10 Best Kitchen Knife Sharpeners 2026 in the United States

The Chef'sChoice 15 Trizor XV EdgeSelect is a well-designed electric knife sharpener that excels in transforming standard 20-degree knife edges into sharper 15-degree profiles, making it a great choice for those seeking to improve their kitchen knife performance. One of its standout features is the three-stage sharpening system, utilizing 100% diamond abrasives, which ensures a thorough sharpening, honing, and polishing process for both straight and serrated blades. The automatic angle guides enhance ease of use, allowing even novice users to achieve consistent results without much hassle, and the quick sharpening time—about a minute for initial sharpening and just 10 seconds for resharpening—is impressive for busy kitchens.

However, this sharpener does have some drawbacks. The electric operation may not appeal to everyone, especially those who prefer manual sharpening methods for more control. The device also weighs around 4.2 pounds, which might make it less portable and slightly cumbersome for storage in smaller kitchens. Additionally, while it performs well for general kitchen knives, it may not be compatible with all specialty blades or certain high-end knives, limiting its versatility for some users.

The Chef'sChoice 15 Trizor XV is an excellent option for home cooks and chefs looking to maintain their knife edges efficiently. It is especially beneficial for those who own a mix of straight and serrated knives and appreciate the convenience of an electric sharpener. Just be mindful of its weight and the type of knives you own to ensure it meets your sharpening needs.
