Thanked: 458It looks like a coticule. I don't know what else it might be. There are dark coticules that are all coticule that were intended for tools.

Thanked: 2Could this be a synthesized version of a coticule. I seem to recall an old thread on here about just such a mystery stone and a prevailing theory was that at some point a coticule quarry saved its leavings and bound it together somehow into a hone. So pretty much just like today's modern synthetic hones only using coticule slurry as its matrix? I am curious but I find this theory to be very possible. I have one of these stones myself. They are aggressive and make good pre-finishers but IMHO they lack the finesse and subtlety of a real natural belgian hone. .....JM2¢

Thanked: 458What is the cutting power of the stone like? How long before the slurry or the surface dulls? It could just be some kind of fine sedimentary sandstone type hone.

Thanked: 168No recomendation Neil , observation ,and exact description. I rarely use oil , liquid soap and water often .
In the past was a mania , everyone used theyre stones with oil , even coticule or thuringians . And the story with the milk and the Cretan hone - i think it is an urban legend . Cretans are oiled stones witch gives them the specific dark color . They impregnate them with machine oil , somethimes even old fried oil , to give the distingtive black color , and because is cheaper .
80 % of the old hones , wich i buy are heavy oiled , sluryed with oil and covered with so called GOO ......
Even after laping you can smel the diesel engine oil on it / M10D /
There was a time that i think this stone was a coticule of some kind , but not so sure now . It is a Fast stone , but not like a coti , the color is similar but not like a coti and the feedback is between coti and slate . BBW reminiscent . I dont know what is it but works well , and they are diferent in grit like the coticules .

Thanked: 169It's not sandstone. It's also not molded, it was definitely cut from some mother stone. Strange. I need to do testing in order to see what it has going for it

Thanked: 458Definitely. Never seen a stone that looks like it that wasn't coticule, and I haven't exactly seen too many large coarse coticules that were intended for tools. Last one I saw was a huge 8x3x1 inch thick sort of beat up stone sold on ebay, and I hope the person buying it wasn't intending to use it on razors.

Thanked: 169Speaking to ppl who seemingly have nearly identical stones the performance seems to fall in between a coti and a thuri but it is able to pull an edge back from a more degraded state than a thuri and bring it back to a shave ready state. It sounds fun.
