The tool on the cover of PDF Hacks is a sledge hammer. The sledge hammer is a heavy hammer with a long handle designed to drive wedges or stakes. While handheld hammers rarely weigh more than four pounds, sledge hammers generally range in weight from six to twelve pounds. The head of the sledge hammer is usually fashioned from forged steel, and the handle is typically wood or fiberglass. In olden times, blacksmiths used the sledge hammer to forge metal.
