Also, if you’re in North America, you’ll get a one-year warranty when you buy a Work Sharp Knife and Tool Sharpener. But I’m not sure they have a functioning warranty in other continents. Either way, you can be sure you’re buying a product that is both durable and efficient.

3. WEN Dry Sharpening System

Next on my list to help you find the best knife grinder for beginners in 2025, I have a product from Wen, the BG9910 10-Inch Variable-Torque Water Cooled Wet and Dry Sharpening System. 

Over the years, Wen has established itself as a brand that deals in only top-quality. It is no wonder their product made it onto this list. With the Wen BG9910, you get a 10-inch grit sharpening stone, complete with a variable torque leather-body strapping wheel with a 9-inch diameter.

However, that’s not even the best part. The Wen BG9910 comes with a water cooling reservoir!

In case you’re wondering, this water reservoir ensures that your blades do not overheat while you sharpen them. However, I recommend taking some time to read the user manual and understand how the machine works. This helps stay safe while using the Wen BG9910 and ensures you get high-quality sharpening results. 

Once you figure out how the machine works, you’ll be sharpening like a pro in no time!

I should also mention that despite its water cooling system and other desirable features, the WEN BG9910 remains very affordable. However, there is something you should note. The joint between the sharpening wheel and the reservoir is not the best. While you can still get excellent performance from the machine, that joint looks rather flimsy.

Pros

Cons

Takeaway

The Wen BG9910 is perfect if you want a cost-effective option with which you can still attain high-quality results. Its water cooling system is also perfect for people who sharpen numerous blades over an extended period.

4. DEWALT Bench Grinder

Next on my list of the best grinder for knife making is a product from another well-established brand, Dewalt Bench Grinder (DW756).

If you have any blade sharpening project that has proved challenging, the Dewalt DW756 Bench Grinder will likely perform it conveniently. Moreover, the machine is not only very efficient but also quite durable. Its base and its features are a combination of cast iron, which makes it quite resistant to damage.

The machine has several exhaust ports on its rear, which keeps it from overheating as you use it.

Here, I have another product from Wen, their 4276 2.1-Amp bench grinder. This product has the best grinder for knife making on this list in terms of its minimalist design. However, this is not to say that it is any less efficient. The WEN 4276’s sharpening quality has undoubtedly earned it a place in my compilation.

But that’s not even the best part. This machine has one of the lightest weights on the knife grinder scene! Indeed, it amounts to just 16 pounds in all.  So, transporting your grinder from one place to the other is significantly more convenient. 

Moreover, asides from its portability, the WEN 4276 offers users the freedom to use it in a diverse range of workstations and environments. I should mention that the machine is also relatively simple and stratford to use.

However, the WEN 4276 knife grind’s sharpening area is considerably small, being only 6 inches wide. While this is enough for most blades, if you need to sharper a larger blade, you may need to use another grinder.

On the bright side, the WEN 4276 is one of the most affordable knife grinders on the market today.

Pros

Cons

Takeaway

The WEN 4276 is ideal if you’re going to shuffle your knife grinder between, say, your home and your workshop. Moreover, it is also perfect for people who have financial limitations for their purchase.

This machine is ideal for people with limited experience with knife grinders and wants a machine that’s easy to use. Sadly, the Grizzly G1015 may not give you the best result possible in the knife grinding game. More specifically, using this model to achieve a symmetrical cut may prove to be easier said than done.

However, there are some perks to using the Grizzly G1015. 

For one, it has a powerful one horsepower motor and can reach speeds as high as 1725 RPM, which is fast enough to sharpen just about any blade. Besides, the grinder is also very durable.  It comes with an aluminum roller, ball-bearing construction, and a cast iron body. This enables to stand up to the rigors of use from day to day.

The Best Knife Grinders for Beginners: Buyers Guide

Knowing the top belt grinders for knives is only the first step to acquiring a machine that’s perfect for you. The next part is choosing a model that works for your purposes. On this note, I can help. Here a few factors you should bear in mind when buying any one of the products in my compilation of the best knife grinders for beginners in 2025:

Sander and Belt Size

One of the first things you should look out for when buying a machine for knife making is the sander’s size. Generally, you don’t need a large sander, which will make installation a hassle. Instead, choose a sander that’s easy to install and move around.

If you’re not into full-time knife making, a portable sander may be best for you.

Once you’ve decided on the sander size you want, then check that it comes with a belt that has a corresponding size. In my opinion, a 2-inch sander alongside a 74-inch belt works best for knives. But you may not be working with only knives, so weigh your options well before making a decision. 

Contact point

In case you’re wondering, your knife grinder’s contact point is its plate-like surface. You place your knife there such that the contact point keeps the knife from hanging from the side. 

That said, I always advise people to buy a knife grinder with an adjustable contact point of up to 45 degrees. This way, you can also sharpen your knife with the machine.

However, if your contact point is non-adjustable, there is a way around it. While the contact point is generally irreplaceable, you install another point over the existing one.

Speed

Another crucial factor to look out for before buying a knife making machine is its speed.

Do you want a very fast machine or a moderately slow one? If you make only a few knives daily, you can probably get by with a slower machine. But, if you use your machine for extensive knife-making, I advise buying a faster grinder.

However, knife grinders that work at higher speeds will typically wear out their belts faster. So, I recommend choosing a model that has an adjustable control for its motor speed. This way, you can vary the machine’s speed to match your project.

Dust-proof

Dust is the enemy of any machine, even top-end models. Not only can it cause inefficiencies, but it can also cause the machine to slow down. The same applies to the best knife grinding machines for beginners in 2025.

Therefore, it is best to buy a belt grinder for knives with a dust collector if you can. This way, you can easily vacuum the dust when it accumulates. There are even some models that have dust collector systems equipped with their own vacuums!

Ease-of-use

This is particularly important as a beginner. You want to buy a knife-making grinder that’s simple and straightforward to use. 

Models that allow you to change their belts in seconds are typically the best. This is because you may have to switch out the belt several times while making a belt, so you want to make sure you don’t have to struggle with it and waste your time.

FAQs

Is a sander different from a grinder?

Technically, both machines qualify as sanders as they perform similar functions. But there is one crucial difference — their speed. A sander is not as fast as a grinder. Due to this, sanders may not be as effective on metals, while grinders are specifically designed for metals as they can reach speeds of up to 8000 FPM.

What are the different types of knife grinds?

The grind on a knife refers to the shape of its cross-section.  In other words, the thinning of the blade to show its cutting edge. Your chosen blade grind not only influences how you make it but also how you sharpen it.

Here are some of the common types of blade grinds you should know:

• Hollow grind
• Convex grind
• Flat grind
• High-flat grind
• V-grind
• Chisel grind
• Convex grind
• Compound grind
• Asymmetrical grind

Are there specifically-made belts for knives?

The answer is yes. You typically want to buy an abrasive belt with a hardness rating higher than seven on the Mohs Scale. This is because hardened steel has a hardness rating of 7. So, you’ll need a belt that’s harder than your blade.

Excellent options include aluminum oxide, zirconia alumina, silicon carbide, and most especially ceramic (which has a hardness rating of 10).

Why use a belt grinder to make your own knife?

Finding a typical knife is relatively easy. But finding a knife that fits your hand perfectly and has all the qualities you want is a more challenging task. However, with a knife grinder, you can conveniently make a knife with all the unique qualities you want and love.

Wrap Up

More often than not, the quality of the knife you make is directly related to the type of belt grinder you use. Therefore, you must use a knife making machine that works for your needs. Hopefully, my compilation of the best knife grinder for beginners in 2025 points you in the right direction.
