A Guide to Maintaining a Cold Chisel's Cutting Edge
Cold chisels, named for their use on metal that hasn't been heated, are usually crafted from treated steel rods with hexagonal or octagonal shapes. One extremity is tapered and ground to a sharp edge, while the opposite end is flat with beveled edges to endure hammer strikes. The tool is heat-treated for strength, and the cutting angle is chosen based on the metal being worked. Regular sharpening keeps the chisel usable for years.
