I'm getting a new belt grinder my 1x30 took it's last breath. Looking at belts there are alot of choices out there. What have you used and liked? I do know that I will be getting more than a few of the coarser belts as a belt grinder is very useful for many things. But this will mainly be a sharpener. I didn't have any of the very fine polishing belts for my 1x30. In fact I used the back of a worn belt and put green compound on it for my polishing. This time I'm looking at maybe a leather or plain cork. Truthfully my most used belts for sharpening on the 1x30 was a 600 and the back of the belt with compound on it. For regrinding a knife to a fully convex blade the real coarse belts made quick work of it, but I never did use them to sharpen. I think the coarsest I ever used for a chipped edge was probably a 320, or 220. So, what do you use? What have you used and not liked? If you were doing it all over again what would you get?
