Picked a couple of hones up at the flea market. At a buck a pop I figured I couldn't lose. Anyone have any ideas if they are a boon or a bust?Attachment 164246Attachment 164247Attachment 164248
Here is the second one
Attachment 164249Attachment 164250Attachment 164251
The first one looks like an abused coticule, but can be salvaged, maybe,,,,any hone is a good hone, it can be used for something,,,,,thanks for sharing them.
Yeah I'm lapping them now def looks like a coticule but the otherside is really strange with a purple pinkish slurry
Yeah the backside is toast they broke it off and glued it back on. Only the coticule side is usable Attachment 164256Attachment 164257
All cleaned mostly. By the way does thuringian slurry look grey on your fingers but more whitish on the stone?
Maybe it's a combo? - Belgian Blue & Yellow CotiQuote:

It's a shame I can't salvage the bbw but for a buck can't complain much
Nice Coti!! The other might be also interesting post some further pictures lapped, with slurry, etc...might be a Thuri candidate....
Any sawmarks visible ?
yes that is a coticule but a natural combo bbw + coticule. great stone that I often use. The natural combo are less common there as the combo later on my coticule glued on bbw and today the coticule is stuck on a slate
the blue side is also used for sharpening
What about lapping the coti about some cm 1-1,5cm...is it possible to get it flat ?
not fluent in English with a translator I do not know if it's his job so I apologize if this is not very understanding
all depends on the hollow need ratrapper on some of my stones I have made flat on the width and not the length to keep a maximum of coticule
Yes the first is a Coticule with a BBW back. Lap the back (BBW) flat you may still be able to use it depending on what they glued it with.
Yes, Thüringen slurry can look white on the stone and grey dried. If they were togeather it may well be a Thüringen. They come in colors from grey to charcoal and grey to green.
Lap it and take some photos, wet and dry with and without slurry, face back and sides. A Thüringen will most probably have saw marks on the sides.
What are you lapping with?
Here are pics of the possible thuringian. Most notable is left over adhesive on the ends.Attachment 164269Attachment 164270Attachment 164271Attachment 164272
Attachment 164273Attachment 164274
Def has some saw marks. Lapping with a coarse dmt. Thanks guys for the help I've been on a long hunt for a cheap thuringian cause Eschers are insanely expensive
There is a huge gouge missing in the bbw and the lapping would almost ruin the stone going that deep
Is it just a Adhesive or might this have been a glued paperlabel....
Whats the size ?
Dimensions are 60mm by 126mm or 2 3/8s by 5. Your guess is as good as mine about label or glue but it's on both ends.
Glue on both ends doesnt rule out...label was often glued over the working surface and around both ends but iam not shure...Quote:

The hole in the BBW may not matter as long as it does not snag. It looks as though it was use with the hole. The hole looks filled with slurry.
You may want to clean the stone and work on a cookie sheet with a new fresh piece of wet and dry or a diamond plate and save the slurry. Let it dry, collect the powder and fill the hole with powdered slurry dust and drop in crazy glue (CA) to fill the hole, if you have enough dust.
Or just use it as is, I think it will be fine as the hole is parallel to the honing direction.
The sides and end will have saw marks.
You also may not need to lap out the deep scratches. Pick the side that has the shallowest scratches and lap that side only, to save the stone.
One of your photos looks green and the other dark grey. What color is it? Take your photos in sunlight outside.
Nice find, I have found a few in the wild... they are out there.
The photos with the glue are the ends? I think I see saw mark under the glue.
The Green photo does look like a Thüringen with slurry, what’s the other side look like?
Yeah there are saw marks under the glue. It's blue grey dry and greenish when wet. Sorry we don't have any sun today it's gloomy out. Perhaps Tom.
That's a great idea with the ca and slurry dust. Btw I put that slurry in there attempting to lap the stone. Should I just fill with ca then a layer of slurry/stone dust then lap once it cures?
How deep is the hole?
I would do a mm at a time, a mm of dust and couple drops of CA. Let cure then more Dust, more CA. if you have enough dust to fill.
Make sure the stone and dust are dry.
Over fill a bit and re-lap.
I have saved dust and you can easily generate an ounce or two lapping a stone.
As said it does not have to be perfectly flat, just smooth. Flat is nice but don’t waste stone to get it all flat.
Like your Coticule. The flat does not go all the way to the sides, but that’s Ok. You will waste a lot of stone for not much more Real Estate, in my opinion. Just round or bevel the edges lightly.
I agree was pretty happy with where the yellow is. I'll leave that hollow for the toeside and use x strokes.
As long as it’s smooth.
I think the better find may be the Yellow/Green Thüringen which I think you may have there.
One of my 2 dollar Swap meet finds is a Y/G Thüringen and one of my best finishers.
I have several Coticules and still not a “big” fan. Not tossing in the trash… but love the Eschers and Thüringen’s.
Are you a patient man?
If so, lap the snot out of the Coti and see what you've got. I think it could eventually be usable and you might have a candidate finisher there.
Alright sorry to keep going with this so long but I completely lapped one side of the maybe thuringian. There black spots with what look like maybe pyrite inclusions? They are only near the end though. Here's a pic
Attachment 164313Attachment 164314
Try a razor on it, or do a quick lapping of the other side to see of the spots go through. It is not uncommon for a natural stone to be dramatically different from one side to the other. One inch thickness can represent hundreds of years of sediment, a lot can happen in that time of settling.
It also may not matter, won’t know till you try...
Hone to at least an 8K edge then go to the Thüringen, I often do after a 12K Super Stone.
The Coticule may also be a finisher, but Coticules can be one of the most frustrating stones and can take some time to learn the stone to make it perform. Even when you think you got it down, the stone probably has much more to give.
Some love them, some despise them… perhaps it is why there always seems to be a Coticule for sale in the classifieds.
Yeah you're right I need to stop wondering what it is an find out where the metal meets the stone. I took it for a test tonight, but I will probably need to tweak my routine a bit to see what's up. Thanks again everyone for all the help and opinions; much appreciated!
Alright fellas I keep coming back for more. I'm sorry but y'all are a wealth of information. I lapped the more difficult side of the possible thuringian and found some interesting things;
Attachment 165232 dry with inclusions
Attachment 165233 dry close up inclusions/ strata change?
Attachment 165234 wet inclusions and strata color change
Attachment 165235 overall wet. That round dot is just light not something on the hone.
Any thoughts guys. Based on the adhesive on the ends, the near perfect match in size and coloring; could this be a barbers delight escher or something similar? Thank you again guys for all your time and opinions!
Looks like too many inclusions to be an escher I would say
Mhh...i also do not really tend that this is thuringian...not ruling it completely out...
The guess us just a nice fine kind if schist where a mass of these are around in all variations...another pic of one i own which has some pyrite inclusions and a comparable structure to these points you showed...no strata change on this one...i also thought this might be a thuringian but it is not...

Did u ever have any luck pin pointed that one?
Well I ran my Tonsorial Gem through its paces tonight. My progression was Nani 1k, Norton 4/8, Nani 12k and finally the mystery with slurry diluting to water every 7-10 strokes. I am very happy with the results. I would argue whatever type of stone this is it gets the job done.
I would love to loan out some mystery stones at some point and get more expert opinions.
