A sharpening stone is the oldest way to restore a kitchen knife, and it still gives the most control over the edge. Unlike pull-through sharpeners, a stone lets you choose the angle and the pressure. The stones below cover a classic oil stone, diamond plates, a ceramic-style bench stone and a pocket-size option.
We have not used these products ourselves, so treat the descriptions as general. Please confirm grit, size and lubrication needs on the current listing before buying. Some stones use oil, some water, and diamond plates often work dry or with a little water.

Kitchen Knife Whetstone FAQ
Which stone type is easiest for beginners?
A diamond plate or a fine ceramic stone needs little preparation. Water stones feel nice but need soaking and flattening.
How often should I sharpen kitchen knives?
It depends on use. A light touch-up when the edge starts to feel dull is easier than a full repair later.
Can I use these on serrated knives?
Most flat stones are not suited to serrations. A tapered rod or specialist tool is the usual choice.
What angle should I hold?
Many Western kitchen knives work well at a moderate angle, and many Japanese knives prefer a lower one. Check your knife maker’s advice.
