Belgian Blue and Coticule sharpening stones are natural-earth stones with unique sharpening abilities.

 

Belgian sharpening stones contain a large percentage of garnet crystals. Garnet is only third in hardness behind diamond and corundum.  The unique shape of the crystals together with their hardness results in a combination of fast cutting and fine honing that is unmatched by other stones. 

 

The Blue Stone is 4000 grit and composed of 20-30% garnet crystals.   It is best suited for sharpening hunting, fishing and kitchen knives.

 

The yellow Coticule Stone is 8000 grit and has a garnet composition of 30-42%.  The Coticule is popular with straight-razor users, woodworkers and knife enthusiasts who want the very best!
