Abstract

A utility knife has a body comprising a blade-receiving cavity defined by first and second generally opposing walls; a retention element laterally moveable with respect to the cavity via a hole in one of the walls; an actuator moveable longitudinally relative to the cavity between a retention position and a release position; the actuator having a recess opening towards the cavity and a cam surface; wherein the hole and the recess are aligned when the actuator is in the release position and offset when the actuator is in the retention position; the actuator in the retention position causes the cam surface to engage the retention element to force the retention element to a protruding position in the cavity; the actuator in the release position allows the retention element to be withdrawn, allowing the blade to be removed. Also, a related method of assembly.
