We are all guilty of overusing knives

It’s easy to forget how effective a properly sharpened knife is. They wow us when we first started using them, but over time, they begin to dull. This is hard to pick up on because of how slow the dulling process is.

Depending on how often you use a knife and what you are using it for, a knife can begin to lose its edge in as little as a few days. If you want your knives to perform at their optimal level throughout their lifespan, it is important to sharpen it on a regular basis. This applies to not only kitchen knives, but also utility and hunting knives. No matter what you are using it for, you will have to sharpen it on a regular basis.

Once a blade begins to dull, you will lose the ability to rely on the edge alone for cutting. Instead, you will have to compensate with added force. This will compromise the cut. It will lead to rips and tears in the material that you are cutting through. The knife can get caught and it can even ruin the project that you are working on because of its deteriorated blade.

A properly sharpened blade, on the other hand, should be able to slice right through many different types of materials. This will make your cutting job much easier and more precise. Once you get used to a dull blade, you may be surprised how much better a sharpened blade can perform.

Fortunately, good knives are built to last. Although the edge will need regular sharpening, the knife itself should be able to last years and even generations. Keeping the edge sharp will allow you to maximize the lifespan of your knife. You can also sharpen an edge to rejuvenate an old and worn down knife and use it like new again.

This is why a great sharpener is important. There are many different types of knife sharpeners that can be used to bring new life into any blade. There are electrical and manual operated sharpeners. There are sharpeners that use diamond to sharpen the blade and others that use stone. There are knife sharpeners that can be used to restore the edge of practically any type of blade.

Expert tip

Sharpen regularly - it may involve only fine-tuning the edge, but otherwise it may require much more work to restore the edge. Sharpen the edge as soon as you notice it’s not working as well as it should.

Above House


The easiest way to identify a dull blade is to find out the age of it. The longer it is used, the more likely it is to require sharpening. If you are unsure, there are several tests that you can use to quickly differentiate a dull blade from a sharp one.

The easiest way to tell is to take a close look at the blade. Hold the blade close to your face and examine the edge carefully. If you see tiny nicks and indentations, that is a clear sign of a worn out blade. The blade should look even and uniform all the way across the edge. If you find any unevenness or deformities, it is a clear sign that your knife is in desperate need of some attention.

If you have a magnifying glass, you can take an even closer look. If you have any knives that are new or unused, you can compare the two edges to get a better sense of what a fresh edge is supposed to look like. The best knife sharpening system will be able to restore your blade to its original form. When you are done sharpening the edge, it should look exactly like a brand-new blade.

Sharpening with Bob Kramer


There are lots of different knife sharpening systems that you can choose from to use for your knives. They range from pull-through and manual sharpeners, to electrically operated sharpeners. Below, we will go over the different types of sharpeners that you may want to consider.


There are several different types of sharpening stone variations. When we say “stone”, we mean any material that is able to sharpen the edge of a blade. Typically, this includes diamond and ceramic stones. You may also be surprised to learn that there are sharpening stones made of oil and water as well.


Diamond is one of the hardest materials known to man. It is extremely durable and it can sharpen any type of material. In this case, a plate will be fixed with small diamond engravings in it. As the edge of the blade is passed through, the diamonds will break away the imperfections and help return it to its original state. There are two types of diamond stones that are used to sharpen blades. These are called mono-crystalline and poly-crystalline. They both work in similar ways and can produce effective results.


Ceramic is very comparable to diamond and that is a material that is extremely strong and is built to last a lifetime. They are relatively maintenance-free as well. Between each use, all you have to do is clean the ceramic with soap and a scrubber so that you remove all of the previous debris that was left on it.

The only downside to a ceramic stone is that it is generally not available in coarse grades. This means you will be limited to fine detailing. In most cases, this will do just fine, so it is usually not much of an issue.

If you are dealing with a heavily damaged knife that will require multiple grade types in order to take it from its dull state to a sharp edge, you may have to use a different type of stone than what ceramic can offer.


It may seem odd at first, but oil can, in fact, be used to sharpen knives. The oil stone, otherwise known as the Arkansas stone, comes in a flat stone surface. It offers a variety of different coarseness grades, making it a very flexible option. The oil stone is one of the most affordable types of stones that you can find. The main drawback of this type of stone is that it has a very slow cut rate. This means it will take longer to sharpen a knife with an oil stone than it will take using a ceramic or diamond stone.


The water stone is similar to the oil stone. The biggest advantage it has is that it is easy to clean and it works a lot more quickly than an oil stone does. The main drawback is that it wears away quickly and will have to be replaced more often than other stone types.


The alternative to stone sharpeners are steel sharpeners. A steel sharpener is a much more common item to see in kitchens and restaurants. If you cook at all, it is very likely that you have already seen or used one of these yourself.

The steel is usually shaped in a long cylinder rod with a handle attached to the end of it. To use it, you simply hold the blade along the long side of the rod and scrape the edge along it at a 30° angle. Do this on both sides several times and it will restore the edge of your blade.

The steel rod will usually be made of steel or ceramic. You can also find variations in diamond as well. In order to find a high-quality steel sharpener, the easiest way to do that is to inspect the handle. A poorly made steel sharpener will feel flimsy and it will break apart more easily. The handle should feel firm and solid when you are using it.

Steel sharpeners will come in different grid types. A finer grit will create a smooth edge, while a more coarse grit will be better suited for restoring heavily damaged edges.


When you are looking for the best knife sharpening system, you will come across several variations. Each of these variations will use some type of sharpening steel or stone in them. If you have a particular sharpening type that you need to use for your knife, make sure you pay attention to this when you are selecting your sharpening system. If you just need one for general purposes, any type of material that we discussed above should do just fine.

Manual vs Electric

There are two main different types of knife sharpeners that you should consider. They are electric knife sharpeners and manual knife sharpeners. Each has their own advantages and disadvantages. We will explain those below.


A manual knife sharpener relies on the user to pull the blade through.

It has a V-shaped set up that you insert the blade into in order to sharpen it. One of the benefits of this is that it sharpens both sides of the blade at the same time. The actual sharpener will typically be made of one of the stone or steel types that we discussed above. It is situated at an angle that is ideal for the edge of the blade.

It only takes a few pools through to take a dull blade and turn it into a sharp one. They are very simple and easy to use. There are also affordable and portable. They are the most convenient type of knife sharpening systems that you will come across.


An electric knife sharpening system is similar to a manual sharpener with the exception that you do not have to do any of the manual work. An electric sharpener will automatically sharpen any blade that you insert into it. You can simply put the blade in the blade slot and let it do its magic.

There are many electric sharpeners that will automatically shut off once the blade has reached the appropriate sharpness level. This is a great convenience, especially if you aren’t a professional cook that knows exactly how sharp a blade should be.

The major downside of this type of sharpener is that it needs to be plugged in and they tend to be bulkier. This makes it more difficult to conveniently store it in a cabinet or pull it out when you need to use it. Instead, most people that have this type of sharpener will usually have to find a permanent place for it on their countertop.


When you are looking for the best knife sharpening system, it’s hard to go wrong with either an electric sharpener or a manual sharpener. Both sharpener types are great options. The electric sharpener will offer more features while the manual sharpener will be more convenient to use and store. Regardless of what your needs are, a sharpener is a must-have in every kitchen.
