The ultimate guide to electric knife sharpeners

If all your knives are dull and you don’t want to spend an hour sharpening each of them by hand, you should consider getting an electric knife sharpener. This is a great tool that can solve the problem quickly and will help you sharpen all knives really fast without any effort required from your side. Moreover, you don’t need to worry about injuries because the knife will never slip and cut you. Basically, you get a safe gadget to do a challenging task for you.

However, you should know that not every sharpener on the market is made of good quality materials and if you just go and buy it hoping for the best, you can end up with the wrong model. In order to help you make the right choice, I’ve done my research and found electric knife sharpeners that do the trick and don’t break the budget. The article will quickly discuss the important features of these tools and how you should use them to achieve the best results.

The best materials for an electric knife sharpener

If you want to buy a sharpener that will stay with you for years, you should consider something that includes diamond coating. Diamond is one of the strongest materials in the world and it’s a perfect material for an electric sharpener. The best thing about this material is that even though this material seem to be expensive, only polished diamond are expensive and they’re used for decorative purposes. The type of diamonds used in sharpeners are much cheaper, so they have affordable price tags.

How to clean the metal shards after the sharpening

When you sharpened a knife, you will have small metal pieces falling off of the unit and it can create a mess. The pieces are dangerous and can easily cut though skin. Therefore, you should pick them up the right way. Some models have a special bin for these pieces and you only need to clean out the bin in order to get rid of every piece. Some models also have magnets, which is perfect for metal piece cleaning. All of them will stick to the magnet inside the sharpener, which will significantly lower the risk of injury. This is why you should always check the manufacturer instructions regarding metal shard cleaning.

Do you need a polishing step?

Some models that you can find on the market will have one additional stage, which is a polishing step. This step is necessary because sometimes the knife can get scratched during the sharpening stage because grinding has happened on the blade. If you want the knife to look like new, you will want to sharpener that have a polishing step in their design. It will make the scratches look more bearable. The other thing about this stage is that it helps remove excessive metal shards off of the knife and ensures you aren’t eating one of the smaller metal pieces after cutting meat with a sharpened knife. If you don’t have a sharpener with a polished stage, just make sure to carefully check the knife after the sharpening.

Consider the type of the edge

A quality electric sharpener should have more than one slot in the design in order to let you choose the edge of the knife. This feature is really important because different knife types require different sharpening techniques. Sometimes, you just don’t need a really sharp edge. And with other knife, a razor-sharp edge is required. For example, you don’t want the sharpest knife to be a butter knife because it should slather. On a contrary, you want sharp edges for your cutting edges.

Serrated Blades

Some sharpeners are suitable for certain types of knives and blades. If you often use serrated knives, you should check model specifications and find a sharpener that is capable of doing what you need. You should also check the way a sharpener does the job and make sure it’s suitable for the knife sizes you will sharpen. Some models are suitable for certain knife sizes only, and you can’t sharpen huge knives in a tiny sharpener and vice versa.

The ease of cleaning

Sharpening a knife can get really messy and cleaning sometimes gets longer that the sharpening itself. When you work with a tool, you need to shave off little piece of metal to make the knife sharper. This is why it’s really important to make sure the device is easy to clean. If you’re going to get something that requires challenging cleaning, you can end up losing little metal shards. Just make sure to read the reviews because first-hand experiences are always the best source of information. Never clean the pieces with your bear hand, it’s better to get nice gloves.

Style and design

Most of us don’t think about knife sharpeners until knives become dull, so oftentimes you find models that don’t try to be eye pleasing. Manufacturers usually think about functionality and barely about style. If you need a sharpener with a beautiful design that matches the kitchen design, you will probably have to pay a higher price to get the product. There are some brands that produce black, stainless steel and white finishes, but you will have to have a higher budget for them. If you plan to keep this product on the kitchen counter, consider investing in a fancier model.

The size of the sharpener

If you want to use it on your kitchen counter or just inside the house, you should consider the size of the sharpener. Some of them are much larger than others. If you want yours to fit in a drawer or on the counter, don’t forget to check the measurements when you’re browsing through product specifications. Sometimes the size of the sharpener affects the size of the knives you can sharpen. If you can’t fit your big knives into a small sharpener, it will be quite useless. The confines of the sharpener and the thickness of the blade should match, or your sharpener won’t do anything.
