Cutting fetish, or cutting kink, is a term for a sexual interest in cutting to draw blood. People with a cutting fetish may fantasize about cutting themselves and/or sexual partners, or they may act these fantasies out.
People with a cutting fetish may use a range of instruments, including knives and razor blades. As those with a cutting fetish most often wish to draw blood, a cutting fetish is often related to a blood fetish. However, cutting fetish isn't the same as cutting; the goal is not self harm but sexual gratification. Cutting can also be considered a from of sadism or edgeplay, one that is used in BDSM play and scenes.
Cutting fetish is also known as piquerism.
