Eel, that 1"X30" sander from Harbor freight would work as well. Get belts in the following grits, 100, 220, 400, 600, and a crotous belt. Use the 100 grit for putting on a new profile, otherwise start with the 220 grit. The crotous belt is a ultra smooth polishing belt. You load it up with polishing compound and use it as the final honing belt.
Using the belt system is a far faster way to sharpen ultra hard steel knives that are in the 59-61 RC area of hardness. A lot of my customers will put that razor edge on their knives and be able to dress out 2-3 deer or elk and not have to touch up the edge until getting back home.
Just remember a light pressure is all that is needed when using the belt system of sharpening. You are not trying to hog out a large amount of steel.
