刀（dāo）
刀（dāo）
字形：
古体"刀"字像有柄的刀型，是一种兵器，后泛指斩、切用的工具。汉字中以"刀"为偏旁的字，都与刀的功用有关，后来也把功用不同的各种有刃工具称为"刀"，如剪刀、剃须刀。
The ancient form of the character "刀" was the image of a short-handled, back-arched knife. It was originally a weapon, and later used as a chopping and cutting utensil. The Chinese characters with "刀" as their radicals all carry the meaning of or have the function of a knife. Later, various edge tools with different functions were all called "刀", such as "剪刀" (scissors) and "剃须刀" (razors).
