ABSTRACT:
A utility knife has a blade carriage having a blade-receiving bay and moveable relative to the knife's housing to move a cutting blade disposed in the bay from a retracted position to a deployed position. A locking mechanism is operative to releasably couple the cutting blade to the carriage and may include a lock plate having an blade-engagement element and moveable by non-pivoting, generally vertical displacement between a locked position and an unlocked position. An actuator engages the locking mechanism and moves the locking mechanism from the locked position to the unlocked position. The actuator may directly contact an underside of a protrusion of the locking mechanism, may be moveably mounted on the sidewall to which the bay opens toward, may be prevented from being moved as far when the actuator is not aligned with the locking mechanism, or any combination thereof.
