Wooden carrying case with a long tapered whetstone inside of the hollowed-out portion. There is a piece of wire wrapped around the top of the case holding a piece of wood close to the case which may help attach the case to something. The whetstone is scored along the top and has been chiseled down to a taper at the bottom.
Sharpening stones, or whetstones, are used to sharpen the edges of steel tools and implements, such as knives, scissors, scythes, razors, chisels, hand scrapers, and plane blades, through grinding and honing.
Such stones come in a wide range of shapes, sizes, and material compositions. They may be flat, for working flat edges, or shaped for more complex edges, such as those associated with some wood carving or woodturning tools. They may be composed of natural quarried material or from man-made material. They come in various grades, which refer to the grit size of the abrasive particles in the stone. (Grit size is given as a number, which indicates the spatial density of the particles; a higher number denotes a higher density and therefore smaller particles, which give a finer finish to the surface of the sharpened object.) Stones intended for use on a workbench are called bench stones, while small, portable ones, whose size makes it hard to draw large blades uniformly over them, especially “in the field,” are called pocket stones.
