Different Types of Brush Cutter Blades

One of the first things that you will notice when you begin your search for the best brush cutter blade will be that there are many types of brush cutter blade and knowing which one is right for you is essential. Let’s take a look at the pros and cons of the types of weed wacker blades.

Chisel Blades

A chisel blade looks something like a chainsaw chain for weed eaters and features a circular design. While they all look similar, the key difference between each chisel blade is the number of teeth. The teeth are usually made from steel which is a robust material that doesn’t rust and can have a very long life if it is properly maintained.

There are some which perform similarly to a chainsaw and may be the best brush cutter blade for trees and other tough foliage whereas others perform more like a shaver.

While the chisel blade is very effective at cutting through harder materials, you may also find that this makes them a little more difficult to maintain. This is largely because they can be tricky to sharpen owing to the complex shape.

It is also important to keep in mind that kickback is not uncommon when using a chisel blade so we should point out that safety gear such as goggles, leg protectors, face shields and gloves are even more important than usual. You may also notice that a chisel blade tends to get stuck more and may enter material without pulling back.

The best way to prevent kickback with a chisel blade is to avoid cutting through particularly deep brush that measures no more than four inches. This will give you a much safer operation along with a very effective and precise cut.

Knife Blades

The most common and often most affordable type of weed eater blade is the knife blade. You may see a professional gardener using this type of blade since they typically produce the most effective results and are easier to maintain.

The number of knife edges on these blades can vary greatly but as a rule, you would expect to find between two and forty. The amount of knife edges on these blades will tell you a lot about the cutting ability of the product.

One of the greatest things about this type of blade is that it is very versatile. Whether you want to cut through thick brush, weeds or grass, they will tackle most jobs. However, you should think about the type of knife blade that you select especially if you want something durable. For the most part, a star or rectangular option that features a few larger knives will be much more durable and won’t need sharpening as often. However, when it does come to sharpening, the process is much simpler. Furthermore, these blades are great if you are looking for something that can be used for mulching.

In contrast, going for knife blades that have more edges will reduce the likelihood of grass and weeds becoming tangled which is a problem in blades with fewer knives.


A smasher is a great option if you want something low maintenance as these blades do not need to be sharpened. They are also great for mulching. However, you should consider that despite their powerful smashing action, they may not be as great for taller grasses and weeds since they may get tangled easily.

Cleaning the blades is as simple as rinsing away any debris. When you couple this with a lack of sharpening, they are a very convenient option.

Are Brush Cutter Blades Universal?

When you purchase a string trimmer, you will notice that there is normally an option to insert a brush cutter blade and vice versa. Furthermore, when it comes to choosing a brand of brush cutter blade, there are many universal options on the market. However, this isn’t the case for every blade so you should check the compatibility before committing to a purchase.

Brush Cutter vs String Trimmer

To the untrained eye, a brush cutter and string trimmer may look like very similar pieces of equipment and in part, they are. They look alike and both are used for cutting parts of the garden that a lawn mower would have difficulty in tackling. But that is where the similarities end. In fact, there are some significant differences between the two, so let’s take a look.

One of the greatest advantages of a brush cutter is that there is the option to attach a variety of different heads which can be used for many different purposes. For example, you could add a wire which would allow you to perform tasks that would typically be achieved with a string trimmer. However, if you attempt to install a brush cutter blade on a string trimmer, you may find that the engine doesn’t harbour enough power to get the job done. That being said, the right type of weed cutter blade can make the world of difference.

In addition to this, the string trimmer is nowhere near as powerful as the brush cutter. This is because, as separate tools, a brush cutter would have a much more powerful motor installed. This is because a brush cutter is used to tackle much tougher and more dense foliage including trees. The power of a string trimmer simply wouldn’t be enough to handle this and these tools are better suited to weeds and grass.

The engine in a brush cutting tool would normally be either a two or four stroke model with a significant level of power and not only does this mean that they are able to easily cut through tough foliage, but they are far more durable to boot. This durability is extended to the body of the brush cutter which is typically made from tougher materials in order that they stand up to the challenging work they are designed for. While a string trimmer is relatively durable when it is used for its given purpose, when it is employed as a brush cutter, it’s lifespan may be reduced.

FAQ About Your Brush Cutter Blade

Husqvarna offer a variety of blades including saw blades that they claim can be used to customise your weed eater. There are also many other customisation options offered by the brand to convert your weed eater into a tool that suits your gardening needs.

Many of the Stihl blades are made from steel and this is because this metal is lightweight yet extremely durable. You will find that almost all bladed garden tools boast a steel blade for this reason.

If you want to keep your weed wacker brush cutter blade in the best condition, it is important to follow a routine maintenance schedule and a critical part of this is keeping the weed eater cutting blade sharp.

This is not a challenging job but should be kept on top of and we would recommend doing this at least twice each cutting season. Although, the less you use the brush cutter blade, the less times you will need to sharpen it.

  • Before beginning make sure that the power is disconnected and there is no chance of an accidental start-up. Also be sure that you have everything you need including a wire brush, soapy water, a metal file, rags and oil.
  • Before you remove the blade, be sure to mark it so that you can put it back in the correct way. Now take the blade out of the brush cutter.
  • Start by cleaning the blade using warm soapy water to remove any mud or debris. Make sure that it is thoroughly dried before moving on to the next step.
  • Ensure that you have protective gear to keep you safe as you complete the sharpening.
  • When it comes to sharpening brush cutter blades, you can use a metal file and make manual strokes or a sharpening machine. You will notice that the weed wacker blades begin to get a nice shine as they become sharper.
  • Once you are satisfied with the result, you can return the blade to the weed eater and get on with cutting.


Using the correct brush cutting blade for weed eater tools is essential if you want to ensure a clean and effective cut. However, with so many options on the market, it is important that you are able to pick out a blade that will meet your needs. We think that this selection of the best brush cutter blade for weed weed eaters contains some of the most powerful and precise options available.
