Top 4 Best Electric Knife Sharpeners 2016 Comparison Table
A Fascinating Past
The roots of the modern electric knife sharpener stretch back thousands of years. Knife sharpening stones likely played a prominent role in many human cultures during ancient times. The importance of keeping blades sharp caused some early peoples to use rocks to help maintain knives and other implements.
How to sharpen a knife using sharpening stones
Whetstones for sharpening knives come in a variety of grades. The very coarse 220 grit stone is good for chip repairing. The 1000-1500 grit stone is good for standard sharpening of dull blades. A finer 4000 grit stone is good for polishing a knife’s edge to a fine sharpness for everyday uses. An extremely fine graded 6000-8000 stone is best for an ultra-fine edge for specialty uses like slicing fish.
To sharpen your knife, first submerge the whetstone in room temperature water until it’s saturated. It should take about 5 to 7 minutes. When you are done soaking the whetstone, allow it to stay wet on the surface and don’t wipe off any muddy build up as this will help grind the blade edge of your knife.
As you slide the edge of your blade repeatedly over the whetstone one side and then the other, focus on keeping it at a 20 degree angle or at 17 degrees for sushi knives until you achieve the sharpness you desire. Move up to a finer grade stone as needed for the desired edge.
Today, “whetstones” and “sharpening stones” still play a prominent role in many fine dining establishments. Chefs strap the blades across the surface of these useful sharpening tools periodically to keep the metal edges honed to a fine edge. Yet the development of electric motors offered additional ways to keep kitchen knives sharp.
After World War II, many Americans flocked to purchase more convenient kitchen appliances. Electric knife sharpeners reportedly played a prominent role in this consumer movement.
Just as numerous households in rural areas replaced “ice boxes” with modern refrigerators and fire-burning hearths with electric stoves during the prosperous post-WWII Era, marketers promoted the sale of automated kitchen tools, too: egg beaters, toasters and knife sharpening equipment attracted many households tired of the privations and frugalities of the Great Depression and the War years.

The Presto 08800 EverSharp Electric Sharpener is the number one seller on several online retailers. What makes this product so great is that by its build, it will guide your knife for you to create the perfect angle to sharpen your knife for professional-grade results.
