A framing hammer is a large type of hammer used for heavy carpentry work, especially driving and removing large nails. Framing hammers are usually heavier than ripping or curved claw hammers, typically weighing from 20 to 32 ounces, and have longer handles. The extra weight and longer handle gives more power to the hammer's stroke. The head of the hammer is usually milled so that it has a crosshatch or wafflelike grid to prevent glancing blows. Since the frame of a finished house isn't seen, any marring of wood surfaces by the milled hammer face doesn't matter.
Framing hammers have increasingly been replaced by nail guns.
