Edit: If you are looking for information on how to use a coticule go to coticule.be, Ardennes coticule or search the forums there are lots of people who use this particular type of hone. Some love it other say its a niche hone. I am just learning how to use one myself. There are many videos as well on the net. Hope this helps.
