Course water stone.

Thankyou to Jay for recommending the Beston 500. I think that's the way I'm giong to go. I think I may have led people down the path by mentioning flattening. The only thing I have to flatten is a small set of Koyamaichi chisels from Stu which will hopefully be arriving soon, but I'm assuming the hollow on the backs of the chisels will make this a small chore. There will be no flattening of vintage chisels or plane irons in my future. Been there, hated that.

you can flatten the Koyamaichi chisels on a 4000grit water stone.... they are very well made and the hollow makes it a non issue. basically just polish the back a little and they are good to go.
