In reply to woody0606:
Offsets are a little prone to kinking and snapping strands, at least my old HB ones are when removed by yanking. Nutkey is pretty much essential.
As for the broken wires, it's not ideal obviously and you have to choose how much risk you're willing to take. Personally I still use and trust mine (various nuts) with a few broken strands, it's a fact of life with well used old gear. Thinner wires (micros mostly) would go in the bin if I broke strands.
One thing to watch for is getting the broken bits stuck in your fingers, lips or tongue. Not a lot of fun!
