Factors to Consider When Choosing the Best Electric Knife Sharpeners

There are some things that you must keep in mind as you search for the best knife sharpener for your knife set. This section contains those considerations and will help you make the most suitable choice.

1. Budget

Electric sharpeners range in price as much as they are diverse in models. They could be as affordable as $20 or as expensive as $200. So, you'll want to know what to expect for the amount of money you are planning to invest in your electric knife sharpener.

  • High Budget

The most expensive units will include three stages; sharpening, honing, and refining. The primary reason these models are pricey is because of the diamond abrasives inside them. Diamond is great for sharpening because it is among the hardest materials on the planet. Unfortunately, it also carries a hefty price because of its value which is why these sharpeners range between $130 to $200.

  • Mid Budget

The moderately priced options are the most common models on the market. They cost anything between $50 to $130 and could have abrasive wheels made from diamond but mostly have sapphirite wheels. Sapphirite is also hard and durable but is much cheaper than diamond. These sharpeners will also have two stages which involve combining the honing and polishing processes into one.

  • Low Budget

The low end of knife sharpeners features low-quality models that typically have two sharpening stages. Unfortunately, the angles on these units are fixed, which makes them less flexible than the more expensive ones. Additionally, rather than diamond or sapphirite, they will have ceramic, synthetics, or carbide tungsten wheels. They are quite affordable and will come below $50.

2. Types of Knives

Your kitchen has either Western or Asian-style knives. The Western knives are made according to American or European standards, which involves blades with an 18 to 20-degree angle. They are the most common type of knives in most kitchens and are compatible with both electric and manual sharpeners making them a flexible option.

On the other hand, Asian knives have a Japanese style and feature a sharper angle of about 12 to 15 degrees. Japanese knives are small and slim and are often used for filleting salmons or cutting sushi. These knives are not compatible with typical sharpeners and require a specialized unit. So, if you have an Asian-style knife set, you'll want to ensure that the model you choose can sharpen this style before you spend money on it.

3. Sharpening Angles

Depending on the style and purpose of your knife, it will fall anywhere between 12 to 35 degrees. The angle of the blade informs its strength and durability. The higher the angle, the better the blade. Here's a small guide to help you identify the exact angle of your knives;

  • Butcher knives, chopping knives, and cleavers - 30 - 35 degrees
  • Hunting knives, outdoor utility knives, and pocket knives - 25 -30 degrees
  • Most kitchen knives, chef's knives, carving knives, ceramic knives, and boning knives - 18 -25 degrees
  • Japanese knives, paring knives, and fillet knives - 12 -18 degrees

4. Abrasive Material

Abrasives refer to the grinding wheels inside the electric sharpeners. They can be made from a wide range of materials, but the most common include diamond, sapphirite, carbide tungsten, ceramic, and synthetics.

Diamond is the most durable and hard material, which is why it is used in high-end models. However, you can still find diamond abrasives in some affordable units. It is typically placed in the medium and fine honing slots.

Sapphirite is second to diamond in durability and performance and is a great alternative because it is more budget-friendly. That is why it is popular in most mid-priced electric sharpeners. The quality of the other materials is less than that of diamond and sapphirite. As a result, they are mostly used in low-end electric sharpeners.

5. Sharpening Stages

Some electric knife sharpeners have two stages, while others have three. The first stage has coarse grits that grind some material from the blade, which creates a new and sharper angle. The second stage has fine grits, which fine-tune the new blade angle into a smooth edge. The third stage normally features fine honing or stropping, which is ideal for slim knives.

If you are looking for a replacement for your manual sharpener at home, you can opt for a two-stage unit. This will serve your sharpening needs adequately without having to overspend on a three-stage unit. The three-stage types are better left to chefs since they can identify the more subtle differences in the blade during cutting.

The first stage will eat into your blade, which is why you should only use it for overall maintenance, restoring misshapen blades, and converting knives.
