Pincers are a hand tool used in many situations where a mechanical advantage is required to pinch, cut or pull an object. Pincers are first-class levers, but differ from pliers in that the concentration of force is either to a point, or to an edge perpendicular to the length of the tool. This allows pincers to be brought close to a surface, as is often required when working with nails. If the pincers have perpendicular cutting edges, the pincers are often called end-nippers or end-cutters. Carpenter's pincers are particularly suited to these tasks. Pincers are primarily used for removing objects out of a material that they have been previously applied to. Pincers, often red-hot, have been used as an instrument of torture〔(Example of the use of pincers for torture in mediaeval Italy )〕 since ancient Roman times or earlier. Pliers are a similar tool with a different type of head used for squeezing, rather than cutting and pulling. == References == 〔 pt:Turquesa (ferramenta) 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「Pincers (tool)」の詳細全文を読む スポンサード リンク
