The"Wood is Good"line of quiet mallets is guaranteed unbreakable. The heads are made of a tough urethane material designed to be quiet and yet able to transmit the maximum blow to the tool. The handles are beautifully turned out of selected, premiumNew England Hardwoods. They are polish sanded. Our mallets come in four popular weights of 12,18, 20, and 30 ounces. Both the 12 ounce and the 18 ounce mallets use our small urethane head of 2 3/4" diameter. The 20 ounce and 30 ounce mallets have a urethane head of 3 1/2" diameter.
