What type of doors are shove knives commonly utilized on?

Shove knives are commonly utilized on outward swinging doors. These tools are designed to assist firefighters in gaining access through locked or blocked doors that swing away from the user. Outward swinging doors present a unique challenge because they are often secured in a manner that makes it difficult to manipulate them from the outside. The design of the shove knife allows the user to insert it between the door frame and edge of the door to disengage the locking mechanism or latch, facilitating a quick entry during emergencies.

While inward swinging doors can also present access challenges, they typically allow for a different set of methods for entry, such as prying or forced entry techniques. Firewall doors serve a specific purpose within building safety and are generally equipped with more robust locking systems which may not be effectively manipulated with a shove knife. Wooden doors are simply a material type and do not specifically dictate the functionality or application of a shove knife. Thus, the unique requirements of outward swinging doors make them the primary application for this type of tool.
