About
The character 锉 is a phono-semantic compound with the semantic radical 钅 (jīn, metal) on the left and the phonetic component 坐 (zuò, to sit) on the right. Its traditional form 銼 uses the full metal radical 金. The character primarily means a file, a hand tool with a rough surface for abrading or shaping materials like metal, wood, or bone. It also functions as a verb, describing the action of filing, grinding, or wearing down a surface to smooth or sharpen it.
