<P> Foot adzes are most commonly known as shipbuilder's or carpenter's adzes . They range in size from 00 to 5 being 3 1 / 4 to 4 3 / 4 pounds (1.5--2.2 kg) with the cutting edge 3 to 4 1 / 2 inches (75--115 mm) wide . On the modern, steel adze the cutting edge may be flat for smoothing work to very rounded for hollowing work such as bowls, gutters and canoes . The shoulders or sides of an adze may be curved called a lipped adze, used for notching . The end away from the cutting edge is called the pole and be of different shapes, generally flat or a pin pole . </P> <Ul> <Li> Carpenter's adze - A heavy adze, often with very steep curves, and a very heavy, blunt pole . The weight of this adze makes it unsuitable for sustained overhead adzing . <Ul> <Li> Railroad adze - A carpenter's adze which had its bit extended in an effort to limit the breaking of handles when shaping railroad ties (railway sleepers). Early examples in New England began showing up approximately in the 1940s--1950s . The initial prototypes clearly showed a weld where the extension was attached . </Li> </Ul> </Li> <Li> Shipwright's adze - A lighter, and more versatile adze than the carpenter's adze . This was designed to be used in a variety of positions, including overhead, as well as in front on waist and chest level . <Ul> <Li> Lipped shipwright's adze - A variation of the shipwright's adze . It features a wider than normal bit, whose outside edges are sharply turned up, so that when gazing directly down the adze, from bit to eye, the cutting edge resembles an extremely wide and often very flat U . This adze was mainly used for shaping cross grain, such as for joining planks . </Li> </Ul> </Li> <Li> Another group of adzes can be differentiated by the handles; the D - handled adzes have a handle where the hand can be wrapped around the D, close to the bit . These adzes closely follow traditional forms in that the bit or tooth is not wrapped around the handle as a head . </Li> <Li> The head of an ice axe typically possesses an adze for chopping rough steps in ice . </Li> <Li> A firefighter tool called the Halligan bar has a dull adze on one end of the bar . This bar is a multipurpose tool for forcible entry of a structure and demolition with a forked pry - bar on one end and an adze and spike on the other, called the adze - end . </Li> <Li> Demolition adze - A demolition adze has a dull edge and is used for separating materials in the demolition or salvage of old buildings . </Li> </Ul> <Li> Carpenter's adze - A heavy adze, often with very steep curves, and a very heavy, blunt pole .
