Re: tungsten carbide magnetic?

George,

I got them off of ebay from the seller "emovendo",
but they weren't cheap. Like $150 each, I believe.
Also, if they ever come in contact with one another
with any part of your body in between, like your
fingers, for instance, you WILL be in a pickle and
you WILL chip the magnets at their contact points!
Ask me how I know this 8^0 I smashed my finger tips
pretty good just slipping my fingers out from between
them! They were pretty darn sore for the next few days
and I consider myself fortunate that I wasn't injured
any worse than that! NFeB mags of this magnitude are
indeed dangerous.
