Abstract
A utility knife has a blade carriage having a blade-receiving bay and moveable horizontally 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 includes 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 move from a first position to a second position in unlocking the locking mechanism, optionally vertically, with the second position being not closer to the midline of the utility knife than the first position. The blade-receiving bay may face the side of the housing that supports the actuator for the locking mechanism.
