Thread: Coticule Help!

Hello everyone, I bought a coticule couple weeks ago. Last weekend I honed one of my straights and everything went good. Yesterday I had honed another razor and let the coticule rest and dry for an hour or so. When I attempted to put the coticule back in the case I saw a crack on side surface. It wasn't there before. Barely noticeable by nail. What shall I do? Shall I glue it, and lap it? or this stone is waste now? I feel terrible right now. BTW anyone can tell me which type of coticule is this?

That looks like a normal fissure. It seems odd that you say it was not there before. Is there any chance you simply did not notice it?

Does your fingernail or a blade catch at all where it is on the coticule honing surface?

You may be right about I didn't notice before. I an mot sure if blade did catch the crack(there was no chip on the edge). I didn't feel anything until I saw the crack. After I saw it, my fingernail caught it but barely.

You should try to glue the crack in any way.
Even if you don't feel the crack while honing on the surface, if the crack will remain open, the water that penetrates in will most probably led to an enlargement of the crack. The crack from the side seems to be too wide for "normal" CA glue that can brige the gap, so I think hot glue will due better in this case.
Heat up the stone to approx. 80°C (slow heating i.e. in a backing oven) and then use a hot glue stick that you bring in contact with the coticule along the crack so that the glue melts and can penetrate into the crack. That seals the crack and prevents from an enlargement.

If you can feel the crack seriously while honing and the blades catches the crack it is more complicated to repair. You may have to enlarge the crack on the surface to a v-shape and then fill it with clue.

There is a very good guidance for repairing cracks in coticules (and also other hones) that you find here: http://www.coticule.be/faq-reader/it...-coticule.html

Thank you hatzicho, I have a CA but I will need to find a stick super glue. I think I can fill the the crack with CA by a syringe and needle?

Yes you can try this, but the problem is, that normal CA has a very low viscosity and cannot bridge the gap between the walls in the crack. You need a certain filler that can do this. Professional CA glue is availabe in higher viscosities that can do this job better. Or as said hot glue.

You can try the following. Fill the crack with the CA glue you have. While the glue is still liquid lap the coti on the side where the crack is with sandpaper. This will move small coticule particles into the crack that fill the space between the walls and will be glued together with the CA. You may need to repeat this process a few times to have a satisfying result.

No it wasn't from a vendor. I bought it from a store.
