K-tool

Article summary

The K-tool, also known as a "K-spreader" or a "K-tool spreader," is a specialized forcible entry tool used by firefighters to gain access to buildings or other structures in emergency situations. It is named for its distinctive "K" shape, which allows it to be used for a variety of purposes. It is used in conjunction with a Halligan bar and a flat-headed axe or maul (commonly referred to as "irons" or (with a maul instead of an axe) "heavy irons" ) to remove a cylinder lock with a protruding cylinder. It consists of a steel block roughly 3 inches by 3 inches by 1 inch thick with a K-shaped notch on one side, having sharp edges that grip the end of the cylinder, and a socket to fit the adze of the halligan bar on the other side. The notch is slipped over the lock cylinder, then forced down by striking with the flat side of the axe or maul. The cylinder is forced into the angle of the notch, between the "leg" and "back" of the K. The hard steel bites into the softer metal and provides the needed purchase. The halligan is then inserted into the socket and used to pry the K-tool off the door, thereby pulling the entire key cylinder out. The bolt is then retracted by reaching into the empty cylinder hole with a turning tool, such as a screwdriver.…
