The WAL-BOARD TOOLS 16 oz. Steel Drywall Hammer is made of forged, heat-treated steel to help ensure strength. The head of the hammer has a convex, serrated face to help set nails into ideal dimples without bruising or tearing drywall paper. The hardwood handle is off-set by 3-1/2 in. for knuckle clearance when setting nails in drywall.
