Thread: What have I found???

Fellow enthusiasts,

I recently stumbled on this honing stone amongst some rubble on a friends building site. Turns out it was in old fishing boat that my friend received as payment for doing a building job. He didn't think much of it and threw it into the waste pile. Needless to say he let me have it when I saw it, but that explains the rather poor shape it was in. It was basically being walked on every day.

It's a blue grey natural stone, and although the pictures don't show it too well, you can see some veins in the rock. I lapped it smooth and it feels very very fine. The slurry was grey in colour. Anyone have a clue what it could be?

Cheers,

Bagman.
