Shove knife

A shove knife is a forcible entry tool used mainly by firefighters. Generally, they consist of a small, semi-rigid piece of 10 gauge steel with an indented end.^[1] The device is inserted between a door and the door frame, above the spring latch on outwardly-swinging doors equipped with key-in-the-knob locks. The tool is pulled down and outward, releasing the locking mechanism.^[2]^[3]^[4]
