valentinziI happened to notice a strange shape of a monkey skull on my sharpening stone recently and thought it deserved a photo before it got wiped away again.
The whetstone is from Swedish shale, quarried and sawn in Loos in northern Hälsingland. Well known to make a sharp edge among Swedish craftsmen. It is useful when sharpening everything from your dear axe to knives, scissors or anything 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 around 1000. The sharpening effect is improved with water on the stone, as it removes swarf and stops it from clogging the sharp grit. (from Kalthoff description)
