ABSTRACT:
A knife blade having a cutting edge with a first end and a mounting edge opposite the cutting edge. Typically the first end will be a point, but other configurations are possible. In addition, the knife blade has a first attachment slot extending from the mounting edge toward the cutting edge and away from the first end. The first attachment slot may be tapered at a select taper angle. In addition, the first attachment slot may include a first segment extending from the mounting edge toward the cutting edge and a second segment extending from the first segment away from the first end. Similarly, a third segment of the first attachment slot may extend from the first segment toward the first end. In one embodiment, the first, second, and third segments form a substantially “T” shaped attachment slot. Preferably, the second and third segments of a “T” shaped attachment slot are tapered at a select taper angle from the junction with the first segment.
