The difference in the faces stops the panel surface being marked with the edge of the hammer when used in conjunction with the dolly block. The weight of the planishing hammer for general and new work ranges from 12 oz (340 g) to 16 oz (450 g), and the handles, which are usually very thin at the neck of the shaft for balance purposes, are made of hickory or ash to give the hammer a good rebound action when used with a dolly block.
