Probably the most widely used type of hammer, the Estwing claw framing hammer, were developed specifically for carpentry jobs. Claw hammers combine a striking head for driving nails with a rear-facing claw for pulling out nails. Estwing Claw framing hammers range from 22 oz to 30 oz. with longer handles and heavier, either milled faced or smooth faced heads to deliver the pounding force necessary for driving big nails. These hammers are specifically designed to be used in framing and wood frame construction projects.
