As I mentioned last week, one of the tools used for forcible entry is the K-tool. This is used with a Halligan and ax(this combination is commonly referred to as “irons”) or with a maul(strong irons). The K-tool is a 3 inch square steel block about 1 inch thick with a K-shaped notch on one side.This tool is used to remove a cylinder lock in a door. The notch is slipped over the lock cylinder. Using the flat side of an ax or the sledgehammer, it’s forced down. The Halligan is inserted into the U-shaped flange on the other side of the K-tool and used to pry the tool off the door. This pulls the key cylinder out, and the bolt can be removed from from the cylinder hole using a screwdriver.
This can be used on most styles of doors, but some have more shields in placethat may make this more difficult and time-consuming. That makes it sometimes faster to use the irons on a solid door. However, the K-tool’s benefit comes in when it would be more impractical or even dangerous to be more aggressive with a door, such as with plate glass windows, where flying shards could injure someone. Or in the case where there is only a suspected fire. A lock can be replaced much easier and cheaper than a whole door.
