In reply to:

a MK2 is stainless steel of unknown hardness but i don't imagine it being anything too excotic and the MK2As are actually a mild steel with a brushed stainless finish




I would have to disagree. The manual for my RioCar says the case is stainless steel. Aren't all RioCars MK2As? Unless the manual is in error, would this not disprove the above statement? My rare earth magents are hardly interested in the case at all. If it were truly mild steel, they should have held on tight.

Anyway, the case wasn't too hard to drill or file, so I don't think that a die for the knock out cutters would be too hard to make.
