Abstract
A three-sided disposable cutting blade for use within a utility knife. The cutting blade features between three and six distinct cutting portions. The cutting blade may be rotated and flipped such that each cutting portion may be presented from the utility knife as the active cutting portion. Features of the cutting blade include a wear-coat indicator which is located at or near each cutting portion and indicates when a portion has been used; grippable locations on the body of the blade to increase the grippibility of the blade when removing and handling the blade; multiple mounting-hole orientations; and mass-reducing punch-outs which reduce cutting friction of the blade against the object being cut.
