FIG. 4A  shows a side elevation view of the device shown in  FIG. 1A .  FIG. 4B  shows a side elevation view of the device shown in  FIG. 1B . In an embodiment of the disclosed technology, the dimensions of the elements shown in  FIGS. 4A and 4B  are precise and can be used to determine actual angles and/or dimensions of such embodiments represented therein. 
         [0058]      FIG. 5A and 5B  shows a top view and a bottom view of the double-sided razor of  FIG. 1A . In using the razor as shown, the razor  100  is placed against a leg  10 . The leg  10  has shaving cream  11  there-on. A middle finger  3  is placed below the arch  150 , between the leg  10  and the device  100 . An index finger  2  is placed above the handle of the device  100  between a razor  112  and the arch  150 . A ring finger  4  is placed above the handle of the device  100  between a razor  110  and arch of the device. The device  100  is situated between the leg  10  and the index  2 /ring  4  fingers. 
         [0059]    The razor  100  can then be moved in a downwards direction  20 , towards the foot. The razor  112  is against the leg  10  and as such, there is greater pressure applied on the handle of the device  100  by the index finger  2  than the ring finger  4 . When switching directions and going back upwards, away from the foot, the device remains in the same orientation (razor  112  above the razor  110 , relative to the leg, other body part being shaved, and/or relative to the surface of the earth), but moves in a generally or substantially opposite direction with pressure applied being greater from ring finger  4  than index finger  2 . 
         [0060]      FIG. 6  shows a method of using the finger portal double-sided razor of  FIG. 1B .  FIG. 7  shows the embodiment of  FIG. 7 , moving in the opposite direction. Here, the finger portal device  200  is shown, first moving in a downward direction  20 , and then in an upward direction  22 . It can be seen that when finishing in a first direction, then the person reverses direction (defined as 180 degrees and/or within 5, 10, 20, 30, 46, 60, or 90 degrees thereof) and uses the other razor on the double-ended razor device, but keeps the device itself in the same orientation (having a change in direction less than and/or equal to 5, 10, 20, 30, 45, 60, or 90 degrees). 
         [0061]    Referring now to  FIGS. 8-13 , there is another embodiment of the present invention. Here, a dual or double sided razor  300 , generally has a first razor retainment body  305 , a second razor retainment body, retainment body recess  315 , coupling legs  320 , retainment body supports  325 , leg foots  320 , handle supports  335 , an arcuate handle  340 , and a leg body  350 . 
         [0062]    The arcuate handle  340  is generally arcuate in shape and configured to form an ergonomic hold for the user. As shown in  FIG. 14 , the user may place their index finger  440  and ring finger  420  on an upper surface of the arcuate handle  340 . The index finger  440  and the ring finger  420  may be permitted to further rest on a portion of an upper surface of the first razor retainment body  305  and the second razor retainment body  310 . The middle finger  430  may be positioned along a lower surface of the arcuate handle  340 . However, various other finger configurations may be employed by the user when utilizing the present invention. 
         [0063]    The arcuate handle  340  further defines coupling legs  320  and leg feet  330 . The coupling legs  320  are disposed at each of a first end and a second end of the arcuate handle  340 . The coupling legs  320  may be organized in pairs with each pair being coupled to one of the preferable two razor retainment bodies employed by the present invention. 
         [0064]    Each coupling leg  320  generally comprises a leg body  350  and leg foot  330 . As shown in  FIG. 13 , the leg feet  330  are protrusions that extend generally perpendicularly from the leg body  350 . The leg feet  330  are configured to engage recesses  315  on the razor retainment bodies. This engagement thereby couples the arcuate handle  340  to the razor retainment bodies. In order to complete the coupling process, a user may gently compress the coupling legs  320  inwards thereby allowing the protruding leg feet  330  to slip into the recesses  315 . A reverse procedure may be utilized remove and/or replace the razor retainment bodies. 
         [0065]    In addition, the arcuate handle  340  supports at least one and preferably two handle supports  335 . The handle supports  335  may have the same general arcuate flow as the arcuate handle  340  thereby enabling a comfortable grip for the user. Further, the handle supports  335  are configured to abut or engage a retainment body support  325 . When the arcuate handle  340  is coupled to the razor retainment bodies, the handle supports  335  are aligned with the retainment body supports  325 . The handle supports  335  are shaped such that this relationship between structures prevents or limits rotation of the razor retainment bodies while the razor  300  is in use by the user. This enables an optimal shaving angle to be persistently and consistently maintained. 
         [0066]    In some embodiments, it may be desirable that a shaving surface of the razor retainment bodies lie in the same plane (i.e. are flat with respect to one another). However, in other embodiments, it is preferable that the razor retainment bodies lie in different planes. Further, deviations (from parallel or flat) may be up to ±10°. In some embodiments, the particular angle formed by one of the razor retainment bodies may be the same or different as the other razor retainment body. 
         [0067]    As shown in  FIG. 11 , the arcuate handle  340  has a first distance or width denoted “D” and the coupling legs  320  having a second distance or width “D′.” The coupling legs  320  are configured to have a D′ that is larger than the D of the handle thereby providing for enhanced stability and providing for the remaining of the physical structure of the arcuate handle  340  to be properly maintained. 
         [0068]    Referring now to  FIG. 14 , there is an illustration demonstrating one method of using the embodiment described in  FIGS. 8-13 . Here, a user may put shaving cream or foam  400  on their leg  410  or other bodily surface to be treated with the razor  300 . The user then positions their fingers along the upper surface and the lower surface of the arcuate handle  340 . It is preferable that only one of the two razor retainment bodies (having razors blades contained therein) is in contact with the skin surface at any one given time. 
         [0069]    In practice, the trailing razor retainment body should be in contact with the skin surface whereas the user&#39;s hand position is such that the leading razor retainment body is slightly elevated off the skin surface. This allows the trailing body to be the sole body cutting. In some arrangements, the razor retainment bodies, namely the razor blades, may be configured such that both are intended to be in contact with the skin surface thereby cutting in the same direction. However, this would prevent the desired “back and forth” contemplated by the present invention and its embodiments. 
         [0070]    It should be understood that any configuration of the fingers can be used and any body part can be shaved with this method/device. For example, one can place two fingers on each side of the arch/finger portal, two fingers in the portal or under the arch, a finger above and below one side of the handle with another under the arch or in the finger portal, or the like. Any configuration allowing the user to press a razor against an area to be shaved can be used. 
         [0071]    Still further, it should be understood that while a leg is shown in the drawings, this device has other applications, such as to shave a head. One can use the above-described methods to go back and forth over a head to shave, alternating which razor is used to shave with each change between the “back” and “forth” direction. 
         [0072]    Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
