As a last effort, before repurposing the knives, I decided to try the LINKYO, and, after following the instructions, I don’t think these knives were this sharp when they were new! So far, so great!!
5. Chef’sChoice 250 Diamond Hone Hybrid Sharpener

It takes a little while to get the hang of sharpening, but once mastered is quite easy. I have sharpened a bunch of knives, and they have all turned out great. This company makes a more expensive sharpener, but for the money this one is great.

Why do I need an Electric Knife Sharpener?
From hunting knives to pocket knives to kitchen butcher knives, they will all lose their edge.
One reason is that most of us do not adequately take care of our knives. Unless we are Bobby Flay or a professional chef, we are not cleaning and properly handling cookware.
For instance, one is not supposed to leave knives in a sink. They should be washed with warm water, and soap then put away. Leaving them in the sink is a bad idea. Placing pots and pans on top of the knife can ruin the edge of the knife faster.
The Anatomy of a Knife
The anatomy of a knife consists of many parts, but here is a basic tutorial.
For reference, I will call the spine the top of the blade and call the edge the bottom of the blade.
- Spine- This is the thicker top or back part of the knife. The thickness of this part helps to give the blade more weight and strength.
- Edge- This is the part that cuts. It is thinner and sharper compared to the spine.
- Heel- The last 3rd of the knife-edge, this is closest to the handle. This part is used for cutting and chopping.
- Tip- The tip is the first 3rd of the knife’s edge.
- Point- The point is the end of the edge of the knife for stabbing or piercing
- Handle- The section of the blade where you grip it.
- Handleguard-this is right below the handle and forms an extra notch to prevent the knife from slipping out of your hand, giving a better grip, and giving it additional weight.
- Tang- The flat end of the knife where the handle goes over. You will not be able to see the tang once the handle is on the blade
- Scales- These are the portions of the handle that connect to the tang
- Rivets- They secure the scales into the tang
- Bolster- This is the connection between the blade and the handle that gives extra strength and balance.
- Bevel- the shape of the edge of the blade
- Honing- Maintaining the sharpness of a blade
- Sharpening- Creating a sharper edge by losing bits of metal on the edge of the blade
- Grit- The coarseness of the material used to grind a knife or blade
- The Sharpening Wheel: The sharpening wheel or westones are made of a natural abrasive material to sharpen the blade. Most usually are made of ceramic, silicon, diamond, or some steel compound.
- Number of Stages in the Sharpening Process: The sharpening process will usually have 2 or 3 stages but can all vary depending on the electric knife sharpener you buy. The first stage (the sharpening stage) removes the metal burrs or imperfections from the edge of the blade. The later stages will smooth and polish the edge.
- Angle Guides- These are built into the sharpener that guides the blade on the best sharpening angle.
- Portability: How easy is it to use an electric knife sharpener at home as compared to an RV or outdoors. As long as you have an electrical socket with a reliable power source, all on sharpeners on this list are very versatile.
- Safety Features: We do not mess around when it comes to safety. All products that have been reviewed meet standards up to both the company and customers for safety. Please make you read all the instructions for your electric knife sharpener before using it.
- Cleaning Ease: It is bad enough you already have to clean the dishes, but who wants to clean up and new mess?
- No one that is who!
- The great thing about electric knife sharpeners is that they make a minimal mess, and it does not get metallic particle dust everywhere compared to handheld knife sharpeners. Most of these products on our list are very easy to clean.
- Power Source: All of the products are corded electrical devices. On average, they will use about 100V to 120V volts of electricity.
Why Does Having a Sharp Knife Matter, They All Cut Right?
The answer is the sharpness of a knife ABSOLUTELY matters!
Having a sharp knife has nothing to do with your skill in the kitchen, but rather it is a safety issue.
Yes, getting cut by a sharp knife will make you bleed more compared to a dull knife. However, trying to cut with a dull blade will put you at risk of getting hurt. Due to the knife being blunt, you must apply a lot more force to cut. Using that force could make you cut too far and knick your finger.
Also, duller knives are less able to get a bite of what you are cutting. Say you are cutting a pepper, and the dull knife slips off of the onion or carrot. That slip can cause the knife to hit your finger awkwardly. I know this has happened to me on multiple occasions, but not anymore!
How does a Knife Sharpener Work?
A knife sharpener works by having the blade be sharpened by something harder than it. You can have stationary knife sharpener’s, or hand-held ones were you provide the force.
They are mostly made from granite, stainless steel, or sandstone. You also have many electric ones like the ones of our list that use a spinning wheel made of diamond, silica, sandstone, or other hard material. The machine does most of the work with you applying minimal effort.
Does Sharpening Damage the Knives?
Yes, if you use a poorly designed or cheaply made knife sharpener, it can cause nicked edges.
The best way to avoid damage is to buy a reliable knife sharpener and make sure you follow the directions to sharpen the knives. Sharpening blades incorrectly could cause ruin to the blades if you are too aggressive when pulling them through the sharpener.
What is a Sharpening Angle?
This sharpening angle is the best angle between the blade and the sharpening material to get the best combination of durability and sharpness.
