Matco's cold chisels are precision ground for cutting, removing and shaping metal, concrete, stone or any other substance which is softer than the chisel's cutting edge.


The cold chisel is made with high carbon, cold - draw, hexagonal steel, is forged and heat - treated, and has a Rockwell hardness (HRc) of 42 - 45 at the cutting edge. The tool can be resharpened with a grindstone of grain 46 to 60, using a liquid coolant so as not to overheat the edge.
