If you don't care that it doesn't look stock, why do you want it reblasted to look stock?
Maybe you bought one that had been rubbed down for a song on the MP and want it to be blasted again but don't care about the edges? Maybe you decided it was too slippery. Maybe it was a gift. There's plenty of possible scenarios. I'm assuming it would be more a grip thing than a looks thing as you wouldn't scotchbrite it if you were paranoid about the look.
