## Title
Blade grip for a knife and method of use

## Abstract

An elongate blade grip is attached to the top edge of a knife blade to achieve greater cutting control and efficiency. The blade grip includes a top member and two opposing side members connected to the top member. The blade grip closely conforms to the flat shape of the knife blade so as to allow knife users to choke up on the knife, or hold the knife partly by the blade. An elongate and rounded top surface on the top member relieves pressure on the proximal phalange of the index finger, thereby reducing blisters and calluses associated with choking up. The side members of the blade grip include slip resistant surfaces where the thumb and medial phalange of the index finger are normally located when choking up on the knife.

## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application depends for priority upon U.S. Provisional Patent Application No. 60/593,843, filed Feb. 17, 2005, which is herein incorporated by reference in its entirety.


FIELD OF THE INVENTION
The present invention relates generally to the field of handheld cutting tools and, more particularly, to grips for cutlery.
BACKGROUND OF THE INVENTION
It is common practice for professional chefs and cooks to hold larger knives, such as an eight-inch or ten-inch chef's knife, with one hand on a portion of the knife blade 20 and on a portion of the adjacent knife handle 22, as shown on FIGS. 1 and 2. The knife blade is pinched on both sides by the thumb 24 and index finger 26 while the ring finger, middle finger, and outermost finger curl under the handle. The other hand is then free to hold a work piece, with fingers often curled and knuckles guiding the knife blade. This technique of holding a knife, referred to herein as “choking up,” has several advantages over simply holding a knife with all four fingers and thumb only on the handle.
The need to prepare food quickly, efficiently, and safely is important in professional and home kitchens. To increase efficiency, culinary workers often prefer to use one large knife to cut small and large work pieces rather than use several knives of different sizes or configurations. This avoids having to find a particular knife and to change from one knife to another, thereby allowing culinary workers to move quickly from one task to the next. However, small work pieces often require more precise cutting, which requires increased control of a knife. Choking up allows culinary workers to increase control over a large knife to achieve precise cuts on small work pieces. Even on large work pieces, choking up allows for better control of cutting angles since the blade sides are stabilized by the thumb and index finger, which are typically a person's two strongest digits. Also, culinary workers with larger hands may find it difficult to comfortably fit all four fingers under the knife handle and, thus, may need to choke up on the knife blade.
When properly choking up on a knife, the knuckle or metacarpophalangeal joint 28 of the index finger is positioned above the interface between the knife blade and knife handle. The proximal phalange of the index finger 30, which is between the metacarpophalangeal joint and proximal interphalangeal joint 32, extends over the top edge 34 of the knife blade so that the medial phalange 36 of the index finger presses against one side of the blade to counterbalance pressure applied by the thumb on the other side of the blade. As such, the proximal phalange of the index finger normally experiences significant pressure from the top edge of the knife blade. The pressure increases at the abrupt ninety-degree corners where the horizontal surface of the top edge meets the sides of the knife blade. As such, repeatedly choking up on a knife often causes a blister to form on the proximal phalange of the index finger, which eventually hardens into a large callous, often referred to as a knife callous or chef's callous.
Many people do not choke up, holding a large knife only by the knife handle 22 because they have not been taught how to choke up in order to achieve better control. Also the knife handle, which is often rounded and ergonomically shaped, serves as a visual cue that discourages many people from placing their thumb and index finger on the sides of the knife blade. Even when people are shown how to choke up, the uncomfortable feel of the smooth, hard surface of the knife blade and the pain from blisters that begin to form on the proximal phalange of the index finger discourage many people from continuing to choking up on a knife.
Prior devices to facilitate use of a knife involve platforms for resting a thumb or tip of the index finger on the top edge of a knife blade in order to force a knife downwards. However, pressing the top edge of a large knife blade with a thumb finger tip is undesirable in many situations, such as when precise control of cutting angle is required. In addition, it is often more efficient and easer to cut a work piece using a forward slicing motion rather than relying on a downward force. Thus, these prior art devices and methods fail to promote choking up on a knife in the proper manner.
Other prior devices to facilitate use of a knife involve protruding handles and knobs. These protruding handles and bulbous knobs do not allow the proximal phalange of the index finger to extend over the top edge of the blade so that the medial phalange 36 of the index finger, not just the finger tip, push against one side of the blade to counterbalance pressure applied by the thumb on the other side of the blade.
Thus, there is an unsatisfied need for an improved method and a device that teaches, aids and encourages persons to properly choke up on a knife in order to achieve better safety through increased control of the knife, while simultaneously relieving discomfort caused by blisters and calluses associated with choking up. Such a method and device would increase efficiency and safety in commercial and non-commercial kitchens alike. The present invention satisfies this and other needs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring now in more detail to the exemplary drawings, wherein like reference numerals designate corresponding or like elements among the several views, there is shown in FIG. 3 a blade grip 40 attached to a knife blade 20. The blade grip includes an elongate top member 42 a top inner surface 44 (FIGS. 6 and 7) and a rounded top outer surface 46. The blade grip also includes two opposed side members 48 that extend along the length of and are connected to the top member. Each of the side members has a side inner surface 50 and a side outer surface 52, which include a slip resistant inner surface 54 (FIG. 7) and a slip resistant outer surface 56, respectively. The outer surface extends smoothly in a downward direction from the top outer surface of the top member.
