'Affordable' 8000 grit stone
Deciding that honing is something i want to become profecient at (i enjoy sharpening blades of all kinds) i'm looking for an 8000 grit stone. However the prices are incredible ! I picked up a Japanese combi-stone (1000 & 6000) and nagura for £30 a few years back. I don't begrudge paying that sort of money for what is, essentially, 'a stone'.
However looking at prices for an 8000 the price really rockets. The absolute cheapest i can find is about £50 not including shipping. Is there really no cheaper alternative ?
