a few days ago I wore out my cheap eden 240 grit stone from thinning and sharpening. now I need another coarse stone. I want a stone that does not dish too fast. I would like to stay under 50 dollar. i'm thinking of a naniwa chosera 400 or naniwa ss 400. how would you compare them or do you have other recommendations?
(ps I would like to buy in europe to save on shipping costs.
