Abstract

The knife includes a handle portion attached to a blade with a tip at its distal end. The blade comprises four surfaces that converge to form a spine and opposing cutting edges with each surface having a concave segment, a first angled segment, a flat segment, and a second angled segment as the surface extends from the spine to the edge. Similarly, the tip includes four surfaces that converge and terminate at a point, with each surface comprising only an angled segment. Optionally, the knife includes a unique safety lanyard that has two attachment points on the handle such that a closed loop is adjustably formed around the user's hand when gripping the handle, which aids in withdrawing the knife, stabilizing the user's grip, and preventing the hand from sliding forward while in use. Optionally, the knife includes a thumb plate as an additional safeguard.

Dependent claims

A knife blade comprising:

a blade portion with a tip at its distal end,
said blade portion comprising a first top surface, a second top surface, a first bottom surface, and a second bottom surface, each surface having a first side and an opposing second side,
wherein the first side of the first top surface and the first side of the second top surface intersect to define a top spine joint, wherein the first side of the first bottom surface and the first side of the second bottom surface intersect to define a bottom spine joint, wherein the second side of the first top surface and the second side of the first bottom surface intersect to define a first cutting edge, and wherein the second side of the second top surface and the second side of the second bottom surface intersect to define a second cutting edge,
wherein a spine of the blade is defined as a vertical plane between the top spine joint and the bottom spine joint, and
wherein each surface of the blade portion extending from the spine to a respective one of the cutting edges comprises a concave segment, followed by a first angled segment, followed by a flat segment, followed by a second angled segment.
