I would drop them from a height of 3 feet onto a concrete floor, and see how they break, so that I know to never drop good ones in the future if I get them. There is absolutley nothing else to do with them.
Out here in the perimeter we is stoned, immaculate.
they actually break really easily. back when I had my variocam designed, the cam maker threw my cams in 4 thin cardboard boxes and sent them via ups... one of them was broken in half. it's how I ended up with billet cams the 1st time around
