Why Buy Belt Sanders for Knife Making?

Using a knife making sander, to make knives come with a distinctive advantage of creating a convex edge instead of a concave edge that is made by the traditional techniques. On a shallow look, the traditional knife making techniques seem to have an advantage as metal is shaved away thus creating a sharp edge. However, a closer look reveals that such a technique negatively impacts the integrity of your knives. Concave edges also become duller a little faster than the convex ones.

In a nutshell, a belt sander will help you go through a metal in a way that creates an edge, which retains sharpness for extended durations. Such is an ideal situation necessary for knife making hence the continued increase in the popularity of the belt sanders for such tasks.​

Factors of Consideration in Choosing the Best Belt Sander for Knife Making

a. Size

Two things come to mind when the size of a belt sander is being considered. The size of the sander comes first and is necessary as one has to ensure that they have enough space to accommodate it. The unit also needs to be as lightweight as possible for easy installation. Belt sanders can weigh as little as 20lbs, with some being as heavy as 70lbs. Ideally, the weight of the sander is always proportional to its size or volume. You therefore need to understand the space limitations under your disposal before going for any specific model.

Secondly, the belt size comes to mind when the size of a sander is being considered. A good number of these tools use 1-inch wide and 30-inch or 40-inch long belts. However, the best choice of a belt for knife making would be that which measures 2-inches by 74-inches. You may ask yourself the question why larger belts would be ideal. Larger belts helps you get better sharpening and grinding capabilities as you shape the knife. In addition, the belts are more long lasting because of the bigger surface area that reduces the amount of wear and tear per unit area.

b. Budget

Your budget will always determine what you can go for. But my recommendation is that you shouldn’t go too low. Try and spend as much as you can save. A cheaper unit makes the user to compromise so many services. For instance, you may end up losing the privileges of a superior build quality together with the tracking features if you have a low budget. Leave the cheap units for the newbie. In fact, such cheap units are primarily designed for them to gain experience from.

c. Speed

The belt speed is yet another very critical aspect that must be considered. When gauging efficiency, the primary factor is speed. A belt that moves too slowly takes you longer to do a single piece. Don’t waste your time on such. The bare minimum ought to be 1725 RPMs, with the recommended speed being at least 3000 RPMs. Such a speed makes shaping and grinding faster and much easier.

d. Ease of use

The difficulty of handing any machine is always a point to consider when shopping for one. As far as belt sanders are concerned, do your best to choose a machine that’s much easy to install, to use or even to handle. You shouldn’t spend hours changing a belt. Instead, I would rather you go for one that won’t take you fifteen minutes to change. On the worst, you should take just half an hour.

Similarly, when your choice of machine is that which comes with numerous accessories, these need to be altered as quickly as possible without compromising the efficiency.

e. Motor

The motor power usually gives you a jest of how much power is behind the belt in addition to the overall potential spin speed. The smaller machines features 1/3 horsepower motors, with the bigger models offering 1 horsepower. The bigger the motor horsepower, the more versatile it will be. Such bigger horsepower also offer easy knife shaping and grinding. Just don’t make an assumption that as long as the motor is big, the model automatically becomes better than the smaller motors. You need to know how to balance between motor size, the size of the unit, speed and contact point.

f. Dust collection

Though it hasn’t been a norm, a good number of belt sanders recently entering the market come with some dust collection mechanisms. I would recommend that you consider a machine designed with shop vacuum ports as this helps in the navigation through dust. In any case, as long as a dust collection mechanism is good for your needs and your job, consider going for it.

g. Contact Point

It is prudent that you use a machine with a sufficient plate on which to work. This makes it easy for the user to make all their adjustments without the knife having to hang off the side of the machine. Some belt sanders have been designed with small plates whereas others come with wider ones. This implies that one may need to manually adjust so as to ensure there is enough working room. If your unit of choice has a smaller plate, you may need to weld or affix some wider plates for efficiency purposes.

The best plates also have the ability of tilting up to 45 degrees or even more. Such a tilt is necessary when it comes to the knife sharpening stage. Otherwise, without the 45 degrees tilt, sharpening your knife using the sander won’t be possible. Knife sharpening is the most important part of knife making hence don’t waste your time and money on a unit that can’t sharpen the knife.

h. Tracking

The best belt sanders for knife making are those that feature robust tracking assemblies. Anything less than robustness in this area makes you run the risk of compromising the quality of your project.

i. Frame Design

It is the sander frame that holds all the other components thus allowing the tool to carry out its different tasks. As a result, the best machines are those characterized with robust frames. Go for that machine that features a solid frame as you avoid those with not so good frame materials.


The Kalamazoo 1SM 1725 RPM sander leads the pack as the best belt sander for knife making. The unit has been designed for durability and performance. It comes with a reversible motor and features that ensure versatility. You can thus use the sander for polishing, sharpening as well as sanding among other functions. The Kalamazoo 1725 sander is also easy to use and to maintain and is powerful enough to handle most of your tasks without any issues. The main thing you need to understand is that it’s important you do your thorough homework before setting out to buy a piece. With proper use of this guide, you will hardly go wrong with the sander you end up choosing.
