Zak Tool Shove Knife Door Pick Tool ZAK-64
The Shove Knife is the fastest, damage free means of opening residential, office interior doors with key in the knob locks. Used extensively in fire towers to slip spring latch locks. The design makes the knife work from either side of the door. If the door opens inward, you shove the knife in back of the molding stop and retract the latch. For doors that open towards you, the knife is slipped in from above or below the latch point and jiggled and pulled to retract the latch. A protective sleeve is added when not in use.