To attach the blade grip 40 to the knife blade 20, the blade grip is pushed onto the top edge 34 of the knife such that the top edge enters a longitudinal slot between the side members 48 until the top inner surface 44 rests on the top edge. The knife is illustrated in broken lines to better show both sides of the blade grip. The top edge of the knife extends distally from the knife handle 22 in a longitudinal direction indicated as arrow 58. Preferably, the blade grip is positioned along the top edge such that the blade grip is adjacent to the knife handle in order to facilitate choking up. The side inner surface 52 of each of the side members 48 are adapted to grip one side of the knife blade to prevent the blade grip from shifting longitudinally or upward while cutting a work piece.
Preferably, the overall shape of the blade grip 40 conforms closely to the knife blade 20 so to avoid interfering with the balance and function of the knife and with a user's view of a work piece. The top member 42 is preferably thin such that its top outer surface 46 is almost flush or substantially coincident with the top edge of the knife blade. The top member and side members 48 are also preferably thin walled with substantially uniform wall thickness, as described in greater detail below.
FIG. 4 shows the blade grip 40 being used to grasp the knife with one hand using the choking up technique previously described. The orientation and position of the thumb and fingers is guided by the blade grip attached on the knife. As such, professional culinary workers and others who are accustomed to choking up will be comfortable using the blade grip. As illustrated, the proximal phalange 30 of the index finger 26 is wrapped over the top outer surface 46 of the top member 42, which allows the medial phalange 36 of the index finger to drop to one side of the top member. Because the top outer surface 46 of the top member is rounded, pressure on the proximal phalange is substantially reduced compared to when the blade grip 40 is not installed and the proximal phalange makes contact with the abrupt comers at the top edge of the knife. Thus, blisters and calluses associated with choking up are reduced with use of the blade grip. When cutting a work piece, the side outer surfaces 52 of the side members 48 are squeezed between the medial phalange of the index finger and the distal phalange 60 of the thumb. In this way, the cutting angle of the knife blade can be well controlled.
The rounded shape of the top member does not provide a flat or wide platform in order to discourage placement of a thumb or tip of the index finger on top of the knife blade 20, which is undesirable for controlling cutting angle. With a thumb or finger tip on the top of the knife blade, there is also an undesirable tendency for users to cut a work piece with a mostly downward motion. A more efficient cutting method involves moving the knife blade in a longitudinally slicing motion across the work piece, which is encouraged and facilitated by the blade grip 40 as described below.
With continued reference to FIG. 4, the blade grip is attached such that the slip resistant outer surfaces 56 of the side members 48 are positioned where the medial phalange 36 of the index finger and distal phalange 60 of the thumb should be located. The location of the slip resistant outer surfaces 56 provides a visual indication of where to place the thumb and index finger. This visual indication aids persons in learning how to choke up. In addition, the slip resistant outer surfaces 56 allow the user to more easily move the knife blade in a longitudinal, slicing motion, as well as in an up-and-down motion. The slip resistant outer surfaces can also prevent slipping that may occur from the smooth and flat surface of the knife that is often coated by water, oils, juices, sauces, and other liquids common in the kitchen. The slip resistant outer surfaces have a higher coefficient of friction than other surfaces on the side members, which may be achieved by a rough textured area on the side member or tacky material bonded to, coated on, embedded into, or molded on the side member. Suitable tacky materials include, but are not limited to, silicone-based elastomers, which may also provide a soft cushion for comfort.
Referring now to FIG. 5, a side view of the blade grip 40 shows the slip resistant outer surface 56 on the side member 48 with a plurality of circular bumps or protrusions 62, which further prevent the thumb and index finger from slipping. Of course, other suitable types and shapes of protrusions may be employed for this purpose. Only one protrusion is indicated by a reference numeral to preserve the clarity of illustration. The overall proportion of the blade grip 40 is shown by a major dimension 64 running in the longitudinal direction and a minor dimension 66 running perpendicular to major direction. Preferably, the minor dimension or height of the blade grip is limited so as to allow the proximal portion of the knife blade near the knife handle 22 to be used to cut work pieces. At the same time, the major dimension or length of the blade grip 40 is preferably long enough to accommodate the thumb and index finger of a wide range of hand sizes. In particular, the length of the top member 42 should be sufficient to allow the proximal phalange 30 (FIG. 4) of the index finger to extend along and wrap over the rounded, top outer surface 46 of the top member 42. In view of these form factors, the ratio of the major dimension (length) to the minor dimension (height) is preferably at least about 3 to 1.
