I am guessing that first one is a Nantlle Valley stone. Similar to what you got from Oli. This is the one I was talking about in another of your posts.

The longer blue-green one is a Nantlle Valley Stone. The wider, shorter one is a particularly cool and funky-looking bit of Llyn Idwal type novaculite.
Pure razor kino is what those are. Nantlle Valley stone has been my favorite touch up stone lately. Fine llyn idwal are good for razors but the coarse ones are insanely good for knives and have been more elusive for me. I'll never sell either my Nantlle Valley or anymore llyn Idwals, I really like them.
