![]() Hammers used in many trades include sledgehammers, mallets, and ball-peen hammers. Other types of hammers vary in shape, size, and structure, depending on their purposes. Ubiquitous in framing, the claw hammer has a "claw" to pull nails out of wood, and is commonly found in an inventory of household tools in North America. ![]() The modern hammer head is typically made of steel which has been heat treated for hardness, and the handle (also known as a haft or helve) is typically made of wood or plastic. ![]() Use of hammers and heavy mallets for demolition must adapt the hammer stroke to the location and orientation of the target, which can necessitate a clubbing or golfing motion with a two-handed grip. Small mallets can be swung from the wrists in a smaller motion permitting a much higher cadence of repeated strikes. War hammers are often wielded in non-vertical planes of motion, with a far greater share of energy input provided from the legs and hips, which can also include a lunging motion, especially against moving targets. Carpentry and blacksmithing hammers are generally wielded from a stationary stance against a stationary target as gripped and propelled with one arm, in a lengthy downward planar arc-downward to add kinetic energy to the impact-pivoting mainly around the shoulder and elbow, with a small but brisk wrist rotation shortly before impact for extreme impact, concurrent motions of the torso and knee can lower the shoulder joint during the swing to further increase the length of the swing arc (but this is tiring). Hammering is use of a hammer in its strike capacity, as opposed to prying with a secondary claw or grappling with a secondary hook. Traditional disciplines include carpentry, blacksmithing, warfare, and percussive musicianship (as with a gong). Hammers are used for a wide range of driving, shaping, breaking and non-destructive striking applications. This can be, for example, to drive nails into wood, to shape metal (as with a forge), or to crush rock. ![]() For other uses, see Hammer (disambiguation).Ī modern claw hammer suited to drive and remove nails Cartwheel mallets with heads of felt held between steel washers for use with timpani drums Detail of the head of a war hammer A geologist's hammer used to break up rocks, as seen in archaeology and prospectingĪ hammer is a tool, most often a hand tool, consisting of a weighted "head" fixed to a long handle that is swung to deliver an impact to a small area of an object. ![]()
