Which Types of Knife Grinders to Use for Metal Work?

a) Different Belt Size:

The belt grinder type depends on the belt size. Let’s learn more about different types of belt grinders from below:

1” X 30” Belt Grinder: This type of belt grinder comes with the cheapest price tag. They are versatile enough and deliver the same result as the expensive machines. A beginner can easily handle and use them too. They are suitable for light-duty and DIY projects.

A few drawbacks of the 1” X 30” belt grinder are, that the motor is less powerful, and as a result, it is quite challenging to get a rough surface. Also, the frequent changing of the belt is necessary.

1” X 42” Belt Grinder: The performance of 1” X 30” and 1” X 42” belt grinder is similar. But there is a small selection of readily available abrasives for it; it is not recommended. Shelling is not entirely worth it for a 1” X 42’ due to the similar price of a 2” X 42” and the provision of a wider belt for more durability.

2” X 42” Belt Grinder: This is one of the most popular types of belt grinders, and most manufacturers make 2“ X 42” belt grinders. They are equipped with a 6” disc sander on the side and deliver the best result in a knife-making project. These tools are easy to use and the most efficient belt grinder compared to other types.

They also have drawbacks. These belt grinders are prone to bog down. They are limiting the grinding capability.

4” X 36” Belt Grinder: It is another most common and widely used belt grinder. You will find them in different hardware stores. They are built for a woodworking project and can’t offer the best result in a knife-making project.

Because of the wider belt, bog down is a common problem of these types of belt grinders.

b) Bench Grinder:

use Bench Grinder

Powerful grinding wheels make a bench grinder eligible for multiple tasks. All bench grinder models don’t come with similar-sized grinding wheels. 6” – 10” is the grinding wheel size. Also, they are equipped with different grit to allow you to do a wide range of functions.

Bench grinders are suitable for grinding, sharpening metal objects, cutting, removing rust, etc.

c) Disc Sander

Disc Sander use

A disc sander consists of detachable sandpaper. The sandpaper comes with a circular shape, and it is attached to a wheel that rotates with the help of compressed air or an electric motor.

Based on the sanding grit, you can use it for many tasks like smoothing a rough surface and many more.

Things to Consider Before Buying:

As stated earlier, belt sanders are efficient in making knives. But you can’t pick any belt sanders from the market. If you buy a belt sander without knowing the essential considerations, you will lead yourself to a cheap quality machine.

This is why we made this buying guide, where we will discuss the essential factors that you will need to keep in mind.

a) Ease of Use:

Let me ask you a question, will you operate a power tool that is not user-friendly? I believe the answer is NO. It is essential to buy a knife grinder that is easy to use. However, every power tool has a learning curve. And your picked knife grinder has to come with easy-to-use characteristics after you get familiar with it. For instance, you should replace the belt within the shortest possible time.

Many knife grinder models are available that are available with easy-to-replace belt features. These models allow its user to change the belt within a few seconds.

You may think that it is not an essential factor. But this feature will come in handy when you need to change the belt when making a knife.

b) Motor Horsepower [minimum 1/3 HP]

Through the motor horsepower feature, you will learn about the power of a knife grinder. Generally, small knife grinders consist of a 1/3 HP motor. You can’t question these knife grinders in terms of performance, but you shouldn’t buy these knife grinders if you make knives for a living.

In contrast, more giant knife grinders are equipped with a 1 HP motor. Since they are more potent than small knife grinders, you can easily make knives with them. But they are expensive. In comparison, small knife grinders are available with an adjustable speed settings feature. Also, being a small tool they are easy to handle. Moreover, they come with a wallet-friendly price tag.

c) Belt Speed:

Belt speed plays a vital role in terms of making a quality knife. Undoubtedly, you will take more time to make a knife if the knife grinder belt speed is low. Also, you can’t maintain the work if you need to make a lot of knives daily.

On the other side, the machine belt will wear within the shortest possible time if the speed is too high.

It would be best if you decide to buy a knife grinder with an adjustable motor speed option. You can adjust the speed based on your project requirement with these knife grinder types.

d) Belt Size:

2” X 72” belt size is preferable by most professionals, while beginners should choose 1” X 30” belt size. Don’t pick too wide a belt size; your knife-making task will become harder.

To learn about the belt’s direction, look at the belt’s backside. Some belts are manufactured in a one-way direction, don’t buy these belt types. If you don’t find any arrow symbol at the belt’s back, then the belt can move both ways.

e) Sander Size:

Don’t choose a big knife grinder, and the installation process is challenging. The grinder should come with an easy-to-use and carry feature if you do not make a lot of knives daily. Remember to pick a portable and lightweight knife grinder.

f) Dust Collection System:

You may think that a dust collector should not be an essential factor when buying a knife making belt sander. But the truth is, it is a necessary feature of a belt grinder.

You will find knife grinder models in the market that are available with dust-collecting ports. You can make a connection to other vacuums with the help of this collecting port. As a result, you can keep your working area clean.

A few knife grinder models come with a dust collector system, and you don’t need to connect them to other vacuums. Both models are good at delivering the best performance.

g) Fast Performance:

A knife grinder will assist you in removing and shaping material within a short time. This way, a person can quickly make knives.

It is an efficient performer when your task is to remove a large amount of metal from a surface.

h) Cost:

Price is another crucial factor that you can’t avoid. Everyone looks for an affordable option, and you get what you pay for. You have to pay more when you are looking for a knife grinder with many features. A cheap model is not good enough to deliver quality performance.

It is also advisable not to surpass your budget.

Belt Grinder Vs. Belt Sander – What is the Difference:

You can sharpen your tools with both a belt grinder and a belt sander. These 2 machines are the most preferable by professionals for sharpening tools.

Since both tools are used for the same purposes, are they similar, or are they different? Well, let’s look at the below comparison table for more clear understanding.

How to Sharpen Knives with a Belt Grinder?

Instead of using a sharpening stone, people use a belt grinder to sharpen knives for many years.

Sharpening a knife with a belt grinder is pretty straightforward. Remember to wear protective gear while sharpening knives with a belt grinder.

Let’s look at the step-by-step process of Sharpen Knives with the best belt grinder.

Step 01: Arranging all materials

Without a few materials, you will be unable to accomplish this project. Gather the below materials

  • Belt sander
  • Medium grit belt
  • Leather strop
  • Honing compound
  • Dull blade

Step 02: Sander Preparing

Install the medium grit belt into the belt sander. Then select the belt sander direction. When you decide to position the arm horizontally, make sure the belt sander spins opposite to you. And the belt should turn towards you if it spins vertically.

Ensure not to give the belt too tight after loading it. The belt will get damaged if you do so. Also, being too loose is not a good option. Give the belt a medium tightness.

Step 03: Start Sharpening

Hold the knife and start gently gliding into the belt sander. The belt sander should hit the knife’s bevel, so tilt the belt sander slightly. Then follow the same process to the opposite side.

When doing this, ensure wearing hand gloves.

Don’t make a hurry or push the knife to get sharpened quickly. A simple push is enough to get the job done.

Inspect the burr every after few times since the belt sander eats metal quickly; the knife edge may be sharp faster than your expectation.

Step 04: Let the knife cool

During and after the sharpening process, don’t touch the knife edge with bare hands. It is because the knife gets overheated. It needs to get relaxed.

So, after each stroke, soak the blade in water. This way, you can check the sharpness comfortably.

Step 05: Honing the knife

Burring is expected on the blade after sharpening. Honing the knife is the only solution to remove this.

The process of honing and sharpening a knife is similar. Once you give a few strokes, you will find that the burr is removed.

And finally, you will get a razor-sharp blade.
