yohannrjm's antique store find - Part 2

I mentioned in my other thread (on the slate hones I found) that there would be a second thread about the other hones I found. Here they are.

I recognise the coticule natural combos, of course, but the others are a mystery to me. I would really appreciate your help in identifying them and in helping me get the best out of them. :)

First, the easy ones. A coticule natural combo and slurry stone. This one is thick, with a thin coticule layer. It measures about 4" x 2" x 1".

Before lapping:

The rest look to be oilstones of some sort, but I can't tell. I've never used hones like these, so any help identifying them will be appreciated.

Continued.......

Not much to see there.

Here is the largest one after lapping. It is about 6.5" x 2" x 1".

Dry:

and wet:

Here's the medium one. It's about 4.8" x 2" x 1".

and finally, the smallest one. It's small about 3" x 2" x 3/4".

and it has some interesting striations on the side. Those are layers of stone - not saw marks.

Let me know if you need any other pics to identify these. I don't know what to look for and take pics of with these. Thanks in advance for any help you can provide.

Nice coticules. For some reason I find coticules with the black lines more desirable than a plain one. I like the look of them.

The oil stones I think are Arkansas stones.... but I could be wrong. I don't know my Arks that well.

More then likely Hindostan with that layering.

I've had several types of Arkies, and the two larger oilstones do not look anything like any of the ones that I've handled. However, I've only used new ones. With age and soaking in oil they could look different. They're certainly not trans or black arkies.

I was thinking maybe they could be Washita hones, but I've never seen one of those in the flesh.

Thanks! That sounds probable. I wonder if this is a usable size.

Usable yes.Satisfying?:shrug:

One more bit of data on the two larger 'oilstones': when I rub them against each other (when wet with water), a thin white slurry is raised pretty easily. I don't know if that's because there may be some diamond fragments left over from the lapping on them, or if they're actually capable of releasing slurry. It's not a lot of slurry (not coticule-like).

The more I handle them, the more I'm convinced that, whatever they are, they are the same stone.

hmmmm oil and water ...reminds me of goo of all kinds of colors depending on the oil and how dirty it is. When forced together you get a foam like substance.

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

I'm now leaning towards identifying the two larger oilstones as Arkansas stones as well. After I smoothed them a bit more, I think they may be be soft Arkies. I tried a couple of knives on them, and they seem to be pretty quick (relative to hard and trans Arkies). Slurry darkens quickly with pressure.

I'm glad! I was looking for some nice knife hones. :)

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.
