Best Electric Knife Sharpener Buying Guide & FAQ
Things To Consider Before Buying An Electric Knife Sharpener
Here are a few things to consider first before pulling out the cash for an electric knife sharpener.
- What kind of knife do you use? Before picking out an electric knife sharpener, you must be certain that it can work on your knife. Not all electric sharpeners can work on serrated knives, for example.
- Space: How much space do you have on your kitchen counter to accommodate an electric sharpener as they are much bigger than manual sharpeners.
- Abrasive material: Be sure to find the right abrasiveness for your knives as electric knife sharpeners use grits to provide some amount of abrasiveness. Diamond abrasives are the most popular choice among buyers.
- Sharpening stages: Electric sharpeners, as you may have noticed from this review, have different sharpening stages to choose from.
- Angles: Angle guides help to position your knife for sharpening properly. The ideal angles are usually from 15 degrees to 30 degrees.
- Versatility: How many knives can the sharpener handle at a go?
- Cleaning: Some of the sharpeners come with debris collectors in-built. This makes cleaning very easy.
- Other factors you can consider include price, portability, warranty, and noise level.
How To Sharpen A Knife With An Electric Sharpener
Electric knife sharpeners are very easy to use.
First, place the blade of your knife in a provided slot, pressing the heel of the knife until you are certain that it has made contact with the grinding stone.
Next, make sure that the knife is slid through the provided slot and pass the blade of the knife slowly through it two times on both sides of the blade.
Once done, repeat the process, but this time on the finer stones.
When you finish, do not forget to wash the knife and let it dry.
Pros And Cons Of Using An Automatic Knife Sharpener
An automatic knife sharpener is a very fast option to the manual ones. For one, it requires less time to sharpen - usually in a few seconds. It also requires very little effort. Because it makes use of gravity, you do not need to apply any effort to get the work done, unlike the manual sharpeners. Plus, there are electric sharpeners that are versatile and can work on serrated knives also.
However, using an automatic or electric knife sharpener comes with some disadvantages. To begin with, if you do not like noise, then the electric sharpener might get on your nerves with the noise it makes. Secondly, it can be a bit too effective that it can actually overdo the sharpening and leave the edge of your knife thinner than it needs to be. Also, they are bulkier as compared to the manual ones and, thus, require much more space.
Best Electric Knife Sharpener FAQ:
Q: Are Electric Knife Sharpeners Bad For Knives?
A: As mentioned earlier, most electric knife sharpeners have the tendency to overdo the sharpening and, therefore, usually chips off more than necessary amounts of metal shards from the blades of your knives. When this happens too often, you will eventually destroy your knife. Thus, it is very important to do enough research about the brand of electric knife sharpener you want. However, it is always best to combine the manual and the electronic just to limit how often you use the electric knife sharpener.
Q: How Often Should A Knife Be Sharpened?
A: Unless your knife feels blunt, you normally do not need to sharpen it. However, when it comes to stainless steel knives, you should hone when you use it every two or four times. Carbon steel knives, on the other hand, should get their honing after each use to keep them sharp and ready for the next use. When you hone your knives regularly, you do need to sharpen them regularly - once or twice a year would be enough.
Q: Can I Sharpen Scissors With An Electric Knife Sharpener?
A: Yes, you can. However, there are specially made electric knife sharpeners that can sharpen scissors also. To be on the safer side, it is best to use one of such electric knife sharpeners as not all of them are designed to sharpen scissors.
