US Patent 11370135 Firefighter's ax

A combination tandem cutting ax head and adz is disclosed that is adapted to firefighting. The ax may include a front end that is divided between a concave portion and a flat section. The concavity creates edges for cutting through surfaces, while the flat section functions to hinder the ax head from becoming wedged in the material. An adz may be provided in which the fulcrum is raised above the head and located between the handle and the adz edge, which increases the lever arm.
