Abstract
A utility knife is provided which includes a unitary, blade carrier which acts to restrain the blade during heavy use and which prevents the blade from disengaging from the knife. The blade carrier includes a blade support portion, a blade retaining flange for retaining a first edge of the blade, and at least one laterally extending post for receiving a corresponding notch or notches in the blade when the blade is mounted on the blade carrier. The post has a profile which engages the notch in the blade when the blade is subjected to a lateral or twisting force to prevent the blade from disengaging from the blade carrier during use. In this manner, the post on the blade carrier performs the dual function of providing both longitudinal as well as lateral restraint for the blade.
