No Heat, No Space, No Problem: With a couple hammer strikes, this chisel cuts off rivet heads and rusted bolts and cleans burrs and rough edges off cast iron, steel, brass, bronze, copper, and aluminum. It's ideal in spaces too tight for a saw and won't overheat the area like a torch. Carefully Balanced: Made from premium, high carbon steel, each chisel is individually heat treated. This carefully controlled process creates a strong, hardened cutting edge while maintaining the temper of the striking end, allowing it to absorb hammer blows without chipping. Finely Tuned Performance: The blade is rough ground after forging and sharpened a second time after heat treating to produce a keen, high-performance cutting edge.
