I too don't know if a guy could dull one cutting brass but, what you could do is see a saw/knife sharpener and have them touch it up. Or, if you have a machinist handy they could probably do the same on a mill.
I know that Ken at K&M Products sells the replacement cutters. I've spoken w/ him a couple of times and he is very nice to deal with! Don't know how much they are though. He has a little pamphlet with the turners & priming seating tools & other stuff as well. Sam
K&M will resharpen your cutter. I sent three cutters to Ken to resharpen and I think it was under 7 bucks. I bought three used K&M turnes at the Super Shoot two years ago for $100 and didn't know how much they were used.
