A “wet stone” is usually a mistaken term for “whetstone,” which simply means a stone used for sharpening. Whetstones can be either water stones or oil stones depending on the lubricant they are designed to use.
Water stones use water as a lubricant and are known for fast cutting speed and quick sharpening. They are commonly favored for sharpening Japanese kitchen knives because they produce very refined edges, but they wear faster and require more maintenance and flattening over time.
Oil stones use honing oil to reduce friction and carry away metal particles during sharpening. Common oil stone materials include novaculite, aluminum oxide (India stones), and silicon carbide (Crystolon stones). Oil stones generally cut slower than water stones, but they are more durable, lower maintenance, and often preferred for everyday knife sharpening, tool sharpening, and workshop use.
