Thread: I got more rocks

Small update,

after performed lapping of stone one I have notices small cranny of (what I think is) copper. You might notice this on some of the pictures. I try hone razor over this cranny and I can tell that in some point edge of the razor is hitting something different than stone itself. Funny thing is that this was not present before I start lapping. After I have removed stone surface this cranny come to picture. I guess I still have some stone left to be used of flip stone and execute lapping of other side:-)

My guess would be Slate, ragstone, slate

Well,

after few testing (I am not sure if this is right) I think hone one is something close to Thuringian, just darker. I honed and test one of my razor using hone #1 as finisher and it was very nice. Much better than my C12k and little better then my LI on oil. Now I will test other hones. Beside that there is more rock comings and more testing ahead of me. I guess at the end I will be just naming them UKNW#1, UKNW#2 and mark possibly closes grit and use it:-). Thank you all for your help!

The copper looking inclusions might be pyrite. Pyrite is not uncommon in slates.

robellison01,

well I read about pyrite on wiki and you might be 100%. it looks like it is pyrite. This also means I can go over pyrite with my edge as it might be damaged.

Does stone #2 sparkle? It reminds me of the stone in this thread -- http://straightrazorpalace.com/hones...recognize.html. I've decided that one is just a basic dark slate with a bunch of sparkly mica. Polishes nice, though.

Pyrite inclusions are bad news if left in place. I have one hone with them, they are hard and will damage an edge. I have read (but haven't had a chance to try myself) that you can dig them out, or drill them out, and then use the hone. That would probably be fine if there are just a couple here and there, but if they are wide spread the hone may not be suitable for razors.

pyrite was not visible at first, then show up during lapping. I guess if I hone little bit on side of the hone I could determinated how far it goes and then decide either avoid this side or cut the stone. If its only few mm into stone stone surface I could flip stone and lap othe side or I could lap stone again in order to remove pyrite.

It's certainly worth a try!
