So lowder,

When you say "thinning an edge out", what exactly are you talking about doing?

I made a few pocket knife kits using mostly Dremel gear. I considered buying a belt sander of some kind to work handles and blades. I did not do it mostly because I determined that the kit parts were not going to produce the results I wanted. I have a couple small belts that fit on my Inca band saw and I have been
revisiting the idea of buying a "real" belt sander for: wood working chores, sharpening/cleaning/regrinding mower blades, polishing... Maybe a belt sander is in my future.
