Morihei 9000 finishing stone

I found that the stone produces a fine slurry and helps put a good shine on the edge of the knives. It also doesn’t wear very much. I would recommend using one

Fantastic finishing stone

Best feeling finishing stone I've used. Edge still has a bite to it somehow. Great for cooking with a refined edge.
