Knife play involves using knives in BDSM scenes, typically for psychological effect and light sensation rather than cutting. The visual and psychological impact of a blade creates intense scenes.
Most knife play involves running blades over skin without cutting, using the flat or back of blades, or simply the presence and threat of the knife. The fear response creates adrenaline and intensity.
Blood play involving actual cutting exists but is extreme edge play with serious risks including infection, scarring, and going too deep. Most knife play doesn't involve breaking skin.
Safety involves using appropriate knives (some prefer dulled blades for safety), understanding anatomy, never playing impaired, and having first aid available.
