Based on traditional tool designs of European stonemasons, our Carbide Rocko Chisel is a specialized hand tool. It offers more control when pitching, trimming, and rock-facing thin or softer types of stone, such as limestone, bluestone, or sandstone. The angled blade allows you to hold the chisel in a more vertical position when striking. This reduces the chance of mis-striking the chisel head, while also reducing the risk of blowing out the underside of your cut. and offers more control when trimming thin or softer stone.
