No rock expert, just tossing my thoughts out there :<0)

I don't think the slurry I was seeing was grease/water emulsion. It looked and felt like real slurry. I now think these are relatively soft Arkies. Probably not razor-worthy, but I will use them on my knives.

I'll do some more honing on them and see what the scratch patterns tell me.

Hindostan stones, nice coticules.

My initial tests (on knives) with the two larger oilstones indicates that these are nice, reasonably fast hones around the 2-4K level. They're very consistent, and I see no evidence of inclusions. I'm glad, as I do have a lot of finishers, but not too many medium- to low-grit natural hones.

I tested one of them on my my W&B FBU and it seemed to do a good job on the razor too. I'm still not sure exactly where these hones would fit on a progression. More tests need to be done with and without slurry. I'm not sure that they are fast enough without slurry to be used to bridge a 1K to 8K jump.
