FAQs

Why Is Sharpening Your Knife Important

Maybe at some point, you may have asked yourself why is a sharp knife a big deal? Well to tell you frankly, a sharp knife makes all the difference, not just in food preparation, but for your safety as well.

Okay first of, do you know that a sharp knife is much safer compared to a dull knife? A sharp knife offers fewer opportunities for errors as it would just easily glide through food without struggle; unlike dull knives which you have to exert more effort into cutting things and that may cause accidents.

Just a tidbit, a dull knife also breaks the cellular structure of your food which alters its taste. So a sharper knife can make your food taste a little bit better. Keep that in mind next time.

Tips On Sharpening Your Knives

Now when looking for the best knife sharpener, you must first know what you need and what suits your lifestyle. In short, choose a method that is convenient for you. If you don’t have the luxury of time to manually sharpen a knife and you don’t have the skills for it, then stay away from stones and steel rods.

If you’re opting for an electrical knife sharpener, then make sure you learn what type of knives you have because not all models work for all types of knives, especially serrated ones.

You may also depend on the quality of the knife you have to determine how many times you may sharpen it. May it be every week or so if you have cheap knives up to once every few months if you own high-quality knives. It is important to note this because it would be easier to sharpen them before they get too dulled out.

Lastly is don’t ever forget to wash your knives after sharpening. When you sharpen a knife, you are scraping material off of your knife’s edge so it is important to clean the knives after sharpening in order to prevent small bits of metal ending up in your food or even worse, ingesting it.


Buyers Guide

There are a few ways to sharpen a knife. You may have seen many home cooks and chefs often use a honing steel, which is a rod of metal used to “sharpen” a knife. A honing steel doesn’t actually sharpen the knife. It just realigns the cutting edge so that it seems sharper and performs better.

Other than that is we have sharpening stones. This actually grinds off material from your knife’s cutting edge forming a new and much sharper edge. This is manual labor since you have to grind the blade onto the stone but it is ideal if you really want to have your knives sharp.

It would also take skills and precision to sharpen a knife well by using sharpening stones and with that being said, there are some people who want to sharpen their knives easily and effortlessly. Electric knife sharpeners are a cook’s best friend because it’s handy and user friendly as well.

There are a lot of electric knife sharpeners in the market and finding the best one at an affordable price may quite be difficult and you might have to read reviews on reviews about it. Well, lucky for you, we’ve done the searching for you, and below are the top 10 recommended electric knife sharpeners available for you and we’ll let you decide which one would be perfect for you.


Conclusion & Recommendations

If you made it this far then maybe you have already picked the perfect sharpener for you. There may be features mentioned that appeal to you or you see the product itself to be pretty convenient for you. If not then maybe these recommendations would help.

If you want to own an electrical knife sharpener without having to break the bank, then I recommend the Presto Professional and the Chef’s Choice 270 Hybrid. With less than $100, you can have easy and effective knife sharpeners which would last you for a long time. Both of these are perfect for home cooks as it doesn’t require much to operate.

If money isn’t really a problem for you then the Chef’s Choice 15 Trizor XV is very much recommended for you. With its sleek compact design and diamond abrasives, you can really expect this to give you professional results every time and would last you for a very long time.

With all that being said, choosing the right electric knife sharpener for you is still up to you and your preference of course. Just make sure you choose one that suits your knife sharpening needs.
