Perfect for finishing sharpening "razor" ...

Tested on a Mora HQ, ceramic face gives almost the original razor sharp.
Tested on a little blunt knife Switzerland (all-purpose knife) diamond face properly rectifies the edge face and ceramics polishes the blade as well as for Mora.
Tested on a kitchen knife a little battered, the stone is too "finishing" for the job, a grinder or a coarser stone is needed to start work.
The case is made of leather and of good quality. (A pressure button to close would have been perfect, but we do not complain)
The stone does well 10 cm, width of 3.2 and 0.65 thick (0.1 and 0.55 diamond face for ceramic face)
Big enough for the job and small enough to be carried everywhere.
