A shove knife is most often used on which type of entry?

A shove knife is a specialized tool that is designed to manipulate locks, specifically those found on outward-swinging doors. This tool works effectively by sliding between the door and the frame to disengage the locking mechanism without causing damage to the door or the frame. Because outward-swinging doors tend to have unique locking systems that can be manipulated this way, the shove knife is particularly well-suited for such applications. In contrast, the other types of options listed—double-hung windows, sliding doors and windows, and casement windows—typically do not have locking mechanisms that can be effectively disengaged using a shove knife, making this tool less effective for those forms of entry.
