Electric Knife Sharpeners Buyer’s Guide
A sharp knife makes your job easier, whether you are hunting, using it in the kitchen, or for any other purpose. If you don’t sharpen your knives, you are sure to put in efforts that don’t yield quality results apart from wastage of your time. You could always consider buying a manual knife sharpener, but the efforts it entails is just not worth it. Investing in an electric knife sharpener is your best bet. For novices and first-time buyers, choosing a perfect sharpener could be a challenging task. The numbers of options available in the market are plenty. If you are focused on what you need from the electric knife sharpener, you will prioritize the features you want. For your benefit, we have highlighted important factors to consider while purchasing the best electric knife sharpener.
Safety
Your safety is of utmost importance. Opt for knife sharpeners that give you protection/ guard on the sharpener to prevent any accidents. When grinding the knives, the sharpener handle should offer you a sense of control and a firm grip. Sharpeners that are table-top mounted should have rubber slips/ feet to prevent them from slipping off the table and causing an accident. Some variants offer you an anti-cut hand gloves to prevent accidents.
Material
The grinding wheels of a knife sharpener are known as abrasives. They are made-up of diamond, sapphirite, ceramic, carbide tungsten, or synthetics. Diamond is known for its durability, hardness, and high costs. Hence, it may be available in upmarket sharpeners to sharpen delicate knives. Sapphirite comes next for its quality and is commonly used in most knife sharpeners. Depending upon the coarseness required for sharpening the knife, you may opt for the abrasive.
Compatibility
Electric knife sharpeners are available for different knives: those with straight blades, those with serrated blades, Asian knives, European knives, etc. Remember that serrated knives have a special technique for sharpening them and need special grits. You may want to opt for an electric knife sharpener for the type of knives you want to sharpen.
Sharpening process
A domestic knife sharpener works in two phases. In the first phase, the sharpener grinds and throws bits of dull metal, giving a new sharpness to the metal blade. In the second phase, extra-fine grits further sharpen the knife blade and then polish it. You must consider an electric knife sharpener with multiple slots and stages for a high-quality finish. Multiple slots will remove burrs and offer a finer sharp knife. If you are not careful, the metal may keep reducing, and the knife blade may break if you over do it. For professionals, there are additional phases of grinding, which home chefs should ignore.
Durability & Warranty
You would want a product that lasts you longer and still offers you a quality as when best as when you used it first. Do look at the manufacturer’s warranty terms and conditions before you decide.
