These Chisels are designed for more laborious removal of stone, or work with harder stones. The tips are ground at a lower angle to prevent breakage, and allow more energy to be transferred to the stone. The grade of Tip is also specific to this chisel, so that it will tolerate more energetic use, without fear of breaking. The Chisel bodies are also bulked up, to support the tip, and also give the mason something to hold onto when working with such tough materials. These Chisels are ideal for fast removal of stone to rough shape, and also finishing to shape. Available as Standard Flat Tip, Or Bullnose.
