No no I did understand ^^ I just think it would be nicer if you saw the cut open along the blade (something like in Trauma Center for instance)
Oh definitely get what you say, actually it was my first idea but I really couldn't get unity to do what I wanted. And there isn't really tutorials for what I wanted to do. This might be much to ask but if you know any tutorials for that I will gladly take it. ( I will check the Trauma Center as well)
