Sharpening stones are indispensable tools for the precise sharpening of knives, tools and other cutting blades. They are made of various materials such as natural stone, ceramic or diamond and offer an effective method of bringing blunt blades back to a sharp state. Sharpening stones are available in different grain sizes, from coarse to fine, so they can be used for both rough processing and fine polishing of the cutting edge. Regular sharpening with a sharpening stone extends the life of blades and optimizes their cutting performance. They are suitable for kitchen knives as well as hunting knives and hand tools.
