What does whetstone mean?
A whetstone is a hard stone used to sharpen the cutting edges of knives, chisels, axes, and other tools. Its name comes from the older verb whet, meaning “to sharpen,” combined with stone. In ordinary use, a whetstone is paired with water or another lubricating liquid so that the blade can be drawn smoothly across its abrasive surface. The expression can also be used figuratively for something that trains or improves the mind, judgment, or abilities, as when reading is described as a whetstone for thought. Although modern knife sharpeners are common, whetstone remains a familiar and evocative term for the traditional method of putting a fine edge on a blade. The word has a long history in English and carries a practical, craft-oriented tone as well as a subtle suggestion of careful refinement.
