10 Best Electric Knife Sharpeners 2026 in the United States

The Chef’sChoice 15 Trizor XV EdgeSelect Professional Electric Knife Sharpener is a solid choice for anyone looking to keep their knives in top condition. One of its standout features is its ability to convert traditional 20-degree knife edges to a sharper 15-degree edge, which is great for achieving high performance in cutting tasks. The sharpener boasts a three-stage EdgeSelect system, utilizing diamond abrasives in the first two stages for sharpening and honing, while the third stage polishes serrated blades, making it versatile for various knife types.

Ease of use is another strong point, with advanced flexible spring guides that help users maintain the correct angle during sharpening. The straightforward on/off switch adds to the convenience, allowing users to operate it without any hassle. Additionally, the sharpening time is relatively quick, taking about a minute for first-time sharpening and just 10 seconds for resharpening, which is efficient for busy kitchens.

There are a few drawbacks to consider. While it's designed for maximum effectiveness, the noise level of 65 to 75 dB might be bothersome in quieter environments. The weight of 4.19 pounds may also make it less portable for those looking to store it away easily or transport it. Furthermore, the sharpener is specifically tailored for converting and sharpening knives, so it may not be the best fit for individuals who require a multi-functional tool that can handle other types of kitchen utensils. The Chef’sChoice 15 Trizor XV is ideal for home cooks and culinary enthusiasts who prioritize knife performance and ease of use, although its noise and weight may be considerations for some users.

The Chef’sChoice 1520 Electric Knife Sharpener offers a versatile sharpening experience with its 3-stage process. It features the ANGLESELECT system, allowing users to choose between a traditional 20-degree edge or a finer 15-degree edge, which is great for precision slicing. One of its standout features is the diamond abrasives, which are extremely durable and capable of sharpening knives faster and more effectively.

Additionally, the DIZOR engineered design creates a longer-lasting, arch-shaped edge, while the patented ULTRASTROP disks provide a polished finish. The precision angle guides make the sharpening process straightforward by eliminating guesswork, which is a significant advantage for those who are not experienced in knife sharpening. The device is compatible with both straight edge and serrated knives, adding to its versatility.

The Chef’sChoice 1520 is relatively heavy at 4.9 pounds and has a footprint of 12 x 3.37 x 6.25 inches, which might make it less portable and more suitable for a permanent spot in the kitchen. Despite this, its ease of use and the quality of sharpening it provides make it a solid choice for home cooks and professionals alike who are looking to maintain their knives' performance.

The Chef'sChoice Professional Electric Knife Sharpener is designed to handle a wide range of knives, including straight edges, serrated, and both single- and double-bevel blades. It offers a 3-stage sharpening process, which includes sharpening, honing, and polishing with diamond-coated abrasive disks. This helps create a very sharp and polished edge, which is especially useful for maintaining high-quality kitchen knives. What sets this model apart is its ability to sharpen knives at two common angles—15 degrees for Asian-style blades and 20 degrees for European/American knives—making it versatile for many users. The built-in angle guides help ensure consistent sharpening, which is great if you want reliable results without much guesswork.

The sharpener is fairly compact at about 12 by 6 inches, but it weighs 5 pounds, so it’s better suited for countertop use rather than frequent portability. Its ease of use is boosted by straightforward guides and automated stages, though it is a bit older and not the lightest option available. The diamond abrasives are high-quality and long-lasting, which means less frequent replacement compared to other materials.

The price and size might be more than casual cooks need, and some newer models offer additional sharpening stages or more portability. For someone wanting a durable, effective, and easy-to-use electric sharpener for various knife types, this model remains a solid choice.
