Boldy go forth! If you have the nerve, get one of these for about $45 from Harbor Freight. It is a 1" X 30" belt sander. Remove the adjustable tool rest, belt guide and safety guard. You must do this to have room to put big blades in the slack part of the belt midway between the wheels. You may be changing belts often, so it is easier to leave the cover off, too. Do wear eye protecton, a piece of hot steel in your eye will ruin your day. Practice on a cheap kukri or machete(an excuse to buy more knives) until you can do a nice convex edge. This is all done free hand, without rests or guides. For serious stock removal use 80 grit. I like 180 grit for sharpening a dull knife. I used 400 to touch up DF. Try to adjust belt tension as loose as possible and still stay on the rollers. This is not for the faint of heart. You can screw up an edge if you're not good at free hand sharpening. This thing will remove metal in a hurry. I use a steel, diamond rod, or ceramic rod for most touch ups.
