I believe it is the transfer of the knife into the space occupied by the torso and the intent to do so that is illegal. If the torso moves into the space occupied by the knife on its own, it’s an unfortunate accident. If the torso moves into the space intentionally, it is self-harm or suicide depending on outcome and where the knofe intersects the torso.
