I've always imagined that "Claw" became a local nick-name rather than something he called himself. He might have indeed changed his name but Demetrios never appeared to have much of a sense of humour. Imagine chopping your own leg off by accident and asking people to call you Peg Leg or Stumps.
(Something else I mentioned in another thread is that the actor, Vic Tablian, seems to have broken his nose sometime between filming "Raiders" and the YIJC stuff.)
