The Zulu Grey narrow cut hones are ideal for travel use as a touch up hone. They are also very handy for honing smiling blades.
Quarried by hand in small numbers, the Zulu Grey is a unique, indurated sedimentary rock formed over 200 million years ago in the late Permian Period in the province of KwaZulu-Natal, South Africa. The stone is quite hard, exceptionally strong and dense. The Zulu Grey whetstone is quarried for its ability to impart a smooth final shaving edge on Straight Razors, however it would be equally effective at finishing a wide variety of fine-bladed tools and instruments. The stone is of course a natural product and as such each hone has an inherently unique appearance.
