Surface conditioning belts are cool! I've made some beautiful satin finishes by using a coarse belt for depth and then finishing with a fine grit belt belt for a smooth satin feel finish. That type of finish adds grip and also resists fingerprints.
Using conditioning belts, it's possible to create some freaky optical delusions. Check out this thing that I did on stainless tubing. When the light hits it, it appears to be horribly bent and askew as though it was run over by a truck. Actually it's perfectly, absolutely straight.
I did it by grinding each of the the tubing segments at opposing 45° angles. Using a clock face for reference, from left to right the top half is ground from 8:00 to 2:00 and the next lower section is ground from 10:00 to 4:00 and so on. Even under close examination the illusion delusion confusion conclusion of the mind's eye persists!
Who knew abrasive belts could be so much fun? It would be fun to do that on a knife blade. Awww... too bad your nice knife got all bent up dude!
