Thread: Old rock coticule

I'm kind of surprised that the yellow slice is as thin as it is coming straight out of the box. Maybe there was a hype back in the day?

It's a naturally occurring blue & yellow stone . Possibly it's an exceptional stone or that was all they could salvage from the quarrying.

Mate I apologise for that , by all means delete that comment .. I am still curious to it's rarity and collectors value rather than any monetary kind of value. It's very unlike any coti I have used so far ... Almost a grainy sandpaperish feel .... Very fine though .

Check the “BBW” side, it may have been harvested for the blue rock and may be a special stone.

There is so much of the Old Rock/ coticule history that is unknown, in the end it was a business and much of it was just marketing. We must remember that then as now, the largest percentage of the market for hones was for tool honing, not razors, and do not know who they were marketing to.

As said about “Old Rock”, the Old Rock company was the largest Coticule manufacture, and not all “Old Rock” stones came from the Old Rock mine, they purchased from other mines.

“Old Rock” was a company name, the name of a mine,
the name of a vein and a brand.

If the old price list is any indication, the “Old Rock” labeled stones were second in highest price to the Barber’s Special.

If you want to sell for the highest price, put it on eBay, for a dollar, it will bring out the Coticule lovers and ultimately sell for the highest price, today. In days past Coticules commanded crazy prices, but the market reflects demand. There will always be collectors.

.

It's funny you say that as the "bbw" side I find more like the usual coticule feel in the feedback ...that buttery fast cutting feeling.. while the coticule layer is extremely grainy and fine idk this one is abit of a puzzle to me ..

Thanks Euclid that mention of the bbw now makes alot of sense to me now, I never actually new that there was a select grade of bbw ..though it does make total sense .

I guessed that the coticule layer runs deeper in parts of the slab they quarried ??? Idk but i do know I enjoy finding out more about them .. coticule love eh

I had a few smaller Old Rock Extra Extra pretty much NIB and I think some were man put together and some 100% natural since I can't find any other explanation. I still use one, once in a while, with a rather thin layer on a side. Even so, should last for many years.

Lately cotis are selling big $ again. Not having the box will hurt the value though.

Some BBWs are so dense and fine that will offer a nice shave after honing on them. But they are really rare. This looks like one of the older darker layers. Does it feel hard? As far as I could see, these were quite hard.

The one I have has a BBW side unlike any other I've seen, I haven't tried shaving off of it though, but I really should try it.


Also, I have a La Grise with an Orange in between the Coticule and BBW layer, I wonder how that layer acts.


Gotta love natural combination stones, how they were formed, how close they lie to each other and yet have different characteristics.
I've finally figured out the easiest way to easy max out Coticule edges, I should try the same with my natural combo Coticules' BBW side, but in the past I've generally found the Coticule side to be a better finisher.

The dark one were the special BBW, there is a lot written, search Salm Coticule, La Lorraine, Rouge Du Salm and French stones, for even mores mystery and good pics.
