Abstract
A safety use deboning knife includes a blade having a distally disposed carcass flesh penetration tip disposed immediately adjacent the blade curved cutting edge and spacedly disposed from the blade non-cutting upper edge by a planar distal edge, which distal edge subtends an acute angle of less than about 45° and preferably in less than about 25° with entire cutting portion disposed below the blade center line.
Claims27
A deboning knife comprising:
- a handle;
- a blade disposed in the handle, said blade comprises a proximate end and a distal end, and upper edge and a lower edge, said lower edge comprises a cutting edge comprising a curved portion;
- said distal end comprises a distal edge and a penetration tip, said penetration tip being disposed more adjacent the lower edge than the upper edge;
- wherein the user in gripping the handle penetrates the carcass flesh with the penetration tip and applies a leverage force with the distal end to readily effect the deboning while minimizing the prospect of cutting the user.
A method for deboning a carcass comprising:
- (a) providing at least one deboning knife, said deboning knife comprises:
- a handle;
- a blade disposed in the handle, said blade comprises a proximate end and a distal end, and upper edge and a lower edge, said lower edge comprises a cutting edge comprising a curved portion;
- said distal end comprises a distal edge and a penetration tip, said penetration tip being disposed downwardly and distally from the upper edge;
- and
- (b) piercing the flesh of the carcass with the penetration tip;
- whereby the carcass flesh is penetrated by the penetration tip to a sufficient depth so that an effective leverage force is generated at the distal end while minimizing the prospect of cutting the operator's flesh.
A method for deboning poultry comprising:
- a) providing a plurality of deboning knives, each said deboning knife comprises:
- a handle;
- a blade disposed in the handle, said blade comprises a proximate end and a distal end, and upper edge and a lower edge, said lower edge comprises a cutting edge comprising a curved portion;
- said distal end comprises a edge tip comprising a penetration tip, said penetration tip being disposed downwardly and distally from the upper edge;
- (b) gripping the handle with a glove comprising substantially polymeric material;
- (c) piercing the flesh of the poultry carcass with the penetration tip;
- (d) applying leverage force to the distal end;
- whereby the poultry carcass flesh is penetrated by the penetration tip to a sufficient depth and an effective leverage force can be generated by the distal end while minimizing the prospect of cutting the operator's flesh.
A deboning knife blade, said blade comprises an upper edge, a lower edge comprising an upwardly curved cutting edge, a distally disposed penetration tip disposed adjacent the lower edge, and a blunt edge disposed between the upper edge and the penetration tip, said blunt edge subtends an angle of from about 8° to 44° with the vertical V, and said angle is commensurate with increases proportionally with the extent of upward curvature in the cutting edge.
A set of deboning knife blades comprising a plurality of blades, each said blade comprises an upper edge, a lower edge comprising an upwardly curved cutting edge, a distally disposed penetration tip disposed adjacent the lower edge, and a blunt edge disposed between the upper edge and the penetration tip, said blunt edge subtends an angle of from about 8° to 44° with the vertical V, and said angle is commensurate with increases proportionally with the extent of upward curvature in the cutting edge.
