Electric Knife Sharpener Buying Guide
If it weren’t for this amazing gadget, you’d have to go through a lot more trouble than necessary: diamond rods, whetstones, razor strops, and whatnot.
The electric knife sharpener does the job without any extra gadgets, and it can also do some other convenient tasks such as honing tips, polishing, and deburring jagged edges. Anyway, let’s look at the things you should take into consideration when purchasing an electric knife sharpener:
First and foremost, you might not want to spend a fortune on such a device. The whole point is to make your life much easier without being sore on your wallet – the opposite of what buying diamond rods, whetstones, and razor strops would net you.
The price can be as low as $20 and as high as $200, with many of the knives’ properties being dictated by the price range itself:
$130 – $200: The Top Tier
Sharpeners in this tier usually offer three stages: sharpening, honing, and refining, In most cases, diamonds used as the material for the abrasive wheels, and they offer adjustable sharpening angles when you need that extra precision.
If you plan on sharpening a multitude of tools and different blades, then you should definitely put in the extra cash and go straight for the top tier.
$50 – $130: The Mid Tier
While you might still find diamonds being used for the wheels, they aren’t as common and aren’t used as liberally overall. Instead, most electric knife sharpeners in this tier use sapphirite, an alternative material that ranks second only to diamond in terms of hardness and durability.
But the biggest difference is how they handle the final grinding stages. Basically, the honing and polishing stages merged into a single stage and thus help keep the price a little lower.
Below $50: The Bottom Tier
We wouldn’t recommend this tier of electric knife sharpeners unless you’re really tight on cash and need a quick fix in an emergency.
How the Sharpening Stages Work
In most cases, you’ll only see two sharpening stages at work, namely one that’s meant for shedding loose bits of material from a knife (great for repairs) and a fine-tuning mode that simply refines the blade, making it sharper.
For three-stage sharpeners, the third stage involves fine-honing delicate and slim knives, and is really only meant for professional cooks at the end of the day. Most people will do just fine with a 2-stage sharpener.
Furthermore, the first stage should only be used sparingly, namely for annual maintenance, converting a knife, and salvaging a misshapen blade.
To counter the buzzing and vibrations, you should opt for models with a handle that gives you a firm grip, a sense of control, and reassurance when using the device.
To further prevent the electric knife sharpener from slipping or sliding off the countertop, you should select models with rubber feet or a heavy base to keep the unit in place.
