Vesihiomakivet, also known as water stones or whetstones, are a type of sharpening stone that uses water as a lubricant. They are primarily used for sharpening knives, chisels, and other cutting tools. Unlike oil stones, which require oil as a lubricant, water stones are designed to be soaked in water before use. This process softens the stone and creates a slurry on the surface, which aids in the removal of metal particles and helps to achieve a finer edge.

Water stones are typically made from a combination of abrasive grit and a binder. The grit size, measured in grits per inch or millimeters, determines the coarseness of the stone. Finer grits are used for polishing and achieving a very sharp edge, while coarser grits are used for repairing damaged edges or for initial shaping. Common materials for water stones include aluminum oxide, silicon carbide, and ceramic.

The process of sharpening with a water stone involves moving the edge of the tool back and forth across the wetted surface of the stone at a consistent angle. The slurry created by the stone and water acts as a very fine abrasive, gradually removing metal from the edge and forming a new, sharp bevel. After sharpening, the tool should be rinsed clean and dried, and the water stone should also be cleaned and allowed to dry completely before storage. Proper maintenance ensures the longevity and effectiveness of the water stone.
