Mr. Mark sayeth, "IMHO, ultra premium belts really aren't necessary for sharpening. Normally these heavy duty belts are made for high rate of removal using heavy pressure. They last a long time under these conditions, which is why they are so expensive and only available in coarse grits."
The Cubitrons weren't that expensive ($2 - $3 as I remember), work great and seem to last forever. But yeah, they are meant for high pressure grinding. As I understand it, the pressure fractures the crystals and keeps the belt sharp. I suspect if mine starts to get smooth I can lay into it with some hard steel against the platen to crack some crystals and it will be good to go again. (Just a guess).
I've used 180 grit Deer's but didn't like them as much as the 150 Cubitrons and they didn't last as long either.
I have some 120 grit Cutitron II belts, but the last time I tried them they were a bit on the aggressive side. Have to try them again and use one enough to break it in.
Oh well, it's kind of a moot point now. I'll have to try Blaze or some other ceramics and find a substitute.
