Yes, the wheels are what I had before. They were pretty effective, and yes, I could get knives sharp enough to whittle hair. Not entirely portable, but it got used a lot. It would make a ribbon on the edge if you weren't careful. I ruined a few small blades before I got the hang of it. It is really easy to overdo it.

The deal with the work sharp is the belt speed is not too high. 3400 rpm seems a bit hot and I might worry a bit about destroying the heat treatment on a blade. As with all things, I suppose it just takes some practice to be proficient.

I wish I could've mastered freehand with stones. It just never worked out like I wanted.
