yeah I checked my new one and cant tell. I remember speaking with the propshop guys at comic con this year and they mentioned that some of the parts were vacuumed metalized, which might be the case for the "claw" but not sure. Does anyone have any suggestions on how I could test it? Magnets?
Aluminum is non-magnetic for the most part, so a magnet won't do it. Besides tapping it, you can touch a part of the hilt you know to be metal to your lips, and then compare the coldness to that of one of the vertical pommel fins. I don't think there's any other way to test it that wouldn't damage it.
