This set includes the BHP Type II hammer and the CNC sear. This hammer provides you with a distinctively different type of opening, however this hammer may not work with a custom beavertail due to clearance issues. The edges of the hammer are chamfered for comfortable non snag carry. Made from our special tooled steel and Rockwell C tested at 50-55. The sear is cut from tool steel plate stock by CNC wire EDM and finish machined on CNC machine to exacting tolerances. Each part is 100% inspected and checked for proper RC hardness. Heat treated to 50-55 Rc.
