I think I have a knife kink

Never tried this, but I like the idea of someone dragging the dull end of a knife against my naked body. I don’t wanna get cut and I only wanna try it with someone I really trust. I think I love the principle of the fact that I feel safe with a knife against me because it’s being controlled by someone I love/trust while also still getting the adrenaline rush. Wouldn’t mind getting a lil spank from it either. I also have long hair so running it through my hair would be hot. I think it would be a thrilling yet comforting experience.
