  • Sharpens fast
  • Comes with 3 belts
  • Many angles
  • May round tip

If you’re looking for a tool to sharpen all your knives fast, Work Sharp’s knife and tool sharpener is for you. Work Sharp is one of the best brands in the business. Their products are American made, ensuring only the highest quality.

Work Sharp has several models of belt sharpeners. This particular one is super fast to sharpen. It doesn’t matter how dull your blade is, this tool will sharpen it in no time.

The great thing about this tool is its angle guides. There is no one angle fits all when it comes to sharpening knives. Different knives need different angles to be properly sharpened.

With Work Sharp’s knife and tool sharpener, you can choose between 20 and 25-degree angles. Because of this, you can sharpen all types of knives. You can use this sharpener on your hunting knives, serrated knives, tanto blades, and even scissors!

Not only does this come with different angle-guides, but it also comes with 3 belts. These belts give you a coarse, medium, or fine grind. This allows you to polish your knife with this same tool.

The only problem with this tool is that the angle guides aren’t very good for the tip of your knife. If you’re not careful, it will round the tip. Instead of having a sharp point, you’ll get a dull tip, making stabbing difficult.

  • Adjustable speed
  • Adjustable angle
  • Comes with 5 belts
  • Expensive

Another sharpener on Work Sharp’s lineup is the Ken Onion edition. This tool provides the same benefits as the previous one, only a bit better.

The upgrade this tool has is its adjustable speed. This allows you to control the speed at which the belt spins. Faster spinning is better for sharpening, while slower suits polishing more.

The angle guides are also improved. Instead of having two set angles, you can adjust it yourself.

The Ken Onion edition allows you to set your angle guide anywhere from 15 to 30 degrees. This way, it doesn’t matter what angle your knife needs, this tool has it for you.

To make things even better, Work Sharp gives you not 1, not 3, but 5 belts. These range from super coarse to super fine. There’s always going to be the perfect belt for every situation.

Combine this with the adjustable speed and angle guide, you have a very versatile tool.

Of course, all this comes with a price. The Ken Onion is more expensive than most electric belt sharpeners. You’ll have to spend quite a lot more to get this tool.

But when you have it, you’ll find that it is well worth the extra dollars.

  • Affordable
  • Built-in ceramic honer
  • Fast sharpening
  • One-angle guide

The last sharpener on Work Sharp’s lineup is the Combo Knife Sharpener. You can say that this is the “weakest” in the line-up, but it is also the most affordable.

Like its siblings, the combo knife sharpener is also very fast to sharpen your knife. As I always say, these tools can get your dull blades to razor-sharp in no time.

The feature that only the combo knife sharpener has is its built-in ceramic honer. Aside from the grinding belt, there is also a strip of ceramic for honing.

You can use this ceramic honer anytime, or for polishing after sharpening. A few strokes on this honer will remove any burr and imperfections. And you’ll get a smooth and sharp blade with it.

That said, there are several things that this sharpener lacks. It only has one angle guide, and it isn’t adjustable either. Given its angled at 25 degrees, which is the most common for knives.

It also comes with only one belt. It does have a ceramic honer, but some people prefer using finer belts for polishing.

The real selling point of this sharpener is the price. It’s difficult to find such an affordable electric belt sharpener that is as effective as this one.

So if you don’t mind not having the extras, this is a great buy.

  • Adjustable speed
  • Durable and sturdy
  • Professional setup
  • No angle-guide

Another sharpener by Work Shapr is the WSSAK081112. This isn’t included in their belt sharpener line-up because it is different in several ways. It looks different from the rest, and it doesn’t have an angle-guide.

It does have all the things that make a great electric belt sharpener though. The fast sharpening that all these sharpeners need is very much present in the WSSAK081112.

This tool is a very professional tool. If you go to the professionals for sharpening, you’re likely to find them using something like this.

Professionals like using these types because they are super sturdy. You can sharpen knife after knife after knife and not worry about anything. They are super well-built, and you won’t have to worry about them getting destroyed anytime soon.

It wouldn’t be a professional sharpener without adjustable speed either. Depending on how much sharpening the knife needs, you can adjust the belt spin speed.

The main problem with this tool is that it doesn’t have an angle-guide. Remember, this was made for professionals. And the professionals should know how to properly angle their knife even without a guide.

