Reminds me of something a friend of mine was talking about. He's really into making chainmail and is in contact with others of the trade. Supposedly one got a hold of enough titanium wire that he fashioned a titanium chain shirt and shot it with a shotgun slug at close range... popped one of the rivets that was made of steel.
Of course, this brings to mind that the majority of suits, including very fine chain, could be made from adamant... It would just be a very long and tedious process. And would require nontraditional methods to do so.