You will find that most blades need to be sharpened between a 10 to 30-degree angle. The smallest degree angles are those less than 10 degrees. Lower degree angles (under 20 degrees) are typically for sharpening softer or smaller blades to get a very razor-sharp edge.
An example would be a razor blade or the blade that goes on a scalpel (a surgical blade). By doing this, one sacrifices durability for a sharper, better cutting edge.
The larger degree angles ( above 20 degrees) can go up to over 50 degrees. The larger degree angles are for larger blades like axes, swords, or meat cleavers that do not cut as well. The trade-off is that these blades are incredibly durable in return for their blunter edges.
You will find that most blades here in the US, Candian, and European blades have a sharpening angle of 20 degrees.
What is the Difference Between a Tough Blade and a Hard Blade?
At first glance, these two words may seem like synonyms, but that could not be farther from the truth. Hardness is a measure of an object’s ability to resist scratching or abrasions. A very hard material would be something like a diamond. Diamonds can only be scratched or cut by intense heat and pressure. Only things like lasers and high powered diamond saws can cut diamond. Hardness is measured using the Rockwell C scale.
Toughness is the measure of an object’s ability to resist being broken or fractured when a force is applied. An example would be again diamond, cast iron, carbon steel, and graphene (this is roughly 200x tougher than steel!) No matter how much you have been going to the gym; you cannot bend a very tough material. There are many different tests to measure the toughness of an object, including the Notch, Impact, and Fracture tests.
Now, can something be both hard and tough? Yes look at diamonds
However, most blades are a balance between hardness and toughness.
Usually, you must give up one for the other. If a knife is very hard, it will not be very tough.
This type of knife will have a sharp edge and cut things more quickly but can break if a strong enough force is applied.
On the other side, a blade that is tough but not hard is a durable duller blade. Think of larger blades like butcher cleavers, axes, and machetes. Since they are not hard, they do not cut as well, but you can apply a lot more force to that blade. For cutting wood and vines, these types of blades are tremendous! When it comes to slicing garlic or finely dicing a pepper, not so much.
It is very, very difficult to create something that is both hard and tough like diamonds. Diamonds get these high marks for toughness and hardness because they are unique.
These stones are the result of millions of years of pressure and heat under the earth’s surface. These forces pack carbon atoms into the tight and crystalline structure that we see in diamonds.
Sharpening and Honing – Are they the same?
Sharpening is creating a sharp edge on a blade or tool by grinding it against an abrasive substance that is harder according to the Mohs scale. The point of sharpening something is to give it a sharp edge.
Honing, on the other hand, is fine-tuning an already sharp blade. You use a softer type of abrasive material to remove the impurities or imperfect edges from the tool. By doing this, you can add additional lifetime use for your knife or blade.
How often should a knife be sharpened?
Again this depends all on the type of tool or blade you have.
I will generalize that most knives should be sharpened about 1-2 times a year if you do hone your blades.
2-3 times a year if you do not hone your blades in between sharpening them. In the multistep process that most of these electric knife sharpeners use, sharpening is usually 1 of the first steps. Honing is one of the later steps.
Honing is commonly done by a steel honing rod that you may see in the kitchens of professional and amateur chefs. Its job is to remove impurities and crooked edges while not taking bites of the blade. Anyone who has a set of knives should invest in a honing rod, plus you look so cool honing knives!
How to tell When a knife Needs to be Sharpened?
Remember, you do not need all of your fingers to live a healthy life. There is nothing that can test the sharpness of a blade than the thickness of a human finger…. I am joking. I am joking! Please do not test your blade by cutting your fingers off.
All joking aside, you can test the dullness of a blade by gently (again, gently) running your fingers along the edge of the blade. You should be able to tell if your knife is sharp or dull immediately.
That way is still a little dangerous, and I would not recommend doing it for knives that may be already sharp. However, there are other ways; here are 3 easy ways to determine if your knife is getting dull.
- Cut it against either a tomato or an onion- If a knife is appropriately sharp, then it should be able to cut through a tomato cleanly. It should not be a jagged cut where the tomato starts to become smashed when cutting. You can do this trick with onion too. What you are looking for with the onion is if the knife slips off of it. A sharp knife should be able to get a nice bite into the onion even through the flaky outer layer.
- The paper test- to do this, all you need is a piece of copy paper or loose-leaf paper. Make sure whoever holding the paper gives it a firm grip, the paper perpendicular to the knife. Use the knife to cut the paper. A sharp knife will cut paper no problem. A dull blade will tear the paper instead of cutting through it.
- The hair test- Guys will probably have an easier time doing this than girls. Take the knife and hold it carefully parallel to your arm hair. Then gently glide the blade above your forearm and see if the hairs are being cut. A genuinely sharp knife should cut the fine hairs on your arm while a dull one will not.
Finding the best electric knife sharpener is about finding an affordable, reliable device that properly sharpens your blades. On our list, I am sure you will find one that can add value to your kitchen and your bank account. Just remember to follow the instructions, and the rest is easy. I hope you have learned a thing or two about blades and how they are sharpened.