That said, it isn’t all that difficult to learn. If you know how to use a sharpening stone, you know everything you need to use this professional tool.

What is Electric Belt Knife Sharpeners?

Most of us already have an idea of what these machines are. This is a simple tool that makes sharpening so much easier and faster.

To do this, these tools use a belt to do the sharpening. Unlike traditional sharpening, it’s the belt that rubs against the knife, not the other way around. You let the machine work on your knife instead of working your knife on the machine.

In its simplest form, a belt sharpener is just a simple tool with a belt that can spin. And when you put the edge of your knife on the spinning belt, it grinds and sharpens it. These tools also come with special features that make things easier for you.

This gives it several advantages over-sharpening stones. But it also has some disadvantages that you need to know. Before we get into that though, it is important to know what these machines are not.

These machines are not those large belt sanding machines. Belt sanding machines are the bigger versions of these belt sharpeners. They are used for so many things, including the making of knives.

Instead, these belt sharpeners are a lot smaller. They are portable, you don’t have to have a specific place for them. You can easily bring them from one room to the next.

Because they’re a lot smaller, these tools are not used for building knives. Instead, they are used for keeping knives sharp. The belt they have is a lot smaller and thinner, so they won’t do well in forging a blade.

With that out of the way, let’s take a look at the advantages and disadvantages of electric belt knife sharpeners.

Advantages of Using Electric Belt Knife Sharpeners

belt sander

Electric belt knife sharpeners are quite popular nowadays. A lot of people prefer using them over-sharpening stones. This is because of the advantages that they have.

For one, electric belt knife sharpeners get the job done a lot faster. It only takes less than two minutes to bring a dull knife to razor-sharpness. The spinning belt eats metal very fast.

You don’t have to set aside time to sharpen your knives with this. Even when you’re on the go, you only have to run your knife through this belt a few times. It will come out sharp and ready to go right away.

Another great thing about these electric sharpeners is how easy they are to use. If you’re familiar with sharpening stones, you know that proper technique is important. Without this, not only will you not get sharp knives, but you can also damage your knife.

WIth electric belt sharpeners, you don’t have to worry about technique. Since the belt will do the work for you, all you have to do is hold the knife to it.

You don’t even have to worry about angles. A lot of good electric belt sharpeners today have features that control the angle. This way, you’ll never have to worry about getting a wrong angle on your sharpening.

Because they’re small, electric belt sharpeners are super easy to bring along. They’re not exactly portable, but moving them from room to room is super easy. Compare this to belt sander machines that are almost stationary due to their size.

Finally, there are several belts you can choose from. These belts have different grit levels. And it is super easy to change between belts.

This allows you to choose the grit at which you sharpen. You can go for a very gritty belt that will sharpen very fast or a smoother belt that will polish your knife.

Disadvantages of Electric Belt Knife Sharpeners

Despite all these advantages, I still prefer using a sharpening stone. The reason for this is because of the disadvantages of these electric belt knife sharpeners. A lot of people say that the advantages outweigh the disadvantages, so it’s up to you to decide for yourself.

The main reason why I avoid using electric belt sharpeners is that they can destroy blades. Yes, you don’t have to worry about technique, but the belt eats metal fast.

Belt sharpeners remove a lot more metal than is necessary. The belt spins so fast, and it cuts away so much metal when your knife comes into contact. That is why it can sharpen super fast.

This will decrease the life of your knife. You’ll find chips and cracks on your blade a lot sooner than if you use a sharpening stone.

If you’re careful, nothing should go wrong. But using these electric belt sharpeners will shorten the lifespan of your knives. That’s why I avoid using them.

Aside from that, they also require more maintenance. You only have to wash and wipe a sharpening stone after using it. These machines require more maintenance such as cleaning, oiling, and others.

They are more expensive upfront than sharpening stones. They also require electricity to function. That’s why you’ll spend more with an electric knife sharpener.

It’s good to know these disadvantages so that you know what you’re getting into. They aren’t all that big, which is why a lot of people prefer using these instead of sharpening stones. For them, the advantages are worth more.


Having an electric belt knife sharpener is a great thing. Whenever you need a quick sharpen, you can get it done in one, two three! The hassle of sharpening is gone forever with these tools.
