Nakayama narrow tomae #712 This narrow stone can take a razor from bevel set to shave ready if you use a slurry to clear water method, no problem. It is only moderately hard and the grit is super fine. As a hand held or a bench stone it is perfect for X strokes or for focusing in on a problem area of and edge. The brown yaki areas are not toxic in anyway and there are no inclusions. The toishi has been lapped perfectly flat, the sides dressed and the corners and edges beveled unless otherwise noted.  All of my stones come with a money back guarantee minus the shipping.
