Coticule love... show off your rock

This came from Ryan?

On Ryans blog describing the find..

The photo directly under the header. there are two rows of six stones, flanked by some singles. This stone is in the top row, furthest to the right... before the blushing single..

Pennsylvania Basement Coticule Cache

We can imagine what it would be like to find an untouched stock of antique razor hones. This dream became a reality for one lucky person. A Delaware reseller named George found a bunch of old sharp…

I've never had to do this before..

I'd like to seal what's left of the label to the BBW. What is the clearest and most protective material. I have polyurethane spar varnish here.. I've used it on my JNats.

Wooooaaah... hold on a sec there B! I will categorically disown you as an internet friend if you seal that label over the top of a lovely bit of naturally bonded BBW .

One of the world's great sharpening stones...

Belgian Blue Whetstone

I posted a little while ago about coticules, but I think BBW deserves its own PSA thread. Because if anything... it’s even better. Belgian Blue Whetstone might as well have been custom made for Japanese kitchen knives. It rolls around the mid 1000s, but works quicker than other comparable...

Steam it off and keep in a baggie.

I've got more BBW here than I know what to do with, Oli..

Oh alright then, if you're quite sure... clear acrylic spray lacquer is what you want for sealing a label. Something like this:

So, the stone from the Pennsylvania Coticule Cache has arrived. Very similar to Gary's two coticules. Prominent manganese lines portends a fast stone, and initial tests confirm. I get steel coloring the water within five strokes on plain water only.
A pretty stone..

Here is one of the ones I got from the hoard.didn’t buy it from Ryan, got from the guy on the bay.

Nice looking stone, Bill.

Thank you, David..

I run a knife across my wine colored one last night it's amazing at how much faster and finer it is than the yellow side(leaves micro serrations too). It's my only one like that and every time I use it I think of you ranting about them being of highest quality natural stones and the best polisher out of Europe! (Wildly exaggerated by me of course). Every time I get a good little chuckle. I've got one on the way that I have a feeling will have a similar quality bbw. Good ones are insanely good, kinda like coticule.

Well I have some work to do. The pic on the box is after a good scrubbing and cleaning with soap & water along with simple green and a toothbrush. I don’t think it is oil either. I think it is 100 + years of swarf. There is a layer stuck on the side and some in the box. No smell at all though. Size look and feel says old rock.

I've thought I was breaking off stone while scrubbing 150+ yo swarf off with a steel brush. That looks like a REALLY good one. I've noticed that I lean on my coticules/ bbws a lot more with the new tools/ blades I buy because those hard *** garnets are about the only thing I got that cuts these new mutant steels with blowing my shoulder for a week. If it isn't diamonds, garnets will cut it. Diamond plate slurry helps too. Those diamonds chew up the garnets and make them more aggressive.

Yeah I had to get out an aggressive low grit sanding sponge to get through that stuff. It just gums up a diamond plate and the plate gets the black stuff stuck to it. I don’t know what that stuff was. I chipped it out of the box with a screwdriver. I am wondering if it wasn’t the original label that absorbed all that swarf and deteriorated into a thick almost hard paste. I have had similar on the side of labeled stones and the side part was just like this.
I would not use DN slurry from a Coticule on a razor though. As you say makes them more aggressive as in not a smooth Coti edge.
Well I got the gunk off with a lot of hard scrubbing and effort. Shows a nice pink blush under there and looks very promising. Now to lap flat. It is a hard one though.

A dull(ish) chisel works well too for non porous stones. Amazing stone. Each time I use one I gain a new appreciation for *old* coticules.

Haha... quite right! A decent coticule is an excellent stone indeed, but good Belgian Blue rises to true greatness.

Good looking stone @rideon66. Nice thick BBW layer uncontaminated by any annoying labels .

I may have missed it in the thread somewhere, but how are we aquiring stones from the hoard? I did not see a link to sales anywhere.

From what I know they have all be sold.

Initially the hoard sold on eBay by the guy who discovered it. Some of the stones were resold on FB shaving groups.

After hours of pointless suffering I had to give in and go outside and use Sic powder on this beast. Still took about an hour and 45 minutes to get flat. It eat the W/D and wasn't really budging on the Atoma much. The dip I had to get out was in the blushing layer though so it blushes more now. Love these old ones like this.

Tom, that's really nice.

Very nice, congrats

When you have to break out the SIC on a yellow coti goods things generally follow. That's a beauty, Tom. Congrats.
