剃刀

Compound of 髪 (kami, “hair on the head”) +‎ 剃り (sori, “shaving facial hair or body hair; a shaver”, the 連(れん)用(よう)形(けい) (ren'yōkei, “stem or continuative form”) of the verb 剃(そ)る (soru, “to shave facial hair or body hair”).). First cited in the ten-volume Wamyō Ruijushō of 934 CE.^[1]

The kanji are from Chinese 剃刀 (tìdāo).
