[QUOTE=You must have single Norton grits rather than the combo stones. I liked that idea when I had my Norton combo, but buying a single 4000 and a single 8000 were out of my price range at the time. There's a place called toolsforworkingwood.com that sells single grit Nortons rip sawn lengthwise into 8"x1.5"x1" for half the price. I thought about buying those for narrow hones but haven't yet.[/QUOTE]

You're right. I liked the price of the combo stone but the ability to hone on the narrow side, and the fact that they will last much longer, won me over to the single stones. I absolutely don't regret it.
