I got mine from woodcraft a few days ago. Put very nice edges on everything I ran it through. Belt moves rather slowly, so there's hardly any heat buildup. Does well with scissors.
I love this thing because it's become much more than a sharpener to me. It's a baby belt grinder, and it's such a fun little toy for me. Gives me a break from my big grinders. Tonight, I did some shaping up on the edges of a kydex sheath, and it did a beautiful job. I'm going to take one of the worn 6000 grit belts and load it with some Flitz, green chrome or white matchless. I bet that would make for some awesome power stropping.
I hardly use the guides anymore. I was thinking about making a tiny little platen for it....lol. I can use the platen on the right side, and the opposite side can still be slack since it runs away from the edge.
At this point, It's not a sharpener to me. It's a very versatile little tool for knifemaking. I can employ this thing in thousands of ways. Time to make a platen!
