Buying Guide: Important Factors To Consider Before Buying Electric Knife Sharpener

Here are some factors to look for in your electric knife sharpener before buying it. 

Price:                            

Choosing something which is in your pocket is a difficult task. However, investing in something valuable and long-lasting is an easy thing to do. The price of an electric knife sharpener varies from $20 to $200. All you need to do is choose according to your need, and the price will automatically accommodate you. 

If you are looking for a 3-stage sharpening system, the price range will be $130 to $200. These tri-stage sharpeners have wheels made up of diamond, which defines its price. Most of these sharpeners can sharpen all types of knives. So if you are a professional chef, you must go with such electric knife sharpeners, which will sharpen your knife so finely that it will look like a diamond rod. 

However, if you are looking for a knife sharpener for your household, you can get those whose price ranges from $50-$150. Although there is a huge gap in the price, they are useful according to your needs.

The difference is in the material of wheels; some are made up of Sapphirite, and some of the not so fine diamond. In addition, most of them only have 2-stages: the honing and the polishing, excluding the third stage.

Sharpening Stages:

Electric knives sharpener features two or three sharpening stages, named: coursing, honing, and polishing. Both the staged sharpeners perform very similarly to each other, but this makes them differ in prices. A two-stage sharpener, only having honing and polishing, is adequate for the house kitchen. But, it really depends on your own needs. However, a tri-stage sharpener makes more sense for professional chefs because they want to ee

Abrasive Material:

Electric sharpeners grinding wheels, also known as abrasives, are usually made up of diamond or Sapphirite. Both of them provide bright, shiny, sharp-razor-like knives.

However, wheels made up of diamond are the best ones because of their hardness. They sharpen your dull knife to an ultra-sharp one. In comparison, Sapphirite sharpening wheels are less hard than that of the diamond. It is also pleasing, but less durable than a diamond. 

Single-sided or Double-sided electric knife sharpener:

Again, this factor depends on you. If you have serrated knives, then a single-sided electric knife sharpener is the go-to choice. However, it has this significant disadvantage; this type of sharpener usually scratches the knife, making it’ surface irregular instead of sharpening, leading to an ineffective sharpening procedure. In contrast, the double-sided knife sharpeners have a rotary mechanism, which makes sharpening much more effortless.

Angle Guide:

A knife’s angle is the most important thing to look for while sharpening your knives. A knife angle varies from 12° to 35°, depending on the knife’s use and material. So make sure you have placed the knife correctly, without destroying their angles. Always look for those knife sharpeners who automatically fix your knife to a correct angle, using its advanced technology. 

Safety:

Safety is our topmost priority. Always choose those electric knife sharpeners, which have a non-slip base, providing a firm grip. So that while sharpening, the machine makes no slip from the counter top. Look for those types of electric knife sharpeners who only function when the knife is placed correctly. This protects the user from accidentally injuring their finger.

FAQ

How often is there a need to sharpen a knife?

This one is the most frequently asked questions. The number of times you need to sharpen your knife depends on how often you use it, what kind of material is being used to make it, and its angle and style.

Ideally, it is recommended to sharpen your knife professionally after every 1-2 years. However, it depends on whenever you feel like your knife is getting dull; you can immediately sharpen your knife using an electric knife sharpener at home. Moreover, you can only use the polishing stage to give your knife a neat razor-like look. 

What makes Electric Knife Sharpeners better than Manual Sharpeners?

There is always a doubt whether one should opt for manual ones or electric ones. However, both of these options are better than each other. The choice of you getting which one depends on your own needs. Manual ones are for professional use, and they require specific skills and knowledge about stones, etc., that not every person is aware of.

This factor makes electric knife sharpeners a better choice for an ordinary person. You do not need to have any knowledge to operate and handle it effortlessly. There is no risk involved, such as injuring your handles while sharpening them using electric sharpeners.

Moreover, in an electric sharpener, you do not have to worry about the angles, as it automatically adjusts the angle and sharpening stages. Last but not least, an electric knife sharpener is time-saving, as compared to manual ones. 

How long does it take to sharpen the knives using an electric sharpener?

This depends on several factors, including how dull and long your knife is, what kind of material it is made up of, and the abrasive wheel you have in your electric sharpener. 

Possibly, if you just have to sharpen or polish your regular knife, it will hardly take 20-30 seconds. However, if you are sharpening your knife almost after half to 1 year, it will require approximately 10-15 minutes to sharpen your knife. Long and hard, stainless blades require significantly more time in contrast with short and carbon blades. A diamond-made abrasive wheel works typically faster than a Sapphirite abrasive wheel. 

Final Words

Every kitchen needs a knife to make cutting easier and faster. But when you have a dull and blunt knife, it is hard to function with it. For perfect cutting, you need a sharp knife. Sharpen knives work much better and they don’t slip, making it safe.
