If you regularly use knives in the kitchen, there will come a day when they become dull. Unfortunately, this outcome is inevitable. While the knife may retain its signature sheen, its cutting capabilities will diminish with consistent utilization. Cutting a tomato may have initially been similar to taking the knife through warm butter, but it will become more cumbersome after the knife has been used many times.

Fortunately, investing in an electric knife sharpener is any easy method to combat this outcome. Making the decision about such a purchase can, however, seem overwhelming when faced with the immense range of different electric knife sharpening options available on the market today. Before making any purchase decisions or doing any in-depth comparative analysis of different models, it is important to first educate oneself about some basic electric knife sharpener characteristics.


Sharpening stages and sharpening angles are two of the most important facets of electric knife sharpeners that one should understand for the purposes of evaluating different models. The proper method of sharpening a knife necessarily involves usually different stages that progressively take the knife from initial sharpening to finer honing, using coarse and fine grits, respectively. Sharpening a knife in this manner is very effective. More importantly, the use of sequential stages limits the quantity of metal that is unnecessarily shed from the blade of the knife, thus maintaining the lifespan of the knife. Electric knife sharpeners with only one stage are available on the market and are often much cheaper. Nevertheless, one should understand that sharpeners of this type tend to shorten the effective lifespan of one’s knife by removing excess metal with each sharpening due to the coarse grit employed.

Another fundamental factor to consider is the sharpening angle. Knives manufactured in different parts of the world and designed for different cuisine types typically have different angles on the actual cutting edge of the blade. This necessitates the employment of different sharpening angles. For example, knifes manufactured in Japan are typically best sharpened using a 15 degree sharpening angle. On the other hand, knifes manufactured in Europe should be sharpened with a 20 degree sharpening angle. Well-designed electric knife sharpeners generally include an option to adjust the sharpening angle to better suit that knife that one is seeking to sharpen. Lower-tier models generally exclude this option in favor of a one sizes fits all approach.

Ultimately, making a purchase decision comes down to your specific requirements. If you have spent a lot of money on a high-end knife set, it will likely be more logical to invest in a more capable electric knife sharpener that can easily accommodate different knife types and sharpen the blades effectively without sloughing off too much metal material from the blade. On the other hand, a cheaper, less-capable model would make more sense for someone with a more entry-level knife collection.
