En '''barberkniv''', også kalt '''rakekniv''', er en meget skarp spesialkniv til [[Barbering|våt-]], av og til også til [[Barbering|tørrbarbering]].

Den består av et avlangt [[stål]]blad (vanligst er 16mm vidde<ref name="The-Straight-Razor-Shave">[http://www.shavemyface.com/downloads/The-Straight-Razor-Shave.pdf The-Straight-Razor-Shave]</ref>) som kan foldes inni et håndtak. Bladet er som oftest laget av ikke-rustfritt såkalt AHSS-stål med hulslipt egg. Håndtaket er laget av tre, horn, [[perlemor]], [[bakelitt]], [[celluloid]], skilpadde eller [[plast]]. Slike barberkniver var dominerende i det [[19. århundre]].

Til forskjell fra en barberhøvel, pådrar man seg ingen ytterlige kostnader ved anskaffelse av en barberkniv. I tillegg gir den visstnok grundigere barbering.<ref>Ray A.
