U+5240 "剀" CJK Unified Ideograph-# Unicode Character

Unicode Version 17.0

U+5240 "剀" CJK Unified Ideograph-# is a Chinese character (hanzi) that primarily conveys the abstract meaning of "cutting" or "carving," and is often used in classical texts or compound words related to sharpness, engraving, or the act of incising. It belongs to the set of unified CJK ideographs used in Chinese, Japanese, and Korean writing systems, and its structure combines the radical for "knife" (刂) with the phonetic component "开" (kai), which provides a hint to its pronunciation in Mandarin as kǎi. While not a common everyday character in modern Chinese, it appears in historical literature and specialized contexts, such as describing the meticulous engraving of stone or metal, and it may occasionally be encountered in personal names or classical poetry.
