Charring chisel
The charring chisel is a wide, metal stonemason’s chisel with straight,
double cutting edge, the angle of which is between 10 ° and 40 °, depending
on the hardness of the worked stone. The width of the cutting edge can
range from about 3.5 to 18 cm. There are charring chisels with a wooden
handle for softer types of stone. For technical information on this page
