ABSTRACT:
A forcible entry tool includes an elongate pry bar having at one end a cutting section comprising a gripping block and a cutting blade. The gripping block has a forward gripping pad which acts as a fulcrum point, about which the tool can pivot. The blade can be thrust towards the material to be cut to pierce through the material, or alternatively, the tool can be swung like an axe to cut through the material. In either event, after an opening is formed in the material, the cutting blade can be inserted into the opening with the gripping block above the material. Continued pumping of the pry bar about the pivot point transfers a cutting force to the cutting blade to shear the material. Alternate tool portions such as prying heads and saw blades can be installed at the opposite end of the bar for various other uses.
