Chef’s Choice 120 is your ultimate sharpener for getting even the dullest knife working to perfection within minutes. With a 3-stage sharpening system, it works wonderfully well for all kinds of knives; gourmet knives, butcher knives, hunting or sporting knives, and even serrated knives.

Construction: This electric sharpener has 100% diamond-coated conical disks at stage 1. At stage 2, there are finer grit diamonds for giving a second bevel. Ultrafine abrasive disks at stage 3 create another micro bevel along with micro-flute cutters that provide a razor-sharp edge. Elastomeric angle guides help in holding the knives at a precise angle and elastomeric feet firmly hold the machine while the sharpening process is being carried out.

The working of the sharpener is based on 3-stages. At the first stage, with the help of the Trizor-Plus system, diamond-coated conical disks create the first angled bevel by making microgrooves on both faces of the blade. At the second stage, even finer microgrooves are made on each face of the blade by finer grit diamonds, and the second bevel is created that is a bit bigger than the bevel created at the first stage.

At the third stage, polishing and stropping of the blades is carried out by ultra abrasive disks that results in the creation of a micro bevel that provides an ultra-sharp edge. The stropping process not only polishes but sharpens the edges of the blade to such an extent that it becomes a micro flute to cut through even the hardest materials like butter.

Easy to use and store: The sharpener is very easy to use as it has automatic angle guides to place the blades at a precise angle. There is diamond grinding for sharpness to perfection and elastomer feet for a firm grip. Make sure you remove all the metal dust and clean it properly before you store it as the clean-out tray is small and does not hold much of the shards and filing.

Buying Guide

What is an electric knife sharpener?

An electric knife sharpener is a gadget that is mostly used to sharpen knives and also polishes it to give a great look. Electric sharpeners come with 2 or 3 stages that will give a sleek, beautiful, and shiny touch to a knife.

Why should we keep the knife sharp?

Whether you are a professional or a home cook, you must understand that a dull or rough knife can be cumbersome to use. It takes a lot of effort to cut through things and also a lot of time. A sharp knife, on the other hand, makes your life a whole lot easier when you cut through almost anything with no stress on your wrist. It definitely saves time and energy. Plus, you enjoy the time you spend prepping up for the meals if your tools slide through your ingredients like butter.

How many ways can you sharpen your knives?

There are several ways to sharpen your knives, from traditional to modern and advanced gadgets. For some, honing and sharpening with a whetstone is much better than using an electric sharpener. The following types of sharpeners are available for giving your knives ultra sharp edges.

Sharpening steel: This is a traditional way of sharpening or honing a knife that is not dull. In fact, the knife is already sharp and it attains a bit of extra sharpness to glide through coarse stuff and to carve a whole turkey or chicken.

Sharpening stone: This is also a traditional way but mostly used by professionals. This process of sharpening the knife is most reliable, durable, and results in attaining extremely sharp blades if you actually know how to use the stone for sharpening. A variety of stone sharpeners include oil stones, whetstones, and diamond stones.

Ceramic plate: If you don’t own any of the above things, you can use the rough surface at the back of a ceramic plate to sharpen your knives.

Electric knife sharpeners: Modern way of sharpening knives is with the electric knife sharpeners that can be battery operated or plug into a power source. They usually have 2-stage or 3-stage sharpening processes. They use belts or diamond grinding stones for sharpening, honing, and polishing.

How to use an electric knife sharpener?

Electric knife sharpeners usually have a 2-stage or a 3-stage sharpening process with variation in grinding from coarse to finer side. It is advisable to sharpen the blades with the coarse stone and then with the fine one. Following steps would help you in using an electric sharpener more efficiently:

  1. You should place the heel of the knife in the guiding slot and press the knife downwards to make a connection with the grinding stone. Then, start sharpening from the heel and slowly go towards the tip.
  2. The knife should be at a certain angle, usually 15-degree to 20-degree, when it slides through the slot. This angle is attained automatically by the sharpener when the knife is being ground.
  3. Since electric knife sharpeners work very efficiently, you just need to pass the knife through the coarse stone of the sharpener only twice on each side to get a perfectly sharpened blade.
  4. The same process needs to be repeated for the finer stone to get a polished & honed blade.
  5. Finally, properly dispose off the metal shards, filings, and dust. You can also use a magnet to collect this stuff. Wipe the sharpener with a wet cloth and then dry it with a towel. Rinse the knives to ensure complete removal of the metal dust.

How to know if your knife is sharp?

Once you have sharpened your knives, you need to test if the knife really is sharp and would do the job it is meant to do. The most common way of doing it is to glide your thumb over the blade from the tip to the heel but this would not satisfy you entirely and is also dangerous and unadvisable. Alternatively, you can use the following two ways to test the sharpness of the knife.

Paper cut: For this, take a sheet of printing paper or a fairly hard paper that resembles printing paper and glide the knife from top to bottom. If the cut is smooth, then you have succeeded in sharpening your knife to perfection.

Tomato slicing: Another way of determining if your knife is really sharp is to slice a tomato with its skin. If thin slices come off smoothly, your knife has become ultra-sharp. If not, you need to place it in the electric sharpener once more.

Conclusion

Well, folks, this is all you need to know for keeping your knives sharp as swords so that you carve your turkey perfectly on Thanksgiving. I hope the list of electric sharpeners I have provided helps you make a decision in acquiring the perfect one for yourself!
