8.5 oz. solid titanium bar with open truss design. Patented Dimpler feature creates a recess around the nail head allowing the claws to slide underneath, thereby reducing the chance of chipping the wood. The Clawbar is 5 times stronger than steel bars and has 10 times less recoil shock and 45% less weight. 2 sets of claw tips and strike plate last longer than steel with no mushrooming, rolling, cracking, or tearing.
