The wrapping is just plain old clear cellophane. Some has red stripes in the cellophane, and the others just plain clear. The first 2 I bought had some hand-written chinese writing on it, but the others only have the clear plastic stuck together with cellotape(scotch tape).
Those first 2 with the chinese hand-written paper in it was just the price, and shop details, nothing else.
Of what I can tell, but I'm not an expert, this does not seem to be the plain old Chinese 12K...it seems to be a different beast alltogether. I was able to hone razors from blunt, all the way to super smooth, starting with a slurry, and diluting it as I went along. The result was better than what I can get from my vintage Coticule, using the same technique.
Jimmy, I just checked my old PM's, and if I may, I will quote your last PM of the final result of this stone after your testing:
From Jimmy: "I don't know precisely how to categorize it grit wise but it is a real good hone. Yesterday and today I honed razors (Craftsman) with it and shaved. The razor I honed today was an old vintage Sta-Sharp (Sears & Roebuck) and I set the bevel with a 1200 DMT 8" then honed on the Chi hone with slurry diluting as I progressed. Finished with water at maybe 100 strokes ...... very light .....weight of the blade. HHT was effortless and the shave was smooth as silk and BBS. You've got a winner there."
