Thread: Salmen's hone, London

Forgive the necromancy here but I was wondering if anyone might be able to shed any light on a stone I have that I believe is the same as this. I know Salmen sourced stones from various quarries in Wales, and the rest of the UK, and elsewhere in the world. So I don’t know if there’s any way of telling exactly what it might be...?

Mine is 8x2x1/2”, and judging by the box can never have been much thicker. It’s quite fine, finishes a razor really quite well feeling almost Thuri-like in use, and notably very soft kicking up a lot of dark grey, almost black slurry as soon as an atoma hits it. Relatively dark blue-grey with some quite pretty kinda mottled 3d surface patterns when wet.
