After 480.000 million years + one week the coti arrived yesterday.
First of all : As I have nothing to compare with, I know nothing about speed etc.
It measures 150*40*10 effective mm and has a few red and orange stains. The surface is very smooth and almost glass like with weins almost looking like hard wood..Ìt`s got some small white dots looking like tiny bubbles of air caught in the surface. I took a good look at the coti vault and the one looking the most like it is number 21.
It does take quite some time to build up good slurry but again I don`t know if thats normal.
Offcourse I had to try it out right away and the results were as expected..the edge became more dull than it was before

This was (trying to hehe) using dilucut methode. Tried again using the progressive methode and managed to shave with it..not a good shave but better than expected.
It will definitely take time to learn using a coti as it is very different from artificial hones,but thats part of the fun:thumbup:
A few hours later:
Now I`ve honed 3 razors and things are improving. Slurry seems to build up better and the hone is more agressive. And it leaves the edge mirror like:thumbup: It`s got a really sweet sound when honing..just the right swoooshhh or more like a swissssshhhh
Had some worries about the width of the stone but that`s really not a problem - You were right again Bart - and the 150 mm length is enough to get a nice drag at the entire edge of the razor.
So all in all...I`m a happy honing guy!
