Which tool is inserted between a wood door frame and the door on an outward-swinging door to force the latch back and open the door?

The shove knife is specifically designed for forcing open locked doors, particularly outward-swinging doors. It has a flat, blade-like design that allows it to be inserted between the door frame and the door itself. By applying pressure to the latch mechanism, the shove knife can effectively push the latch back, enabling the door to swing open without needing to damage the door or frame.

In contrast, while the J tool is used for a similar purpose, it is more suited for specific locks rather than all outward-swinging situations. A Slim Jim is typically employed for sliding door mechanisms, allowing for the manipulation of internal components, but it’s not effective on solid or framed doors. The hack saw blade is primarily a cutting tool and not intended for latching mechanisms, making it inappropriate for this type of task. Thus, the design and purpose of the shove knife make it the correct tool for opening an outward-swinging door by manipulating the latch.
