Sharpening stone

Sharpening stones, water stones or whetstones are used to grind and hone the edges of steel tools and implements.

Examples of items that may be sharpened with a sharpening stone include scissors, scythes, knives, razors and tools such as chisels, hand scrapers and plane blades. Though it is sometimes mistaken as a reference to the water often used to lubricate such stones, the word "whetstone" is a compound word formed with the word "whet", which means to sharpen a blade, not the word "wet". The process of using a sharpening stone is called stoning.
