来自古英语cnif,刀,匕首。也许你会问,为什么用餐刀子是圆头的呢?这要归功于法国政治家及红衣主教黎希留(Richelieu,1585-1642)。过去的餐用刀子都是尖头的。有一次宴会上,黎希留看见他的一位客人拿刀尖儿剔牙,他大为恼火,觉得伤了他的大雅,于是第二天就命令管家把所有的刀尖儿都给锉圆了。到了大约17年时,这种圆头儿的刀子开始普遍受到人们的欢迎,直到今天。=Knife一词在古英语中写作cnif。

小知识
A knife is a sharp tool that's used for slicing or cutting. We suggest using a knife as a kitchen tool instead of as a weapon.
A bread knife has a long, serrated edge, and the blade of a pocket knife folds into its handle so you can safely carry it in your pocket. Surgeons use very small knives to make delicate cuts during operations, and various kinds of knives are sometimes used as weapons. To knife, in fact, is to stab or cut with a knife, almost always in a violent way.
