EDIT: Changed image hosts, so there are no nasty popups...
I found this stone at a flea market kind of place with lots of cheap stuff. It's 8" x 2" x 1", and is darkish blue on the outside. I noticed some that had chips missing and they were gray to dirty white where the chips are, so the blue is only "skin deep". It also left blue dust on my fingers when I tested the stone with my fingernail. I'd estimate it's around 150 grit or so. I think it's probably a coarse aluminum oxide stone, but I don't have enough experience to be sure. It feels around the same roughness as my medium silicon carbide stone.
It says something like DianHao Whetstone Germany on the label. If you look at the picture, the first character seems to be a stylized "d", but I'm not sure. Google searches turn up nothing for this.
Oh I forgot: The price! $0.99 plus tax. I should have just bought one, but I'd rather not throw a dollar bill out the window if this is complete junk.
I also suspect this stone is made in China due to the name, but who knows.
Should I be concerned about the blue coating wearing or chipping off? Is it just cosmetic, or does it somehow have different abrasive properties than the rest of the stone? Is it likely to be complete junk and dish or wear funny or simply be uneven in texture? In short, waste of money, or bargain of the century?
