1. Grizzly G1015 Knife Belt Sander

To start off; we have a sturdy and well-built knife sander that will take care of all your needs when making and sharpening knives.

The motor of this knife grinder is not to be taken lightly. It has a 1/3 horsepower motor, which is powerful enough to make a good sharp knife.

The belt speed of this bench grinder is on another level; compared to other models in the market, you can reach 1,725 RPM, which is enough speed to make a knife.

This belt sander has several belt options, which makes it an outstanding choice for polishing knives. Changing the belt is crucial for making knives, which is why we chose this machine.

And if that is not enough, this model gives you a lot of room for making adjustments to the sanding belt. For example, you can move the belt to whatever side you want.

We also enjoy this machine because you can adjust both the arm and the tool rest, making everything a lot easier.

This machine is quite heavy, so getting it out of the box might take a little bit of effort. But because of its bulky design, this model helps offset some of the motor’s weight.

Overall, we believe that this knife grinder is an excellent choice if you’re just getting started, even if you’re a professional looking to get a side knife grinder.

    How to Choose the Best Knife Grinder For Beginners

    Picking up the perfect product for your job is a hassle, especially when you are just beginning. To make your job easier, we have outlined the steps to follow when picking the right knife grinder-

    Why Do You Need a Knife Grinder?

    Although all knife grinders, as is apparent in their name, grind knives, there are different reasons why one would do that. Mainly, there are two categories of people in need of a knife grinder:

    Knife Makers

    Knifemaking can go from being a very artisanal craft to a sophisticated or industrial process. There are several guides and lists of tools for knife making, but a good knife grinder is probably one of the most frequently seen items on the “must-have” inventory.

    Although grinders come in many types and forms that will be detailed further in this article, knife makers should keep in mind that they will need a powerful grinder to guarantee a neat and consistent outcome of their production.

    Knife users

    Most people fall in this category solely for using knives in their daily lives. It is fair to say that people who are not in the knifemaking industry can look at this topic from a more relaxed standpoint and go deeper into the knife sharpening techniques through creative ways of making DIY knife grinders or sharpening kits.

    The main reason for this is that knives – unless they are being made – already have ground. Each grind determines how the blade on your knife functions. Since it refers to what shape the blade is thinned in towards the edge of the knife.

    Taking into account the grind type factor, the following topic is also a decisive point when it comes to picking a knife grinder:

    grinding knife at home shop by a beginner

    What Type of Knife Grinder Should You Pick?

    Different grind requires specific belts to have perfect finish. Before we dive deep, here are the types of grinds-

    Full Flat Grind

    This grind is as simple as it gets. The blade on the knife gets thinner from the spine to the edge evenly on both sides; you’ll notice these kinds of blades in kitchen knives that are intended to go full into, for example, a turkey.

    Hollow Grind

    More popular amongst the hunting fans, the hollow grind knife is concave – making it a good tool for skinning due to its outward cut.

    V Grind

    As implied in their name, these knives have a V-shaped grind that stops halfway down the blade, continuing straight into the handle. It is also known as Scandi Grid due to its Scandinavian origin and mainly used outdoors for woodworking.

    High Flat Grind

    It is another type of flat grind, like the Full Flat and the Scandi, and it is a bit of both. It has the typical entire flat blade at the end of the knife but then acquires a V-shape ground shape mid-blade and finally goes perpendicular into the handle, just like the Scandinavian Grind knife.

    Chisel Grind

    One side of this knife is completely flat, and the other has a single slant that starts halfway down. Also seen in the kitchen, but it is also used in woodwork since it is super sharp. Keeping the edge of that shape can be challenging to maintain.

    Compound Bevel Grind

    Known as Compound or Double Bevel grind, this type of knife has a different angle or slant. It makes cutting more accessible and is less likely to have the blade chip, but given the extra obliqueness, it is inevitably less sharp.

    Convex Grind

    Directly opposite to the Hollow grind, Convex grind knives have a curve rounding to a point, making it ideal for chopping – but also pretty hard to sharpen knives.

    Asymmetrical Grind

    As per its name, an Asymmetrical grind knife has two different grind types on each side of the same blade. Any combination counts as an Asymmetrical grind, and the infinite combinations make for infinite uses of these kinds of knives, as well as different levels of complexity in their dry sharpening.

    All these kinds of grind styles and shapes will require a specific size of the belt in the knife grinder they use, especially those used to make them. It is why if you are a knifemaker, size matters:

    What Size Belt Grinder to Pick?

    The size of a belt in a knife grinder is measured based on its width and length. A 1×30 belt grinder, for example, is a 1″ wide belt that is 30″ long. That said, some of the most common sizes can be found below:

    1×30 Belt Grinders

    Ideal for finishing, not so much to flatten out a blade since they are not wide enough nor have the necessary length to mitigate enough heat to do the work.

    1×42 Belt Grinders

    With similar performance to the previously mentioned size, 1×42 belt grinders are great for dry sharpening. They are also suitable for profiling, meaning they could come in handy when making knives with angles like some of the ones mentioned above.

    2×42 Belt Grinders

    These are good for beginners, really stable and easy to manipulate, but not very good with speed or large knives.

    2×48 Belt Grinders

    They are pretty affordable and compact, making them a good mid-point between a 1×42 and a 2×42 grind.

    2×72 Belt Grinders

    The great thing about 2×72 belt grinders is their flexibility for any kind of knife made since they support most accessories to cover multiple processes. Although they can be too much for someone who is just starting, they are the ideal belt size for a professional knifemaker.

    4×36 Belt Grinders

    The most commonly found and most dangerous for knife making belt grinders out there. Keep these for woodwork, not knife making. They work with weak motors and are too wide to allow the belt’s edge to be used for your knife.  

    There is more to be highlighted on the motor front since not all sanding belt sizes work with any motor power. Here is why:

    How Much Motor Power Do You Need?

    The motor size to pick for knife making depends significantly on the material of the blade you are planning to grind, but especially on the size of the belt you are using. Generally speaking, you need about 1 HP of motor power for every inch your belt measures in width, at 72″ length. Meaning that the longer and broader your belt is, the more power you will need.

    On the material that the blade is made of, there is a factor that is even more determined by it. It is speed:

    How Much Belt Speed to Look For in Knife Grinders

    Grinders are oriented to both knives and woodwork, and wood can be ground with far less speed than, for instance, steel. Depending on the kind of metal you are using, the belt speed will vary. As a reference, your belt should be going at a speed ranging between 4100 and 7000 SFPM (surface feet per minute).

    Plus, you should check for the variable speed feature as you may need different speeds for different jobs. A variable speed machine lets you do a better job.

    Ease of Use

    For beginners, this is one of the most important things to check. An easy-to-use product will let you start working like professionals right from the word go. On the other hand, complicated devices make it hard for beginners to have a perfect finish.

    However, the products we have enlisted in this article are pretty straightforward to use and hence, great for beginners.

    What’s the Price?

    Knife grinder prices differ due to the motor power, sanding belt size, and versatility of the machine in grinding different types of materials.

    A powerful 1-2 hp motor will cost you almost double the price of a ½ horsepower machine, if not more. We recommend going with a mid-level machine so that you can keep working in that machine after you are promoted from a beginner to an almost pro.

    Final Words

    Now that you’ve gone through our long list of the best belt sanders, you now know the best knife grinder for beginner. When you’re first getting started, it is hard to pick up a machine.

    After all, the machine will be by your side for a long time. So you want the knife grinder to be good enough for you to get started into knife making.

    But now, you know what an excellent knife grinder looks like, and how to pick up the right one. And, all those knives you want to make will now come to life.
