I have a Grizzly metal cutting band saw, the kind you can lay down or stand up. I use their bi-metal 18 tooth blades. It seems to work well.
I am working with some Rex M3-1 right now. It looks to be a real tough one too. Working hardness of 62 Rc when your all done quenching from 2100 deg and tempering 3X at 575 deg or so. I imagine it won't polish either.
