Abstract

　剃刀刃の刃先２において、基板３の両表面７，８にはＴｉ、Ａｌ、及びＣｒを含む非窒化層９が被覆層４の一部として形成され、その非窒化層９の両表面１０，１１にはＴｉ、Ａｌ、Ｃｒ、及びＮを含む残存層１５が被覆層４の窒化層１２の一部として形成され、その残存層１５の両表面１６，１７にはＴｉ、Ａｌ、Ｃｒ、及びＮを含む表側層１８が被覆層４の窒化層１２の一部として形成され、その表側層１８の両表面１９，２０にはフッ素樹脂層６がＣｒやＡｌ等を含む接合層５を介して形成されている。非窒化層９と窒化層１２とを備えた被覆層４により、刃先２をより一層改善し、刃先２の切れ味を良くするとともに、その切れ味を維持して耐久性を向上させることができる。
