I bought a Craftsman belt sander. A 6 x 36 with a disc on the side stationary model. Use it to sharpen tools, sand wood, sand metal, remove fingernails. Small enough to take with you to job sites. Use it to curve ends of wood and metal. I don't use the disc much, but the belt part gets a work out. The curved top gets into a lot areas. A fine belt, 120-150 grit puts a quick edge on tools. For the record, I do hone with a stone, a good edge on wood chisels and the like, but I carry a couple chisels for "anything" that the edge is not critical on. Cutting wood on concrete, nails, aluminum, etc. For metal chisels it works great.
