Wanted to share a success I had, using a coticule. I have a 5/8 TI "Super Gnome", which I couldn't get sharp, with my Coticule. I've honed, again and again, only to find the edge semi workable for about one shave.
Yesterday I've added about 30 x-strokes on the Belgian Blue side – slurried, of course – of the Coticule. I returned to the Yellow side, after, for a non-slurried finish and that did the trick. The edge isn't perfect yet, but after two shaves, I can state that this was a major leap forward.
I really like the idea of a natural single, as opposing to multiple synthetic stones. It took some time, and I'm still improving, but it's worth it.
Next to my desire to share my (great) success, I hoped this would help someone who, like me, almost gave up on the Coticule.
