Skull and crossbones.png Edge play is dangerous; do not try this at home! Skull and crossbones.png

Knifeplay is generally a form of fear play, sensation play and light medical play if it involves making scratches and abrasions, though generally speaking knifeplay does not involve branding or cutting unless it is explicitly discussed as part of negotiations.

Knifeplay often involves moving a blade across sensitive portions of the skin, threatening safety with a knife, clothing removal with a knife and minor scratches and abrasions that might result from light pressing the blade to the skin.

Best Practices

  • Discuss the topics of edge play and RACK, as well as the potential for marks and minor cuts.
  • Discuss if knives are a psychological trigger, or if touching a specific area with a knife is a psychological trigger, or if menacing with a knife is a psychological trigger.
  • Discuss if either possesses any Bloodborne Pathogens or STIs.
  • Discuss if the scene is intended to incorporate advanced techniques such as cold, heat, fire, electricity, cutting, branding, scarification and similar.
  • Equipment is cleaned, sanitized and laid out in a safe manner so that it won't accidentally cut or impale someone during an accidental fall.
  • The concept and title of edge play is derived specifically from the idea that knives are sharp and very dangerous; respect the power and danger of the blade. Be sure you have practiced your control to a point where you are comfortable placing a knife on and running it along your own sensitive bits long before you ever place a knife on the skin of another. Actual knife play is even more dangerous than this because your partner may move, jump or sneeze unexpectedly and you are required to react without notice for their safety.
  • If this is the first time the bottom has experienced knife play, test their reactions with the blindfold and bondage technique before utilizing a sharp edge on their skin.



After you have completed negotiations consider experimenting with some techniques after having practicing them on your own.

==== Butterfly Flourish ==== the butterfly flourish is a technique utilizing a butterfly knife in which the knife is brandished and flipped open in a flashy and potentially intimidating manner if coupled with a predatory grin and piercing gaze. [1]

  • Blindfold and bondage This is a bait and switch technique done for safety. Place your partner in secure bondage that helps prevent them from wiggling much such as being firmly wrapped in several places to a table, pole or back board. Show them the knife so that they are aware of what is about to be done to them and then place a blindfold on the partner.

Without the partner's awareness change the sharp blade for either the dull side of a blade, a chilled metal dull blade or an electrified metal dull blade.

Utilize the new tool and run it across the skin of the bottom utilizing any psychological word play you may have prepared, often a well placed "Don't Move" whispered in the ear is effective. This will test the reaction to the "knife" to see if they jump or squirm in fear while thinking they are in danger. In the case that they do jump or squirm they will not be sliced open and will be relatively safe because of the use of the dull implement. At worst in most cases they might have a dull pain from a poke of the tip of the object, which is far better than a trip to the emergency room.

When you are comfortable you may change out the tool for the knife blade to operate on your partner. You may or may not decide to show them that you faked them out with the dull tool depending on what you'd like to achieve.

Unless you are incorporating various dangerous elements like cutting, branding, fire or electricity, knife play is mostly psychological and fear based. Attempt to capitalize on the intention of the scene by imagining and fantasizing a scenario in which you are truly afraid of the knife.
