How Often Should You Sharpen Your Knife?

This is a tricky question. The frequency of sharpening a knife depends on how regularly you use it, what style it is and what material it is made of. As people use a knife for different purposes ranging from mincing, dicing, chopping to cutting frozen meat, you should consider all the factors to find the exact time to sharpen your knife.

How To Choose The Best Electric Knife Sharpener

There are some factors as to safety and convenience that you should take into account before making the final decision on buying an electric knife sharpener. Not to mention, budget is also very important. So let see what you should take into consideration to make the wide decision.

Electric sharpeners usually come with two or three stages to handle kitchen and outdoor knives. While two-stage sharpeners provide less precision compared to three-stage ones, they have quite similar performance and come at a more affordable price. If you simply need a sharpener for your home kitchen, a two-stage one is adequate. However, if you are a professional, you should go for three-stage sharpener as it have many slots for many functions including coursing, honing and polishing.

Sharpening Abrasives

Electric sharpeners usually come with diamond abrasives or Sapphirite sharpening wheels, providing users with shiny and razor-sharp blades.

Sapphirite sharpening wheels are also a hard material, but they tend to appear with two-stage sharpeners, which means that the price is more appealing. So if you are on a tight budget, you can consider those with Sapphirite wheels.

Angle Guide

For those who start to sharpen their knives, angle guide is the top priority.

With an electric knife sharpener, you can feel less stressed when looking for the right angle, even if you just do it the first time.

Remember that a more versatile sharpener may cost you more than a simple one, so you should think carefully how many functions you would like your device to have.

Some may think of buying a new set of knives, which is rather costly. Instead, an electric knife sharpener is good enough to restore your knives’ sharpness and durability.
