A Deep Rock Hone that might be NOS

The number stamped on the stone could be an inventory tracking number that allows the quarry to track each finished stone. Just a guess.

Yeah, I think it's more a random inventory number more than anything else too

The '60' represents how many US dollars you should sell it to me for. ;)

Thanks for all the responses. The inventory numbering certainly makes since. So I now have the stone in hand. It is 5 inches x 2.5 inches and the absolute HEAVIEST coticule I own. This thing feels like a brick in my hand. Super dense and very hard.

I honed a F. Schempler Focus 105 on it last night and I am excited to see how the edge will be. The bevels had more or less a mirror polish by the time I was finished. I'm excited for tomorrow mornings shave. I've included some pics of it after I lapped it.

very niceee

Hope the shave is half as good as that stone looks.

I have had one of those, not bad stones. My final scratch marks were around the 8 k range on water, honing to a dry hone.

Nice stone. I have one with similar coloring. Who knows, they could be from the same slab of rock.

Today’s shave was excellent! Very very smooth and keen. I think the shaves can only get better as I learn the stone. Overall, I’m super happy with the stone and excited to get some other blades on it.

The only coticule I have ever really messed with was pretty much the identical stone to that. I seriously want one of these rocks!
