Abstract
A utility knife includes a handle assembly comprising first and second handle portions pivotally movable between open and closed positions. A blade carriage within the assembly carries a blade. When the handle portions are in the open position the blade carriage is exposed to enable cutting blade replacement. A threaded fastener mounted on the handle assembly includes a knob portion to enable the fastener to be manually moved between a locking position in which the fastener holds the handle portions in their closed position and a releasing position in which the handle portions can be moved between open and closed positions. A detent assembly is operatively connected to threaded fastener to releasably hold the fastener in its locking position. Movement of the second handle portion into its open position pivots an end portion of the blade carriage outwardly away from the first handle portion to facilitate blade replacement.
