How the Vault works
Coticule.be doesn't sell hones. This is a website in support of the user base of this remarkable whetstone.
The selection for the Vault is not based on picking "better than average" quality. We are in fact trying to map Coticule properties according to the layers they are mined from, and the selection is aimed at diversity in the first place.
When it comes to the final edge that can be reached, all Coticules work within very close range. The differences are certainly not significant enough for to possibly like the edge of one and dislike the edge of another.
