U+921A "鈚" CJK Unified Ideograph-# Unicode Character
U+921A "鈚" CJK Unified Ideograph-# is a rare or historical Chinese character that refers to a type of arrowhead or a sharp cutting tool, often associated with ancient weaponry or metalwork. Its structure combines the radical for metal (金) with the phonetic component “比,” suggesting both its material composition and a possible relationship to the concept of comparison or pairing. This character is not commonly used in modern Chinese or Japanese writing, but it appears in classical texts and specialized dictionaries, particularly those documenting archaic or technical terms related to traditional Chinese arms and armor. Due to its obscurity, it may not be supported by all fonts or digital systems, making it a subject of interest for scholars of historical linguistics and paleography.
