6 Reasons to Use an Electric Knife Sharpener
One reason that puts many people off using an electric knife machine is the amount of heat it generates which can damage and ruin knife blades. However, with materials such as diamond abrasives and advanced technology, this is no longer the case. Here’s some other reasons why you should use an electric knife sharpener.
1. Safety First
Using a manual knife sharpener requires a fair bit of skill and if you’ve never used one before, it’s probably best that you don’t attempt it. Doing so carelessly or even if you’re careful can lead to serious injury. An electric knife sharpener reduces this risk because of the way it’s designed to safely hold your blade in. It doesn’t require much skill to use either.
2. Easy to Use
Sharpening your knife electrically is easy and you don’t need to worry about which angle you need to hold the knife at or how much pressure you need to exert.
This is something that needs to be done with manual knife sharpeners or sharpening stones. Additionally, there are so many varieties of manual knife sharpeners that it’s hard to know which one you should choose especially if you’re not familiar with this sort of thing.
With an electric knife sharpener, there is usually a knife guide which provides a precise sharpening angle. This also gives you control over the sharpening process so all you need to do is hold the knife whilst it sharpens.
3. Quick Sharpening Time
Electric knife sharpeners can hone your knife to perfection in a few minutes or seconds if it just needs a quick touch up. If the knife is quite dull, it can take a longer time but it’s still going to be much quicker than manually doing it. This leaves you with more time to spend on cooking.
4. A Variety of Functions
Manual knife sharpener and stones don’t have any fancy functions to get your knife blade into a tip top cutting condition. It requires techniques that most people don’t usually possess. The best electric knife sharpeners can provide sharpening, polishing, steeling, resurfacing and stropping wheels and all you need to do is stick the blade into the slot.
5. Suitable For Different Types of Knives
As there are many varieties of sharpening stones and manual knife sharpeners, there isn’t one that can be used for all types of knives. For example, a sharpener stone isn’t usually used for kitchen knives and serrated knives certainly can’t be used for it either.
Some manual knife sharpeners can probably be used for a few common household types but that’s no good if you use special types of knives too.
Most electric knife sharpeners are suitable for many varieties of knife blades and materials. You can even sharpen scissors or axes with some.
A few will include usage for special knives too but usually you can get a specialty electric knife sharpener for those. It saves you from having a clutter of the manual stuff in your drawer which can be hard to remember which one can be used for what knife.
6. Maintains Quality
If you’ve got high quality and expensive kitchen knives, it’s best to invest in an electric knife sharpener of the same calibre to keep them in tip top condition. Manual sharpening can cause an inaccurate sharpened angle if you’ve guessed it wrong which will leave you with a dodgy edge and it won’t cut easy either. Although the knife may not be damaged, it ruins the quality of the knife.
Buyer’s Guide For Electric Knife Sharpeners
To ensure you choose the right knife sharpening machine for you, we’ve put together this easy to follow guide on all the points you may want to consider.
The typical number of stages an electric knife sharpener has is 2. Each stage will consist of a wheel with the first stage for pre-sharpening and the second to hone and polish the blade. There are a few with 3 stages but that doesn’t mean it’s the best electric knife sharpener. The extra stage could be used to get a incredibly razor sharp edge or it may be another angled guide.
As there are 2 sides to most knives, both sides would need to be sharpened so to make it easier to go from left to right without turning the sharpener or yourself around, look for ones where there are 2 slots in each wheel.
Many can be used to sharpen straight and serrated knives and the majority is suitable for most widely used materials such as stainless steel, carbon and alloy. Some can even sharpen hunting knives and scissors. It’s a good idea to check what type of knives you will need to sharpen and its material to ensure you get a compatible electric knife sharpener.
Not all electric knife sharpeners use 100% diamond abrasives in the wheels but it’s quite an important material. Knives are unlikely to get damaged as heat isn’t generated during the sharpening process due to the hardness of the material and it keeps the edge sharper for longer. If you’ve got an expensive set of knives, it’s worth getting a machine that uses this material in the sharpening wheels.
Precision Angle Guides
Ensures the knife is positioned correctly for accurate sharpening. All electric knife sharpeners should have these guides installed but if you’re getting a cheap basic one, these may not necessarily have it.
Choice of Manual Sharpening
Gives you the option to manually sharpen and hone your knife to get a really sharp finish but will require some effort from you.
There’s usually no manual knife sharpening skills involved if there’s a knife guide. This is probably something for professional cooks who require their knives to be sharpened to a specific point as it allows you more control.
Electric knife machines with 2 wheels tend to be smaller in size but there are some that can be slightly big due to the way the wheels are placed. If space is an issue, you might want to check the measurements.
Because of the motor, wheels and amount of metal material used, electric sharpeners can get quite heavy. Materials such as aluminium-oxide are used for some machines which makes it a bit lighter so this may be something to consider if you plan on moving it around.
Electric knife sharpeners are usually mains operated which many chefs tend to leave plugged in. There are a few battery operated ones on the market but judging by electric knife sharpener reviews from different users, they aren’t as powerful. If you need a battery operated one, it may be a good idea to look for one that uses both mains and battery to make the most of it.
Ease of Cleaning
During the sharpening process, there will be metal residue left behind which can be cleaned up with a magnet but it can be a long process. To make cleaning up easier, look for a sharpener that has a removable tray to collect the scraps or one with a magnet installed.
Designs such as non-slip rubber feet and a rubber grip handle can help to reduce the risk of injury during use. All machines should have the rubber feet built in but many don’t tend to have a rubber grip handle. It’s not hugely important as you won’t need to hold the machine during use but if you want that extra safety for your peace of mind, then this is something to consider.
How long your machine is guaranteed for and what parts. Most electric knife sharpeners typically have a warranty period of 1-3 years and usually covers the sharpening wheels.
