Cannot recommend this enough. I posted a thread a while back about which "power" tool to buy for sharpening. I was going to get the paper wheels until I discovered my bench grinder was a 3450 RPM unit. I didn't want to buy a second grinder so I opted for the Kalamazoo instead. I use a 220 belt and then a leather belt with white compound. In less than one minute a knife is shaving sharp. I even did my hatchet and ax....also shaving sharp in a minute or less. This thing is incredible. Although hand sharpening is a great skill to have I wasted A LOT of hours fiddling with stones, the sharpmaker, edgepro, sandpaper, etc..I wish I have bought this years ago. Seriously it is worth every penny and more.
