A mattock is a versatile hand tool, used for digging and chopping, similar to the pickaxe. It has a long handle, and a stout head, which combines an axe blade and an adze (cutter mattock) or a pick and an adze (pick mattock). ==Description== A mattock has a shaft, typically made of wood, which is about long. The head comprises two ends, opposite each other, and separated by a central eye; a mattock head typically weighs .〔 The form of the head determines its identity and its use:〔 *The head of a pick mattock combines a pick and an adze. It is "one of the best tools for grubbing in hard soils and rocky terrain". The adze may be sharpened, but the pick rarely is; it is generally squared rather than beveled.〔 *The head of a cutter mattock combines an axe with an adze. Thus, it has two flat blades, facing away from each other, and one rotated 90° relative to the other. The blade is designed to be used for cutting through roots.〔 The handle of a mattock fits into the oval eye in the head, and is fixed by striking the head end of the handle against a solid surface, such as a tree stump, a rock or firm ground. The head end of the handle is tapered outwards, and the oval opening in the iron tool is similarly tapered so that the head will never fly off when in use. The mattock blade ought never be raised higher than the user's hands, so that it will not slide down and hit the user's hands. The mattock is meant for swinging between one's legs, as in digging a ditch with one foot on either side. Tapping the handle end on the ground while holding the head allows the handle to be removed.〔 In the eastern United States, mattock handles are often fitted with a screw below the head and parallel with it, to prevent the head slipping down the handle; in the western United States, where tools are more commonly dismantled for transport, this is rarely done.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「mattock」の詳細全文を読む スポンサード リンク
