Abstract: A knife has a first part and a second part movably engaged to the first part along a path between an open position in which a housing interior is accessible and a closed position. A holding surface is fixed on and jointly slidable with the second part, and a third part is fixable on the first part, An actuator is movable on the second part between an actuated position and an unactuated position. An arm integral with or fixed on the third part is operatively engaged by the actuator and displaced on movement of the actuator between the unactuated position and the actuated position between a locking position securing the second part in one of the open and closed positions and a release position.
