A nutcracker is a tool designed to open nuts by cracking their shells. They are made in many styles, with a particularly well-known type portraying a person whose mouth forms the jaws of the nutcracker. ==Functional== Manufacturers produce modern nutcrackers—designed to crack nuts—usually somewhat resembling pliers, but with the pivot point at the end beyond the nut, rather than in the middle. The spring-jointed nutcracker was patented by Henry Quackenbush in 1913. These are also used for cracking the shells of crab and lobster to make the meat inside available for eating. Nuts have long been a popular choice for desserts, particularly throughout Europe. The nutcrackers were placed on dining tables to serve as a fun and entertaining center of conversation while diners awaited their final course. At one time, nutcrackers were actually made of metals such as brass, and it wasn't until maller birds crack seeds. In this case, the pivot point stands opposite the nut, at the jaw. Some artists, among them the multi-instrumentalist Mike Oldfield, have used the sound nutcrackers make in music. Nutcrackers have also been used as a token of good luck and goodwill to protect people from evil spirits and danger. They were thought to bare their teeth at any evil spirits to scare them away, just like a guard dog might do. 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「nutcracker」の詳細全文を読む スポンサード リンク
