The sledgehammer can apply moreimpulse than other hammers, due to its large size. Along with themallet , it shares the ability to distribute force over a wide area. This is in contrast to other types ofhammer , which concentrate force in a relatively small area.Uses
The handle is typically half-a-meter to a full meter longFact|date=June 2007; the head mass is usually one to three kilograms. Sledgehammers usually require two hands and a swinging motion involving the entire
torso , in contrast to smallerhammer s used for driving in nails. The combination of a long swinging range, and heavy head, increase the force of the resulting impact.Sledgehammers are often used in construction work, for breaking through
drywall ormasonry wall s. Sledgehammers are also used when substantial force is necessary to dislodge a trapped object (often infarm oroil field work). Another common use is for driving fence posts into the ground. Sledgehammers were often, and, to the present day, are, used by police forces in raids on property to gain entry by force, commonly through doors.Another iconic use of sledgehammers is for driving railroad spikes into the ground during rail construction. When the two ends of the
Union Pacific railroad were joined atPromontory, Utah ,Leland Stanford hammered agolden spike into a tie with a silver hammer.In the United States, 10- and 20-pound sledgehammers are common.
