Thread: Combo Coticule, or coticule on slate?

I was looking at getting a coticule, and was looking at a vintage one. I wanted another pair of eyes to look at it. not sure if its coticule on slate or if its a combo stone, i don't see a glue line so I'm thinking combo

Coticule side seems a little thin compared to some of the modern ones Ive looked at. but grain texture looks nice and creamy.

I saw that one too. Looks nice. Imo it's a combo. Looks like a nice one. Hopefully you get it for a nice price.

A nice Stone, really looks like a natural Combo as there are no Signs of glue by looking at the border of the two layers, ver nice!

Looks like a combo.

It has a good layer of Coti on it. I saw quite a few come out of the quarry with about that much Coti on it. Once it's lapped, your good to go, really. Just use a slurry stone when honing.

Hopefully, i know the bidding went up 40 dollars the first 2 bids, so we'll see how committed the other are, i wont spend more then what i can get a a couple moderns on slate though, i know you can get bluestone pretty cheap in that size, and a smaller coti would be ok.

Fendrihan has combo coticules as well as cotis on slate, just as a plan B

Nice looking stone. Is that a 4" x 2" x 1/2"?

I have a 4" x 2" x 1" Surgical Black Arkansas that is one of my most favorite stones, but I have to use short strokes on a stone that size. It's amazing just how much more user friendly a 6" x 2" or 8" x 2" stone is. Though I understand that large Coticules are expensive.

Attaching slate schist to coticules is a new thing, before all was attached to Belgian blue stone as it was valued as much as slate schist is now. No glue line on a vintage coticule means it's a natural combination.
