The best way to sharpen a kitchen knife is on a whetstone: it removes the least metal and gives the sharpest, longest-lasting edge. If you want speed or less skill, a guided system holds the angle for you and an electric sharpener does the work in a minute, at the cost of removing more steel.
Below we compare the main methods and six tools on Amazon US by edge quality, ease and reviews.

How We Chose the Best Way to Sharpen a Kitchen Knife
To build this guide to the best way to sharpen a kitchen knife, we compared whetstones, whetstone kits and sharpening accessories sold on Amazon US by grit range, abrasive type, stone size, soaking needs, bases, flattening tools and angle aids. We then read patterns in verified-buyer reviews for cutting speed, dishing, flatness, stability and ease of use, and noted when ratings are shared across variants or when the evidence is thin.
Wash knives after sharpening to remove metal swarf before they touch food, and keep cutting tools clean, following USDA Food Safety and Inspection Service cleanliness guidance. Our method is explained on the How We Test page; this is a research-based guide, not a lab test.
Whetstone Method, Step by Step
Prep
Soak or splash the stone; set it on a non-slip base.
Angle
Hold about 15–20° per side; mark the bevel to check.
Sharpen
Work the #1000 side until a burr forms along the edge.
Refine
Repeat lightly on #3000–#6000.
Finish
Strip the burr with light strokes or a strop, then wash the knife.
Tips for Sharpening on a Whetstone
- Soak soaking stones until bubbles stop; splash-and-go stones just need water on top.
- Hold a steady angle and count strokes per side.
- Raise a small burr along the whole edge before changing grit.
- Flatten stones every few sessions.
- Rinse and dry the knife, then let stones air-dry.
