Patent Application

The present invention relates to a tool, and a method using the tool, for skinning game animals. Specifically, the present invention relates to a curved blade knife, sharpened on the curved, top edge, and possessing a sphere or a non-spherical element at the tip. The tool is used by forming a cut through the soft skin of a game animal, inserting the spherical or non-spherical tip through the cut, and pushing or pulling the blade such that the sharpened curved, top edge cuts through the skin. This tool and method takes advantage of the fact that because the spherical or non-spherical tip is partially retained inside the skin and connective tissue of the game animal, the blade is properly positioned to cut the skin and subordinate connective tissue of the game animal.
Currently, the method of skinning a game animal after death is very generic: The hunter uses a knife to incise and remove the skin and underlying connective tissue of the animal. The chief difficulty has to do with controlling the depth of the incision used to remove the skin and connective tissue. Such incisions tend to be long and shallow and are difficult to make using a straight bladed knife.
What is needed then is a knife with a spherical or non-spherical tip such that the spherical or non-spherical tip is retained beneath the connective tissue of the skin as the knife is moved to incise the skin and connective tissue.
What is also needed is a knife where the top edge of the blade is sharpened and the lower edge of the blade is unsharpened.
What is also needed is a knife with a concavely curved blade from tip to handle.
What is also needed is a knife with a puncturing tip for making a hole in the skin and connective tissue of the game animal.
Finally, what is needed is a method of using the above described knife to skin a game animal.
One embodiment of the present invention is a skinning knife with a blade and a handle both aligned lengthwise along a generally linear axis. In one embodiment of the present invention, the handle is comprised of external covers retained to the handle by means of screws. It will be readily apparent, however, that these external covers may be integrally formed along with the handle or may be adhesively or flexibly applied. For example, a textured rubber external cover may be flexibly applied to the handle of the skinning knife.
The blade of one embodiment of the present invention is sharpened along the top edge. The bottom edge of the blade is unsharpened and flat or curved in cross section for safety purposes. The sharpened top edge of the blade is concavely curved along its length from the handle to the tip. There is a spherical or non-spherical structure at the tip of the blade and a pointed, piercing structure on the same side of the blade just in front of the handle. The spherical or non-spherical structure is used to retain the tip of the blade in the puncture wound made where the skinning incision is to begin.
The handle and the blade may be jointed or fixed. In the case where they are jointed, the blade folds into the handle such that the sharpened top of the blade is insinuated inside the handle. In this case the spherical or non-spherical structure at the tip may be stored outside of the handle when the blade is closed.
The knife is used in the following manner: First, if the blade is jointed, the blade is rotated out of the handle and allowed to lock into a generally linear alignment with the handle. Next, the pointed piercing structure just in front of the handle is positioned against the soft skin of the game animal. Next the pointed piercing structure just in front of the handle is driven through the skin and connective tissue forming a puncture wound leading underneath the skin. Alternately, this incision may be made with the tip of a separate knife. Next, the knife and pointed piercing structure just in front of the handle are rotated such that the spherical or non-spherical structure at the tip of the blade is positioned inside the game animal in the puncture wound formed previously. Next, the user pushes or pulls the blade using the handle incising the skin and connective tissue of the game animal. The spherical or non-spherical structure at the tip of the blade retains the tip of the blade at the proper depth underneath the connective tissue to easily incise only the skin and connective tissue. Next, when the incision has been completed, the spherical or non-spherical structure at the tip of the blade is removed from the incision. Finally, if the blade is jointed, the blade is rotated into the handle.

Blade 103 of one embodiment of the present invention is sharpened on the curved top edge 104. Bottom edge 107 of blade 103 is unsharpened and flat or curved in cross section for safety purposes. Sharpened curved top edge 104 of blade 103 is concavely curved along its length from the handle to the tip. Spherical or non-spherical structure 106 is positioned at the tip of the blade and pointed, piercing structure 105 is positioned just in front of handle 101. In one embodiment of the present invention pointed, piercing structure 105 is absent from the invention.
Handle 101 and blade 103 may be flexibly jointed or fixed. In the case where they are flexibly jointed, blade 103 folds into handle 101 such that sharpened curved top edge 104 and pointed, piercing structure 105 of blade 103 are insinuated inside handle 101. In this case, spherical or non-spherical structure 106 at the tip may be stored outside of handle 101 when blade 103 is closed inside of handle 101.

The present application explicitly includes all variants of the present invention readily apparent to a person having skill in the art. For example, spherical or non-spherical structure 106 at the tip of blade 103 may be formed in other cross-sections, including: 1) Ovoids; 2) Thickened plates; and, 3) Internally sharpened hooks. Also, the blade of one embodiment of the present invention is constructed of steel, but those having skill in the art will recognize that other substances may be used including: 1) Carbon fiber; and, 2) Ceramic. Also, the specification calls out pushing blade 103 through the skin and subordinate connective tissue. Clearly, embodiments where blade 103 is pulled are equally well contemplated and disclosed.
Spherical or non-spherical structure 106 may be solid or open and hollow in form. If open and hollow in form, the open structure may be formed of wires or curved rods. The ovoid shape referenced supra may also be solid or open in form. If open in form, the open structure may be formed of wires or curved rods. Also, the long axis of the ovoid form may be aligned linearly along a lengthwise axis of the blade 103 or at any angle with respect to a lengthwise axis of the blade 103 including tangentially or perpendicularly to a lengthwise axis of the blade 103. The thickened plate referenced supra may be uniformly thick or may have a varying shape and thickness. The thickened plate may be thicker at the end most distant from handle 101 or it may be thicker at the end most proximal to handle 101. Finally, the thickened plate may be any shape and oriented at any angle with respect to the blade 103.
For example,
Also, blade 103 may not be affixed to a handle. It may exist only as a blade 103 which may be manually attached or affixed to a handle assembly.
