Good thinking, Randy. Sadly, my bar shear blades aren't reversible. The
angle shear blades are, though.

I think I'm going to try sharpening these blades. I don't see what I
have to lose.

You might want to stop by your local printer
and ask him where he gets his blades sharpened
and how much it costs.

Printers have great big shears for stacks of
paper and have to get the blades sharpened
regularly.
