Features You Need to Focus On

electric knife sharpener
The market today has so many products on offer that making a purchase could be a back-breaking task. Plenty of things can make your life a nightmare and a dull kitchen knife is one of them. A dull knife is useless as it cannot be used on fruits, veggies or meat. Thankfully, with so many advanced kitchen tools you don’t have to throw all your knives when they become dull. An electric-powered sharpener is exactly what you need in this situation. But, before buying one, make sure you know exactly what features to focus on.

  • Stages

    As you have probably noticed, most models have more than one stage. A “stage” helps you get a perfect blade. While some products have 2 stages, others have 3 or more stages. Now, you will wonder which is the difference between them. Why use a model with 3 stages instead of a product with 2 stages? The most popular models are that one with 3 or more stages. They do a great work on dull blades. On the other hand, the sharpeners with only 1 stage can damage the blade pretty bad. In fact, they have some limitations that you need to be aware of. Generally speaking, the sharpeners with 1-stage are made of knives with a small and thin blade, including the pocket and utility knives.

  • Angles

    As mentioned above, there are so many models available on the market, that it is quite difficult to find exactly what you need. However, to do this, you need to be informed and make a difference between different models. Whether or not you are a chef, it is good to know more about selecting the angle for your knife. Nowadays, most quality sharpeners have a 15-degree or 20-degree sharpening angle. You may wonder what is the difference between them. While the 20-degree angle can sharpen Japanese knives, the 20-degree angle is used exclusively for European knives. There are also, some models that allow you to adjust the angle. However, they are more difficult to use and hard to find.

  • Blade slots

    If you are looking for a quality sharpener, make sure you invest in a model with the multi-step system. It is more efficient and it is capable of sharpening knives of different sizes and shapes. A sharpener uses a multi-step sharpening process if it has more than a blade slot. While the first stage is designed to grind the blade, the other stages are made to smoothing the knife’s blade. However, keep in mind that a blade cannot be sharpened properly unless the process is done at a specific angle.

  • Straight or Serrated edges

    The latest models can easily handle both straight and serrated edges. But there are also some low-cost models that cannot deal with serrated edges. That’s why, if you have knives with serrated blades, make sure you opt for a sharpener that can deal with them. In this case, a sharpener with diamond coated wheels or belts should be the best option.

Diamond Sharpener vs. Ceramic Sharpener

Ceramic Sharpener

There are so many types of sharpeners on the market, that finding the best one is almost impossible unless you know what to look for. Generally speaking, choosing the right sharpener depends on your personal needs, as well as on your skill level. If you have been sharpening knives a very long time, you will probably notice the difference between diamond and ceramic sharpeners.

The diamond types are specially designed to deal with all types of blades. Since the diamond is the hardest type of material, it is often used to sharpen different types of blades in order to help you get the edges sharp as razors. This is an important feature to look out for before making a purchase. The model we recommend the most is the Chef’sChoice 15 XV. It is an efficient device often used by professional chefs. However, if you want something more reliable, take a look at the Chef’s Choice 270. It is our second option and by far one of the best sharpeners out there.

When it comes to ceramic sharpeners, things are a bit different. The ceramic models are made to provide a perfectly polished finish. But, keep in mind that they are made to deal only with ceramic materials as compared to the diamond ones which can sharpen all types of blades. However, when using the ceramic sharpeners, you need to pay careful attention to the process as it can cause abrasions. In fact, you have to be very careful with both diamond and ceramic sharpeners as they can do more damage than good if the model is not properly chosen.

Chef's Choice 15 XV Trizor

Buyers looking for an electric-powered knife sharpener should consider the above-mentioned products which are specially designed to meet and exceed any expectations. After a lot of research into the pros and cons of our final models, we can honestly confirm that the Chef’s Choice 15 XV Trizor is by far one of the best electric sharpeners on the market. As compared to other models, such as Presto 08810 and Presto 08800 which are Sappharite abrasive, the first position is occupied by a 100% diamond abrasive model which comes with a 15-degree resulting edge angle. Also, it is the most powerful device. While our first sharpener needs 125 watts to run, the Presto 08810 uses just 42 watts. However, it still is an energy-efficient device that helps you save a lot of money on electricity bills.

Although the 15 XV Trizor provides superior durability and unsurpassed reliability, it has the highest price on our list, which means that if you have a limited budget, this is definitely not for you. The Chef’s Choice 270 is a quality sharpener under $100. It is affordable, efficient and able to sharpen all types of blades.
