THE SHOVE KNIFE

The shove knife (figure 1) is a forcible entry tool that is used in non-emergency situations. It it used on either inward or outward swinging doors that are secured with a key-in-knob lock or a spring latch. The most common examples would be doors in stairwells, bedrooms, or offices.

Cut out #1 This is used for Figure 1 outward swinging doors. (towards you) Insert the tool either above or below the latch and place the cut out on the back side of the latch. With light pulling pressure on the door, work the shove knife back and forth to work the latch back into the door. If the latch is equipped with a tamper pin, (figure 2) you will need to push the door in until you hear a “click”. This is the tamper pin being pushed into the hole on the striker plate. If you cannot get the pin into the striker plate hole, you will be unable to defeat the latch with the shove knife.

Cut out #2

This is used for inward swinging doors (away from you) and can only be used when a stopped jamb is first pried away. This can be done with a screwdriver or other small tool unless the jamb is a rabbeted jamb. When the jamb is out of the way simply push the knife straight into the latch, provided the tamper pin is inside the striker plate hole, or it does not have one.

Cut out #3 This cut out was originally used for older car door locks and has been left in the design as an option, or nostalgia. A Rabbeted Jamb is a stop milled into a wooden door frame or made as a part of a steel frame.

FIGURE 2

A Stopped Jamb is a wooden door frame with a separate strip of wood nailed to the frame to stop the door from swinging through. Generally, a rabbeted jamb is used for exterior doors and a stopped jamb is used for interior doors.
