Kalthoff Natural Sharpening Stone is a whetstone made from Swedish shale, quarried and sawn in Loos in northern Hälsingland. Well known to make a sharp edge among Swedish craftsmen.
Perfect for sharpening not only your Kalthoff Small Carving Axe or any axe but also knives, scissors or anything else with an edge.
The shale is made from mud packed under huge pressure for billions of years, making a high density and even grit well suited for sharpening.
The grit varies but is approx. 1000g.
The sharpening effect is improved with water on the stone, as it removes swarf and stops it from clogging the sharp grit.
The size is big enough to get a comfortable grip, and small enough to fit in your pocket. It is thin enough to sense the edge through the stone when sharpening.
Can be placed on the table and used as a small bench stone for small things like knives.
The Kalthoff Natural Sharpening Stone is a must for everyone that use edge tools.
Protected by a beautiful vegetable tanned leather case, bordeaux shade.
Learning how to sharpen your own tools gives greater self-confidence and understanding of how to use a tool. In addition, it also safer and more pleasurable.
