Holding the box cutter. June 3rd, 2016.

The box cutter is a weapon in Yandere Simulator.


In the game, the box cutter was found by the school entrance for debugging purposes, but was relocated to the Art Club in the November 15th, 2016 Build.[1] The box cutter can be concealed and is not seen as suspicious, so Ayano's reputation will not be damaged if she is seen carrying one.


If the player grabs a cardboard box from the Incinerator area, covers it with masking tape obtained from the Art Club, and inserts a box cutter while wearing gloves, they can ask any student, excluding the Student Council and Delinquents, to remove the box cutter for them. This will get said student's fingerprints on the item. Therefore, if Ayano commits murder with the box cutter with another student's fingerprints and disposes of the gloves and uniform, that student will essentially be framed for murder, and then be arrested.

Box Cutter Animations

There are 4 killing animations of Ayano's level of sanity.

  • High Sanity: Smooth stab to the right side of the head.
  • Medium Sanity: The victim tries to defend themselves, then sloppily gets stabbed in the right shoulder by her; then they are stabbed in the right side of the head.
  • Low Sanity: She will grab the victim's neck and tackle them to the ground; the victim will try to defend themselves as they are stabbed in the head multiple times. If you mash the attack key (F) the animation will loop until you stop mashing it.
  • Stealth Kill: She will cover the victim's mouth, then she will stab them in the side of the head.
