Thread: Another new stone, please id

There is no writing on the stone. I will do a dulicot tonight and post the impressions.

To tell you the truth just looking at that edge where you can see an unweathered part that really looks an awful lot to me like solid garnet. Not the whole piece just in the 5th photo those 3 areas.

Unbacked vintage Coticules are not that rare, I had 6 of them out of about 18 vintage Coticules I bought. They're all backed now with slate I cut from a tile. I think the 'layering' you see are just different angles in the sides.

Is the shininess of the unlapped sides just the patina of use, or could someone have varnished them?

Send some of the slurry to Holli4pirating. He'll be able to tell from the taste.

Is a coticule. I did dilucot on two razors , last night and is a coticule. It a fast on slurry and bring an very nice edge on water only. Water start to have black steel swarf after 10 -15 strokes, but not autoslurry.I get HHT2-3 on both razors, and 4 after stropping. So treat it like a coticule and is a coticule. What are your toughts, live it in this condition, or round the sides?You think the opposite side may be a hybrid?

I lapped the other side and in the middle,is something like marble, and it can't be lapped flat. Is like some inclusion in the stone,and is like in layers.

My guess is a nakayama, it is a sedimentary stone and look a lot like a coticule on the sides except the sedimentary layers are a little thicker than than the coticule and it also has the the rusty veins like your stone. I have a stone that use it in progression with a coticule. As a finisher right after my thurigan . It finishes about 16-18K. I was looking a nakayama stones the other day and most of them are very similar to yours and usually irregular and real rough on one side and are a little more grey than yellow. I am retired and have been collecting stone and straight razors for 10 years. I am just starting to identify the stones and one of the first Things I do is determine the approximate grit of the stone I an trying to identify. while my stone looked and acted like a coticule, it was a lot finer stone than my coticles.

Thank you. I think you are right, it may be a Japanese nakayama. I never had one, nor see one, this one I rub it with a softer coticule, make slurry ,perform a Dilucot, and finish on water only. I get constant HHT from the stone, and is not the case on coticule, just ocasionally I got a HHt before stropping.I am pretty sure , if is not a japanese, is a very hard coticule, even to raise slurry from the stone is very hard, with a DMt 320.
So what kind of Nakayama you think it is? is , for sure a finishing stone, as I bought it from a barber, the seller said, and is very hard.
Thank you for your input.
