Last Updated on November 19, 2022

To get the most out of your knives when slicing, dicing, and chopping, you need to keep them sharp. Great cooking cannot be accomplished with an uneven surface or blunt edges. So, it’s important to know How to sharpen a knife with an electric sharpener.

Sharpening expensive kitchen utensils can be done at home, but it’s more convenient and quicker to have them done at a sharpening shop or a specialty cookware store. In this case, electric knife sharpeners can be of great assistance.

However, using these sharpeners isn’t as simple as it seems. It’s a skill that requires practice to master.

Simplest Way to Sharpen a Knife with an Electric Sharpener

How to Sharpen Knives with an Electric Sharpener

Before you begin, be sure to thoroughly review the user manual that came with your knife grinder. Standard knife sharpeners have two stages and designated slots.

Grit setting/slotting begins with coarse grit. Harder abrasives, such as diamond abrasives, are used in this sharpening slot to remove old steel bits and leave a clean, sharp edge. Second, a finer abrasive is used to hone and polish your knife, resulting in a razor-sharp edge.

Alternatively, some models require only three steps and unique models that can complete the entire process with a single button press. Professional knife sharpeners typically use a two-stage system for sharpening steel knives.

So, let’s get started!

First Step: A dull knife can be inserted into the first slot. To get your utensil to make contact with the crushing stone in your gadget, press as hard as you can on the heel of it. Once you’ve reached the tip, pull it gradually and deliberately.

Second Step:┬áIn the second slot, insert your knife blade. Most models come with an integrated angular velocity guide or honing guide, so you won’t have to stress about getting the proper sharpening angle. About 15 degrees is the usual temperature range for this situation.

Third Step: Slowly sharpen the blade by sharpening it twice on each side. Step number two should be repeated on every edge of your knife at the proper angle to achieve the desired results. To ensure a fantastic finish, all you need to do is reshape your blade twice with an electric version.

Fourth Step: Apply the same technique to the smaller stones and repeat the process. The next step is to use a more delicate gritstone. The blade edge must be passed through twice on each side, just as in the coarse abrasives stage. This should only take a few seconds of your time. Voila! You can now have knives with factory edges, which you were hoping for.

Fifth Step: Clean and dry the blade. Wash and dry your knives thoroughly to remove any remaining metal fragments from the blade as soon as you’re done.

Sixth Step: Clean up, if necessary. Removing metal particles from your knives has been made easier by unique magnets or compartments in some sharpeners. However, you may have to do this manually with some electric grinders.
