Electric Knife Sharpener for 15- and 20-Degree Knives - Precision Edge

In this review of the Chefs Choice professional electric knife sharpener, the bottom line is straightforward: this compact 3-stage unit is best for home cooks and serious hobbyists who want fast, repeatable edges on both western and Asian-style knives. The biggest reason to buy is its precise angle control combined with 100% diamond abrasives, which deliver a durable, polished edge quickly and with minimal guesswork. The review focuses on real use: sharpening straight-edge and serrated blades in about 2-3 minutes with consistent results.

Key Features

• AngleSelect: Lets the user choose a traditional 20 degree edge or a finer 15 degree edge so knives can be tailored for slicing or precision cutting.
• Diamond abrasives: Uses 100 percent diamond abrasives to sharpen and hone edges faster and with long-lasting cutting performance.
• DIZOR engineered edge: Produces two distinct facets that form an arch-shaped edge for improved durability and a sharper cutting line.
• Precision angle guides: Keeps the blade at the correct angle throughout sharpening so beginners can achieve consistent results without experience.
• Three-stage system: Includes dedicated 15 and 20 degree stages plus a stropping stage that polishes the edge for a refined finish.

Who It's For

The sharpener is aimed at home cooks who own a mix of American, European, and Asian-style knives and want a quick, reliable way to restore edges at either 15 or 20 degrees. It is especially useful for those who prefer an electric, hands-off workflow and value the convenience of guided angles and rapid sharpening.

It is less appropriate for people who need custom bevels outside of 15 or 20 degrees, or for professional knife makers who require grinding or blade profiling. Users seeking a fully manual stropping-only setup may also prefer traditional stones and leather belts instead.
