Belgian Coticule & Belgian Blue - VINTAGE & RARE Collectable Classic Water Razor Hone Sharpening Stones

Offered here are classic, old mined Belgian Coticule water razor hones with Belgian Blue backing stone from the Ardennes region of Belgium.

As with all old coticules, these are composed of the dual side Yellow Coticule and Belgian Blue honing surfaces.
