But it’s not about its case at this low price. As one of the best electric kitchen knife sharpeners, it offers reliable blades for the perfect slices of meat or vegetables. 2 grinding stones are represented in its sharpening stages. The first stone has 600-grit suitable for the rougher part of the sharpening process. The second stone has finer 800-grit, suitable for the finishing touches on the blades.

It only takes a few seconds to have the knives sharp as a result. It is also a simple process in which kitchen porters may learn to do themselves.

cheap electric knife sharpener, Narcissus Electric Knife Sharpener

Narcissus Electric Knife Sharpener

This knife sharpener falls in the middle price range. I have to say it’s somewhat competent and gives good value for money for this price point. The Narcissus knife sharpener offers two stages to sharpen your knives: crude and fine. If your knife is chipped, very dull, or badly dinged up, use the crude stage first and then polish it one the fine stage.

If your knife is alright and just needs extra sharpening, skip the crude stage and move onto the fine. This sharpener will put a 15 degrees angle on your knife’s edge. It also has slots for sharpening scissors and slotted screwdrivers, so I can comfortably say that it’s a proper multitool sharpener.

Moreover, this sharpener is rather prudent about safety. There’s a cooling device in place, and there’s also overheating protection. If you’re using it for 5 minutes, the copper motor will turn off, and it will need 10 minutes to turn back on.

  • It also sharpens scissors and slotted screwdrivers

Taking a Closer Look at Knife Sharpening

If you’re a beginner when it comes to sharpening your knives, here are some tips that should help you out:

  • Sharpen your knives because it’s safer that way. It’s not actually true that a somewhat dull knife is safer for you because it’s less likely to cut your finger. In fact, it’s more dangerous. When you have a very sharp knife, you need less force to cut through your food. This lets you more able to control your knife so that it goes exactly where you want it to.
  • On the other hand, a dull knife requires more force to cut through your ingredients. This means that your fingers are more likely to slip, and the sudden burst of speed may also result in an accidental cut.
  • A sharp knife is also better for the taste of your dishes. It’s been found out that a dull knife actually wrecks the food on a cellular level. The lack of sharpness doesn’t just mar the appearance of your food, but it also causes the taste to deteriorate. In addition, a dull knife makes food preparation much slower.
  • Use either a manual “pull-through” sharpener or an electric knife sharpener. That’s because these systems offer excellent results with minimal effort and in a very short amount of time.
  • If you value convenience and time-saving, then you may want to forego sharpening stones and steel rods for now. These take a long time to learn properly, and for newbies, they’re just impractical unless you can devote some time to mastering these things.
  • Make sure the features work for your knives. Some people may also want to sharpen their bread knives, but then some knife sharpeners don’t work on serrated blades, so beware.
  • Sharpen your knives before they get too dull. This minimizes the time and effort it takes to keep the cutting edge sharp. But how long should you wait before you sharpen your knife again?
  • If it’s a cheap knife that you use several times a day, you may need to sharpen the knife every 2 weeks. But a tough high-quality knife that doesn’t lose its edge easily may only need to be sharpened every 3 months or so.
  • Your best bet here is to note the date when you sharpen the knife, and then note the date when you realize that it has become dull. That should give you a proper time frame so that you can sharpen the knife before it becomes dull.
  • Color the edge of the knife with a sharpie before you start. This will tell you which parts of the edge have been sharpened, and which parts haven’t been sharpened yet.
  • Clean the knife after you sharpen it. This may go without saying, but you mustn’t forget this. You really don’t want to have small bits of metal in your dishes!
