Black Shadow French Fine Finishing Razor Hone Sharpening Stones with Slurry Stone

The Black Shadow is a type of slate stone. It originates from a private family-owned property in France that consists of various grades of slate, allowing for the supply of the full "Shadow" range.

Grit:
With a grain size between 8000 and 10,000+, this stone is dense and hard, making it ideal for finishing razors, knives, and other tools such as gouges, wood chisels, carving chisels, plane irons, kitchen knives, kosher butcher knives, and shechita.

The stone's density also makes it suitable as a base for using Nagura stones of different grains.

Directions for Use:
The Black Shadow can be used with slurry made from a piece of the same stone (included). It's best to use the slurry with minimal water—too much water can cause slippage due to the stone's hardness and create a suction effect. A small amount of water is recommended for optimal performance.

Using the stone with water will result in a glossy polish, while using glycerin or oil will create a more even finish. It is possible to switch from oil to water-based use, but be sure to clean the stone thoroughly before doing so.
