Thread: What Stone Is This?

In an intersting bit of surprise, I've done some lapping to the rough surface of the stone. Here's what it looks like now after lapping on DMT XXC….





The darker spots are just where the DMT plate was contacting the stone during lapping.

Would still think on a mottled Vermont Slate or a Vosgienne/Vosgian stone also when we dont know where these stones come from ;-)

OK, figured it couldn't hurt to update this just for further verification.

Nice looking stone, try it with, a thin slurry and a few drops of Smith’s Honing Solution, or a couple drops of mineral oil. It will wash off with Dish soap and warm water.

Do bevel or round the edges.

My vote is a charnley forest! That green looks too familiar.
Give her the old "hone and hope" technique and let us know how it goes!
Will it put a finishing edge on a razor or is it more of a bevel setter?

Its not a charnly, if you check the left side this shows a typical slate structure so a Charnley can be ruled out....

Definitely not a Charnley, I've pretty much finished lapping this to flat and it sure looks a lot like slate at this point.

I will get some pics up later, granted I only got to lap it with very coarse grit so far. Any recommendations what grit I should lap it with to finish?

I was looking through this webpage, it sure sounds a lot like the variegated purple slate they sell as it seemed weathered how it came and then with lapping became darker….

This was after just a few minutes of very light pressure and water (I didn't create slurry prior to grinding) polishing the primary grind of a utility knife in my possession.
