ABSTRACT:
A utility blade for use with conventional retractable and fixed blade utility knives comprising a blade body having a generally trapezoidal configuration defined by a cutting edge, an opposite back edge, a pair of opposing side edges and a pair of cutting points defined by the points of intersection between the side edges and the cutting edge. The blade further defines a pair of score lines, each proximate to one of the side edges. The score lines enable the user to remove a dulled or damaged cutting point, which in turn provides the user with two additional cutting points defined by the points of intersection between the score lines and the cutting edge. Further, the blade is configured with one or more notches strategically located on the back edge of the blade, such that each cutting point can extend from the utility knife at approximately the same distance.
