Thread: What is a hybrid coticule?

I'm seeing some stones being referred to as a hybrid coti? What is different about them?

If they are talking about a hybrid, and not a combo, they are generally referring to a Les Latneues coticule. The hybrid layer is between the two surfaces of the Les Latneues. From what I'm reading, it is suppose to be some pretty good stuff, the hybrid layer. I just acquired my first coticule last week. It was advertised as a Les Latneues, but I'm thinking it is a La Dressante with a hybrid layer. Bart at coticule.be is the coticule expert there - knows his stuff.

Thanks. Good stuff on bart's site.

it runs on the electric motor until the bevel is set then switches to the gas motor for the finishing

I imagine it would be a slow cutter?

'Hybrid' Coticules refer to ones that have this weird marbled gray and yellow backing instead of the normal BBW backing. These are typically found in the Les Latneuses layer, though some have emerged from other layers. It is extremely hard (lapping this side is a PITA) and will offer a different honing regime than the yellow part. Don't want to set bevels on it and in general is slow all around, BUT when used as a finisher only it leaves a very smooth edge. In general I find most coticule edges indistinguishable from each other, but razors finished on the hybrid layer I can generally tell take a smoother edge.

Is it strange that after 2000 years or more of use in sharpening this is the first I've ever heard of these kinds of coticules? Or have I just not been paying attention?

BUT WHAT ACTUALLY IS IT?

I can not seem to get a clear answer anywhere. Yes, I appreciate it is grey and yellow marbled and in lieu of BBW, but what is its geological composition?

It is a hybrid of coticule and ????????

I wouldn't worry about it. Being more than 2000 years old, you would naturally have grown weary long ago of keeping up with all these newfangled hones

Actually, the hybrid is not a mix of yellow coticule and BBW. It exists between two layers of yellow coticule and is a yellow/brown marble mixture. I don't know the physical makeup; I'm sure somebody else can chime in on that.

Here are some photos of a hybrid:
