Abstract
Abstract A knife for use in skinning game animals such as deer. The knife includes a handle and a unitary, one-piece blade. The blade is constructed in such a manner so as to cause the skin of the animal being skinned to be fed into the cutting edge thereof without causing undue pressure to be applied to the cutting edge and to separate the skin as it is cut and to prevent any portion of the body of the person skinning the animal from coming in contact with the cutting edge.

Claim 1
Independent Claim
351 words
An animal skinning knife comprising: a handle and a unitary one-piece blade means; said blade means including a first member, a second member, and a throat member integrally joining said first and second members together; said first member of said blade means being elongated and having a blunt first end and a blunt second end, said second member of said blade means being elongated and having a blunt first end and a second end and having a top edge and a bottom edge, said throat member of said blade means being elongated and having a blunt first end and a second end and having a first side and a second side and having a top edge and bottom edge, said top edge of said throat member being integrally attached to said bottom edge of said first end of said first member of said blade means, said bottom edge of said throat member being integrally attached to said top edge of said first end of said second member of said blade means, said second ends of said first and second members extending past said second end of said throat member, said first and second sides of said throat member sloping uniformly towards one another from said first end of said throat member to said second end of said throat member to form a wedge-shaped cutting edge terminating at said second end of said throat member for cutting the skin of the animal being skinned and for separating the skin along the cut after it has been cut, said top edge of said second member sloping upwardly relative to said bottom edge of said second member continuously from said second end of said second member to said first end thereof for guiding the skin of the animal being skinned to cutting edge of said throat member and for separating the skin of the animal being skinned from the flesh thereof, said cutting edge of said throat member being straight and being perpendicular to the longitudinal axis of said first member, said handle being fixedly attached to said second end of said blade means.

An animal skinning knife comprising: a handle and a unitary one-piece blade means; said blade means including a first member, a second member, and a throat member integrally joining said first and second members together; said first member of said blade means being elongated and having a blunt first end and a blunt second end, said second member of said blade means being elongated and having a blunt first end and a second end and having a top edge and a bottom edge, said throat member of said blade means being elongated and having a blunt first end and a second end and having a first side and a second side and having a top edge and bottom edge, said top edge of said throat member being integrally attached to said bottom edge of said first end of said first member of said blade means, said bottom edge of said throat member being integrally attached to said top edge of said first end of said second member of said blade means, said second ends of said first and second members extending past said second end of said throat member, said first and second sides of said throat member sloping uniformly towards one another from said first end of said throat member to said second end of said throat member to form a wedge-shaped cutting edge terminating at said second end of said throat member for cutting the skin of the animal being skinned and for separating the skin along the cut after it has been cut, said top edge of said second member sloping upwardly relative to said bottom edge of said second member continuously from said second end of said second member to said first end thereof for guiding the skin of the animal being skinned to cutting edge of said throat member and for separating the skin of the animal being skinned from the flesh thereof, said cutting edge of said throat member being straight and being perpendicular to the longitudinal axis of said first member, said handle being fixedly attached to said second end of said blade means.
Claim 3
Dependent Claim
68 words
The animal skinning knife of claim 1 in which the distance between said top of said second member and said bottom of said first member at said second end of said second member is sufficient to allow the skin of the animal being skinned to pass therebetween while preventing any portion of the skinner's body from inadvertently passing therebetween to thereby prevent the skinner fom inadvertently cutting himself.
Claim 4
Dependent Claim
53 words
The animal skinning knife of claim 2 in which said bottom edge of said first member of said blade means slopes upwardly continuously from a location directly above said second end of said second member to said first end thereof at an angle substantially parallel to said top edge of said second member.
Claim 5
Dependent Claim
