A chisel is a hand tool with a characteristic wedge-shaped cutting edge on the end of its blade. A chisel is useful for carving or cutting a hard material such as wood, stone, or metal.
Using a chisel involves forcing the blade into some material to cut it. The driving force may be applied by pushing by hand, or by using a mallet or hammer. In industrial use, a hydraulic ram or falling weight ('trip hammer') may be used to drive a chisel into the material.
A gouge is a type of chisel that serves to carve small pieces from the material; particularly in woodworking, woodturning and sculpture.
