Due to it's poor condition there has been some argument about the owner of the hand holding the knife (or, as some call it, - a dagger):

The theories are:
- The hand belongs to John/Mary (whoever you choose to believe they are). Peter is holding his/her wrist. Andrew, who sees this, is horrified at this.
- The hand belongs to a separate, obscured person, probably John, with Mary shown at the right.
- The hand holding the knife belongs to Peter - he has it twisted backwards away from Judas
Let's look at each theory in turn:- Here's an image which has been doctored to remove Judas. Notice anything odd?

If that knife is being held by John/Mary then he/she has arms like a gorilla! Would Leonardo have made a mistake like this? There's also the evidence of John/Mary's fingers intertwined in front of him/her!

This suggestion assumes that the feminine figure at the right in the image is Mary Magdalene. In that case John, the youngest of the disciples is missing. The idea is that the hand belongs to John who is obscured by Peter and Judas. I find this very unlikely. If it were true - where exactly would John be?
Maybe he dropped his glass?
The last suggestion is that Peter is holding the knife at a very odd angle. The 'copies' suggest that this is the case and so too does this sketch by Leonardo - clearly that knife in the hand of Peter gave him some problems and he decided to practice.
