Yeah, this will actually be my 3rd coti added to the collection. I feel pretty confident honing on the coti's and use one as my go to "troubled razor" hone. I was just wondering who might have made this stone. I grabbed it because it was vintage and cheaper than buying the comparable size new. Hopefully, it's a good stone for razors. I'm hoping a get coti gold and this bad boy outdoes my two others.
