DETAILED DESCRIPTION OF THE INVENTION

[0022] A grip can be the implementation of one or more etchings. The grip can help with precision and safety of the knife holder when completing finer tasks. The etchings can allow the holder to have a better grip on the knife when choking-up on the knife. Choking-up can be common for completing finer tasks with a knife, but there can be safety and leverage problems when doing so with regular knives. The etchings can help prevent the fingers from sliding, while also making sure the holder has improved leverage.

[0023] An etching can be near the middle of the blade. The blade etching can be for the thumb of the holder and can be sized accordingly. In some embodiments the point of the etching is to make sure a portion of the hand has increased grip (e.g. the thumb does not slide off the blade). Increased grip can be advantageous when completing finer tasks. The etching can be a deep indent for the thumb. The etching can be some design that allows for more friction than the side of a metal blade.

[0024] An etching can also be on the opposite side of the blade. The etching can allow another portion of the hand (e.g. the index finger) to have increased friction on the blade as well. In some embodiments, the etching is one section, and in other embodiments the etching wraps around the blade.

[0025] In some embodiments, the blade can have more than one type of edge. These embodiments can include a chopping edge, a fine-task edge, and a chisel edge. These features may be contiguous. In some embodiments, the chopping edge is the closest edge to the handle, followed by the fine-task edge leading to the tip of the blade being replaced by the chisel edge.

[0026] In some embodiments, the knife has a chopping edge. The chopping edge may be the closest edge to the handle. In some embodiments, the chopping edge can consist of the blade having a gradual gradient on both sides leading to a point. In some embodiments, the chopping edge is accompanied by a metal piece on the handle which can protrude from the handle on the side of the handle where the blade is sharp. The metal piece can be between the index and middle finger placement. The metal piece can enhance the grip of the user when chopping.

[0027] In some embodiments, the knife has a fine-task edge. In some embodiments, the fine-task edge is adjacent to the chopping edge. In some embodiments, the fine-task edge is further from the handle than the chopping edge. In some embodiments, the chopping portion of the knife can start at the handle and extend to a point where the blade can go from sharpened on both sides to only sharpened on one side. The fine-task edge may only have a blade gradient on one side of the blade. In some embodiments, the fine-task edge can be accompanied by the fine task friction grip.

[0028] In some embodiments, the blade can end in a sharpened flat end for chiseling. In this same embodiment the knife can include the metal of the blade protruding past the back of the handle to be used as a point to bang, a mallet or other hammer-type object, against when the chisel feature is being used.

[0029] In some embodiments, the blade can be specifically made to reinforce precision and balance. In some embodiments, the balance can be towards a top-blade heavy balance to help with the chopping function of the knife. The top-blade heavy balance allows for the easier production of force for chopping following naturally from a higher angular momentum created then if the center of mass was in the handle of the blade.

[0030] FIG. 1 depicts one embodiment of the multipurpose knife. The knife (100) has a protruding metal piece (110) on the handle to aid in chopping. The point where the blade goes from being sharpened on both sides to only being sharp on one side (120) is the area below where the etching can be in some embodiments. The embodiment also includes a flattened tip (130) and a protruding metal piece in the back of the handle (140) to aid in the chiseling function.

[0031] FIG. 2 depicts the handle of the knife in some embodiments. The index finger can be separated from the rest of the fingers in some embodiments through the protrusion of a metal piece on the handle (210). The handle, in some embodiments, can have a metal piece protruding through the back of the handle (220) to be hit when trying to use the chisel function of the knife. In some embodiments the piece can have a hole for being connected to a bag or lanyard.

[0032] FIG. 3 depicts one embodiment of the knife including the multi-purpose feature and an etching in the shape of a decorative logo. The knife (300) has the flat end for chiseling along with the fine task and chopping features with the change from blocking to fine task feature occurring directly adjacent to the logo etching (310). The embodiment also includes the separation of the index finger from the other fingers on the handle (320) to aid in chopping.

[0033] FIG. 4 depicts the dimensions for one embodiment of the outdoorsman knife (400). In this embodiment the chisel end of the blade includes one side being sharpened with a 25 degree gradient (410). In this embodiment, the blade thickness is 6.35 millimeters (420). In this embodiment, the chisel feature (430) can span for 25.40 millimeters, while the blade can be 44.45 millimeters wide. The logo etching (440) in this embodiment can be 63.52 millimeters from the end of the knife and having the dimensions of 19.04 millimeters by 17.88 millimeters. In this embodiment, the knife also includes the index finger slot (450) being 19.05 millimeters wide. One skilled in the art will recognize that the blade measurements can vary in different embodiments.

[0034] FIG. 5 depicts one embodiment of the multi-purpose knife with an etching grip. This embodiment includes the three-purpose knife (500) with an etching grip (510) on the blade for fine tasks. In this embodiment, the etching (550) is an overlay of a logo etching (560) on top of a fingerprint etching (570).

[0035] FIG. 6 depicts one embodiment of the multi-purpose knife. In this embodiment, the chisel blade feature (610) is at the end of the blade being followed by the fine task edge (640) with the chopping edge (620) spanning from the end of the fine task edge to the handle. This embodiment contains slight curvature towards a point at the end of the blade before the chisel feature impedes this curvature.

[0036] FIG. 7 depicts one embodiment of the multi-purpose knife with a decorative fingerprint etching. In this embodiment, the etching (710) is decorative in the shape of a fingerprint (750). In this embodiment, the knife (700) has the etching adjacent to where the blade goes from sharpened on both sides to only sharpened on one side. In some embodiments, the first etching would be accompanied by another etching on the opposite side for the index finger when completing fine task cutting.

[0037] FIG. 8 depicts one embodiment of the multi-purpose knife. In this embodiment, the knife has an etching in the shape of a thumb (800) on the side of the blade near the tip of the knife to add friction to the user's grip. This embodiment of the knife does not have a protruding metal piece on the handle of the knife (810) to separate the index finger from the rest of the fingers like it does in some embodiments. In this embodiment the handle of the knife has a hole at the bottom end of the handle (820) for being connected to a bag or lanyard.
