Abstract

A knife comprises a handle, a blade having a blade back, and a hook integral with the blade. The hook includes a hook body extending laterally outwardly from the blade back side of the knife blade. A finger of substantially constant diameter and with no sharp edges extends rearwardly toward the handle from the outward margin of the hook body. The finger preferably has a length of at least about 0.2 inches and is displaced laterally outwardly from the adjacent portion of the knife back by a distance of at least about 1/4 inch. The finger is oriented at an angle to the handle of at least about 5 degrees. A slot defined by the hook body, the finger, and a portion of the blade back includes a straight cutting edge oriented at 90 degrees to the finger, and centering ramps that guide the material being cut into the cutting edge.
