3 Best 1×30 Belts for Knife Making [Reviewed & Buyer’s Guide]

Whether you’re an expert or amateur knifemaker, 1×30 belts are where it’s at! Their grit range is high enough for knife making, and they’re pretty compact, allowing you a lot of precision.

But my experience as a knife enthusiast, reviewer, and maker over the past 15 years has made me realize that not all 1×30″ belts are created equal. Some are designed for specific materials, while others have broader application scopes.

So if I had to pick an all-time favorite, I’d undoubtedly go for the M-jump 24 Pack belt set because of its versatility, wide grit range, and impressive performance.

But if you’d like some other options, keep reading this review of the best 1×30 belts for knife making on the market today. 

Here Are the Best 1×30 Belts for Knife Making – Tried & Tested

Alright, now let’s put each 1×30” belt under the microscope and compare them in terms of performance, construction, material, and waterproofness.

1. M-jump 24 Pack

Key Specifications

  • Package Dimensions: ‎12.32 x 6.85 x 1.65 inches
  • Item Weight: ‎1.1 pounds
  • Material: Aluminum oxide
  • Grit Range: 60 – 400 grits
  • Longevity Range: 6

The M-jump 24 Pack encompasses grit assortments of 60, 80, 120, 150, 240, and 400 grit, offering four belts of each assortment.

These open-coat M-jump belts are made of aluminum oxide, so they’re suitable for a wide range of materials, including aluminum, non-ferrous metals, wood, glass, stone, and plastic. 

I also like the sturdy connections that these belts have; not only do they make the belts stronger, but they also improve the quality of grinding products. 

In addition, the resin contains an additive for extra load resistance. And the backside of the belts is made of high-quality polyester for extended durability.

However, the only downside to these belts is that centering them on the machine can be tricky.


  • Strong bonds
  • Contains 24 pieces
  • Low and high grit assortments
  • Suitable for a wide range of materials
  • Polyester backside


  • Hard to center


2. Red Label Abrasives 1 X 30

Red Label Abrasives 1 X 30

Key Specifications

  • Package Dimensions: ‎7 x 5 x 1 inches
  • Item Weight: ‎8.3 ounces
  • Material: Ceramic
  • Grit Range: P36 – P120
  • Longevity Range: 6

The Red Labels Abrasives 1 x 30 belt features a ceramic-made design that can handle anything you throw at it; it does a great job at sanding a wide range of materials, from metals to wood and stone.

And the added strength offered by the super heavy-duty Y-wgt material makes the Red Label belt especially useful when working with steel. In addition, the belt has six grit assortments: P36, P40, P60, P80, P100, and P120 grits. 

Moreover, this belt produces little heat thanks to the resin over resin bonding, bi-directional tape joint, and anti-clogging stearate. And since this belt is fully waterproof, you can use it in dry and wet conditions.

The Red Label belt is also quite durable, but don’t expect it to last for years.


  • Made of ceramic
  • Waterproof
  • Durable design
  • Six grit assortments 


  • Questionable longevity


3. Aiyard 1/2 x 18 Inch

Aiyard 1/2 x 18 Inch

Key Specifications

  • Package Dimensions: ‎0.5 x 18 x 0.3 inches
  • Item Weight: ‎5.7 ounces
  • Material: Aluminum oxide
  • Grit Range: 40 – 240 grits
  • Longevity Range: 6

If you’re looking for an affordable set of 1×30” belts, look no further than the Aiyard 1/2 x 18 Inch pack! It features six grit assortments encompassing 40, 60, 80, 120, 180, and 240 grits. Plus, you get four pieces of each grit assortment for extended use.

The open-coat aluminum oxide design is perfect for a wide array of materials. Add to that the heavy-duty X-weight polyester cloth backing, and you’ve got a robust set of belts for knife making.

Moreover, the precision-engineered, bi-directional tape joint, combined with the diagonal lap splice (which gets rid of splice bumps), makes these belts sturdier than most. 

Not to mention that the resin contains an additive that improves load resistance. The belts also feature excellent abrasion resistance and anti-clogging properties. 

However, the pack comes with no directions, which can lead non-experienced knife makers to damage the belts.


  • Additive-enhanced resin
  • Heavy-duty cloth backing
  • 24 pieces
  • Good abrasion resistance 
  • Sturdy tape joint


  • The belts don’t have directions


What to Look For in a 1×30 Belt for Knife Making?

