Claw hammers are the most common types of hammers used for woodworking and general repairs around the home. They are available with different types of handles, wood as shown, steel with rubber or plastic grips and fiberglass composition. The style of hammer you select should be a personal decision, hold the hammer in your hand as if to strike a nail, it should feel balanced, the grip should be confortable. There are different weights, 16 ounces is a good general purpose choice, for heavier work perhaps 20 ounces. Smaller weights are suitable for tacks and light work or children.
