No Heat, No Space, No Problem: With a couple hammer strikes, these chisels cut off rivet heads and rusted bolts and clean burrs and rough edges off cast iron, steel, brass, bronze, copper, and aluminum. They are ideal in spaces too tight for a saw, and they won't overheat the area like a torch. Extra Long: The generous 12-inch length reaches past obstructions and into narrow spaces that standard chisels can't while still offering the room for you to grip it with your whole hand. 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: Each blade is rough ground after forging and sharpened a second time after heat treating to produce a keen, high-performance cutting edge.
