Best electric knife sharpener-things to consider

Now there are some factors you should consider before buying the right best over the range microwave convection oven combo Here’s some of them:

1. Price

The first thing to consider before buying an electric knife sharpener is the price of the model you’re buying. They can range from $20 to a whopping $200; therefore, we recommend purchasing the one according to your kitchen knives’ needs. If the sharpener you buy doesn’t support the honing of your specific knife, you’re simply wasting a considerable fraction of money.

2. Safety

Safety should be one of the most important factors to consider before buying an electric knife sharpener. Just like you should get a knife that won’t hurt your hand by cutting it, you should also get a knife sharpener that won’t put your hand at risk of getting scratches.

It would be best to get an electric knife sharpener that has a precisely placed guard feature. No matter how alluring or contemporary the sharpener looks, you shouldn’t get it if it doesn’t support any guard feature.

3. Knife Compatibility

It’s a fact that you have to remember that not all electric knife sharpeners are compatible with every kitchen knife. It can be infuriating to buy a new knife sharpener costing you almost 100 bucks only to find out that it doesn’t support the honing of your specific kitchen knife.

Many models in the market offer compatibility with all the kitchen knives, but they’re much more costly than the others. Therefore, before buying one, make sure that it sharpens your knife, specifically if you have knives with thin blades, serrated blades, curved ones, etc.

4. wheel material

The material of the sharpening wheel tells us how effective the electric knife sharpener will be. They are also known as the grinding wheels or abrasives and they’re available in:

  • Ceramic
  • Diamond
  • Sapphirite
  • Carbide tungsten
  • Synthetics

Diamond is considered the best material for grinding wheels as they sharpen your knives with great precision. No other material can compete with the solidness and durability of diamonds. However, it’s not that suitable for delicate blades as it can damage them, and also, they’re only found in high-end electric knife sharpeners with a hefty price tag.

5. Sharpening Stages

It would be best to choose an electric knife sharpener having a minimum of two sharpening stages. The sharpener offering more steps results in better outcomes as the blades are initially shaped with abrasives, and then they’re smoothened in the other stages.

Apart from giving you a fine finish of the blade, a sharpener with more sharpening stages also extends your knife’s durability. Therefore, select the one with two or more sharpening stages but never the one with only one sharpening stage.

5. slot

For more flexibility, the electric knife sharpener you choose should have more than one slot inside it. More slots in an electric knife sharpener equal the added efficiency and more extraordinary performance as one can be used to remove the burrs and the other to hone and sharpen the blade efficiently.

Frequently Asked Questions - FAQs

It entirely depends on what type of model of the electric knife sharpener you’re buying and also the angle at which you’re holding your knife while honing it. If you purchase a cheap model, it can put scratches to your knife’s blade or can also cause denting. In contrast, a high-end sharpener will sharpen your kitchen knives without any flaws.

In addition, if you aren’t moving the whole blade through the electric sharpener, it would result in uneven grinding. Also, the wrong angle can put dents, can bend, or even cause broken edges to your kitchen knife. Therefore, you need to be extra careful at how you hold the knife while using the sharpener. 

You should sharpen your kitchen knives after every two to four uses at home, as doing so will align the tines of your knife and give it a much sharper feel. In addition, we recommend getting your knife honed professionally after a year or two. This way, the blade won’t get dull, and you also won’t have to spend more money on getting a new knife.