Before deciding on a 1×30 belt, there are some factors you need to keep in mind. These include the motor capacity, longevity range, and waterproofness.

Motor Capacity

Your machine’s motor capacity can significantly influence your belt selection. Motor capacity directly affects the type and amount of work you can do with a particular belt. 

Luckily, most belt manufacturers specify the optimal motor capacity required for their belts to function properly. So make sure to check these specs out before making a purchase.

Longevity Range

The longevity range is the number of grit assortments you get with your 1×30” belt pack. Obviously, the more options you have, the better. 

Low grit assortments work well with chipped blades, while higher assortments are more suited for dull edges. So, having a variety of grits available would definitely serve you better.


Belts that can be used in wet conditions are often better because they usually produce less heat and make for results that are 10x better. 

Not to mention, waterproof belts are way easier to clean and maintain. So, when choosing a 1×30” belt, it’s better to opt for a waterproof one. 

Types of Belts

Generally speaking, there are four types of 1×30 belts to choose from. And while they’ll all get the job done, I personally prefer ceramic belts; aluminum oxide belts will also serve you well if you’re on a tight budget. 


Ceramic belts have the best properties and work with the largest selection of materials. In addition, they’re durable and strong, making them ideal for working with stainless steel knives. 

Zirconia Alumina

Zirconia alumina belts are the best choice for annealed steel because of their self-sharpening properties. These properties also make them suitable for profiling and rough grinding. 

Silicon Carbide

Silicone carbide belts are another great choice for knife sharpening because of their excellent heat dissipation properties. 

Aluminum Oxide

Aluminum oxide is efficient and durable. And it’s most commonly used for woodworking. The main advantage of aluminum oxide belts is that they’re more affordable than their counterparts.

Sanding Belt Grit

Grit assortments determine the belt’s application; 1×30” belts are generally used for knife making, so most of them feature grit ranges from 60 to 400 grits. And the higher the number of grits, the more suited the belt is for knife making. 

How to Use Your 1×30 Belt

There are a couple of things that you need to take care of when using a 1×30” belt. First, look at the directional arrows on the belt when putting it on the grinder.

As a general rule of thumb, start with the lower grit assortments and gradually make your way to the higher ones. 

Lubrication is important, too. Ideally, you need to soak your belt before usage, preferably in honing oil. 

I’d also recommend practicing on a cheap knife first since this process requires a little bit of practice. 

How to Maintain and Clean Your Belt

Whether your belt is 1×30″ or 2×72″, maintaining it is essential to extend its lifespan, especially if you have a closed coat belt; these belts don’t have the self-cleaning properties that open coat belts do, making them more prone to damage over time. 

So here are some of the best techniques to keep your belts in their best condition:

The Belt Cleaner

belt cleaner

The belt cleaner is one of the most convenient ways to care for your knife-making belts. To use the belt cleaner, all you have to do is press it on the belt while the grinder is running to remove any particles of dirt or debris. 

An Old Shoe

If you don’t want to spend extra cash on a belt cleaner, you can use the sole of an old shoe to clean the belt. Any shoe would work, but shoes with crepe soles are preferred because they collect dust more easily. 

To clean the belt with your old shoe, press the shoe sole against the belt like you would with a belt cleaner. 

Specialty Cleaners

Water-based alkaline cleaners do wonders when it comes to cleaning knife-making belts. And they’re very safe to use, too. 

To clean your belt with a specialty cleaner, rub a thin layer of the cleaner with a piece of cloth on the belt and use an air hose to eliminate the dirt particles. 

Store Your Belts Properly

Storage is usually an underrated aspect when it comes to maintaining your belts; if you keep the belts in a contaminated drawer for weeks, don’t expect their condition to be at its best.

Unlike steel knives, which must be stored in leather sheaths, the best way to store your belts is to hang them on conditioning racks, preferably on those with a thickness of 4 inches or more. 

It’s also crucial that your belts don’t touch each other and that the racks aren’t exposed to direct sunlight.


So these were my two cents on the best 1×30 belts for knife making. My favorite pick is the M-jump 24 Pack; it delivers a great value for money as it offers 24 belts with a wide range of grit assortments.

On the other hand, the Red Labels Abrasives belt is more suitable for tougher jobs thanks to its ceramic design. Finally, consider opting for the Aiyard belts if you’re on a tight budget.