FIG. 6 shows a cross-sectional view taken along line 6-6 of FIG. 5. The blade grip 40 has a cross section that is substantially u-shaped with an inverted orientation such that the opening is adjacent to bottom portions 68 of the side members 48. In the illustrated embodiment, the bottom portions 68 are configured to form flared lips 72 that extend away from the opening. As such, the flared lips 70 facilitate attachment of the blade grip onto a knife blade 20 by guiding the top edge 34 of the knife blade into the opening adjacent the bottom portions. The side members are preferably biased inward toward the opening to exert a compressive force on the knife blade, thereby helping to prevent the blade grip from shifting in position after it is attached. Even when the side members 48 are biased, their side outer surfaces 52 remain substantially parallel to each other so as to conform to the parallel sides of the knife blade.
The overall physical proportion of the blade grip 40 is also shown by a width dimension 72 (FIG. 6) that runs in a transverse direction perpendicular to the length or major dimension 64 (FIG. 5). As previously mentioned, it is desirable that the blade grip closely conform to the shape of the knife blade so as to avoid interfering with desired thumb and index finger placements. To this end, the width dimension is preferably limited and small relative to the length dimension so as to allow the proximal phalange 30 of the index finger to remain substantially parallel to the longitudinal direction, when desired, while it is extends and wraps over the top outer surface 46 of the top member 42. Accordingly, the ratio of the length dimension to the width dimension is preferably at least about 8 to 1. In addition, as shown in FIG. 3, the width dimension is substantially uniform along the longitudinal direction.
Referring now to FIG. 7, a cut-away side view of the blade grip 40, taken along line 7-7 of FIG. 6, shows the side inner surface 50 of one of the side members 48. As previously mentioned, the side inner surface includes a slip resistant inner surface 54, which is positioned about the bottom portion 68 of the side member that exerts a compressive force on the knife blade 20 to keep the blade grip from shifting during normal use. The slip resistant inner surface has a higher coefficient of friction than other surfaces on the side member, which may be achieved with a thin, tacky material, such as a rubber-like elastomer that may be bonded on, embedded into, coated on, or molded into the side member. In the illustrated embodiment, the slip resistant inner surface includes a plurality of curved grooves 74 intended, in part, to allow liquids to drain away in order maintain friction between the blade grip and the knife blade.
As shown by the cut walls indicated by cross-hatch lines in FIGS. 6 and 7, the blade grip 40 preferably has walls that are thin relative to the overall proportions of the blade grip such that the blade grip conforms closely to the flat shape of the knife blade 20. To this end, the walls of the top member and side members are preferably substantially uniform in thickness. It will be appreciated by those skilled in the art that the configuration of the walls is well-suited for injection molding manufacturing processes since the blade grip may be made in a relatively simple two-half mold cavity with a single linear core pull. The substantially uniform wall thickness allows a molded part to cool quickly and uniformly to avoid warping and sinks, thereby reducing defects and increasing production mold cycle times. Because the design of the blade grip is suited to injection molding, it may be formed from a variety of plastic materials such as polyethylene, polypropylene, polycarbonate, ABS, acrylic, and nylon. Of course, other materials and molding or forming processes may also be used without departing from the scope of the invention. Preferably, the blade grip is made from a durable material that can withstand the high temperatures, abrasive agents, and chemicals of commercial dishwashing processes.
FIG. 8 shows a blade grip 40′ in accordance with another embodiment of the present invention. The slip resistant outer surface 56′ on the side members 48′ includes a plurality of curved grooves 76, which allow liquids to drain away in order to help maintain frictional contact between the blade grip and the thumb and index finger. Other suitable shapes and configurations of grooves, protrusions, and combinations thereof may also be employed for this purpose. One of the curved grooves forms a closed ellipsoid shape, which indicates a pinch point for the thumb or index finger. Such a visual indicator is especially useful when an instruction sheet for choking is included with the blade grip. In addition, the bottom portions 68′ of the side members are chamfered or tapered inward along a substantial length 78 of the blade grip 40′. A work piece rising from below the chamfered bottom portion length 78 of blade grip would be guided away from the blade grip and avoids pushing the blade grip off the knife blade. The proximal end of the bottom portions nearest the handle has a flared corner 80 that extends outward to facilitate pushing the blade grip onto the knife blade when first attaching the blade grip onto the knife.
The benefits of greater control, efficiency, and safety may be achieved by using the blade grip with knives other than the standard chefs knife. Smaller and larger blade grips are contemplated to accommodate knives that are smaller and larger than the standard eight-inch and ten-inch chefs knife and to accommodate a wide variety of hands. Accordingly, the present invention is not intended to be limited to the embodiments described and illustrated.
While several particular forms of the invention have been illustrated and described, it will also be apparent that various modifications can be made without departing from the scope of the invention. It is also contemplated that various combinations or subcombinations of the specific features and aspects of the disclosed embodiments can be combined with or substituted for one another in order to form varying modes of the invention. Accordingly, it is not intended that the invention be limited, except as by the appended claims.
