The kanji 錘 is a phono-semantic compound (形声文字 - keisei moji). It combines the radical 钅 (金 - kin), meaning "metal," with the phonetic component 垂 (sui), which contributes the sound and suggests the idea of "hanging down." This combination reflects the character's meaning, as weights are often made of metal and are designed to hang downwards. The original form of the character might have depicted a weight hanging from a string.
