Just for the heck of it, checked Knife Center for Norton India stones. They have the 6" benchstone, both medium/fine for $20. Just recently re-read something by Wayne Goddard. He said the fine Norton is excellent, but he doesn't care for the others. Believe Ed Fowler said something similar sometime. Course, those guys have grinders etc to do the rough work.
Lots of things make me feel inadequate to a degree. Ed Fowler re-sharpening a blade he has just purposely blunted on a Norton India fine stone went near the top. Something like 2-3 swipes per side, and super sharp. Think it must be like riding a unicycle or something.
