Halligan bar

"Created by Hugh Halligan, allegedly modeled on a burglar's tool found in the rubble of a bank fire during overhaul operations.

"[5] — New York City Fire MuseumDespite its popularity among FDNY ladder companies, the department initially refrained from purchasing the tool to avoid the appearance of a conflict of interest.

[8] It consists of a claw (or fork), a blade (wedge or adze), and a tapered pick, which is especially useful in quickly breaching many types of locked doors.

Another variant has an end that resembles a lever-type can opener, used for making large holes for access or ventilation in sheet metal.

The Halligan is available in a number of lengths – typically 18–54 inches (46–137 cm) – and of various materials, including titanium, beryllium copper or stainless steel.
