Chainsaw Buyer’s Guide Questions

How to Sharpen a Chainsaw Blade

Chainsaws can be tricky to work with. In addition to the skills needed in order to operate a chainsaw safely and effectively, you need to make sure you have one of the best-performing saws to begin with, too. If you’re interested in learning more about how to find the best chainsaw for your needs, be sure to check out our article covering the best chainsaws here.

Otherwise, it’s important that you understand exactly how to sharpen a chainsaw blade. Often, people are quick to run out and buy new blades when their saw becomes dull and ineffective – but knowing how to sharpen a blade will save you tons of money. Plus, it’s a relatively easy thing to do. 

Before beginning, make sure you put on a pair of thick gloves. This will protect your hands while you are sharpening. You should engage the chain brake on your saw so that it won’t slide while you work. Clamp the bar securely so you can use both your hands.

Depending on the type of chainsaw and kit you have, the technique that you will use to sharpen your saw may vary. If you have a manual kit, you will place the guide down on the rivets of the chain. The arrows should face downwards. Then, you will take the file and follow the angle that the guide directs you rotward. After a few strokes, you should see a shiny finish on the metal that will indicate that you are ready to move on to the next cutter.

If you use a bench sharpener, you should set the saw up beneath the device and turn the motor on. The bench sharpener will file down enough of the cutter – you can tell that it is sharp enough in the same way you would when using a manual sharpener. If you choose to use a handheld electric sharpener, you will need to use your guide to get the proper angle. 

Before you are done sharpening your chainsaw, you will need to find a depth gauge to make sure all of your cutters are at the right height. If any of them are not, you should use your sharpener to file them back down to the proper height. That’s all there is to it!

What Angle Do You Sharpen a Stihl Chainsaw?

If you are sharpening a Stihl chainsaw, you will need a bit more precision and accuracy in your task. In order to sharpen a Stihl chainsaw, you should hold your file at a sharp 90 degree angle – in other words a perfect right angle. Guide the file across the cutters at a 30 degree angle, which will give you the same kind of sharpening results that the manufacturers produce on their saws right out of the factory.

What Are the Best Chains for Chainsaws?

Unless you are a professional who has tons of experience handling a chainsaw, it can be confusing to know what kind of chainsaw will be best for your saw. 

In most cases, it will be easiest just to sharpen your chainsaw chain rather than try to replace it. However, if you do need to purchase a replacement chain, you should look for one that’s the same brand as your chainsaw.

This isn’t necessary, but it can ensure a good match. Otherwise, you need to make sure that the pitch, gauge, and length match the existing chain on your chainsaw. You may also want to consider chains from top manufacturers like Stihl, Oregon, and Husqvarna.

Is it Worth Sharpening a Chainsaw Chain?

If you’re reading this article, you’re probably wondering whether it’s even worth spending the time and money to sharpen a chainsaw chain. The short answer to that question? Absolutely.

A chainsaw chain won’t stay sharpened on its own, and it doesn’t take long for a chain to start becoming dull. Even if you don’t use your chainsaw that often, you may find that it begins to lose its sharpness over time. You will need to conduct some regular chainsaw maintenance to keep it operating at its top capacity.

A new chainsaw chain can cost $20 or more – and sharpening your chainsaw costs nothing once you recoup the costs of a chainsaw sharpener. Therefore, this is an investment worth making.

However, not all chainsaw chain sharpeners are built alike. When you are looking for the best chainsaw sharpener, make sure you consider power, as different electric sharpener models will have different motor sizes. The more powerful the motor, the better honing you will be able to do – but the machine willa los be more expensive.

You should look for a high-quality chainsaw sharpener made out of solid materials, too. It would be terrible to spend a ton of money on a chainsaw sharpener after only a few months. Look for heavy-duty  metal construction – not low-grade plastic engineering.

Finally, you will also want to consider the chain size when you are purchasing a chainsaw sharpener. Not all sharpeners can work at any chain size, so you want to make sure you have the perfect fit.

What are the Types of Chainsaw Sharpeners?

There are multiple types of chainsaw sharpeners, all of which can be quite effective depending on the tasks that you need to get done. Electric chainsaw sharpeners tend to be more accurate, as a result extending the longevity of your chain. Manual sharpeners, though generally less expensive, give you a guide to show you the angle at which to file the cutters but they do not do the work for you.

Electric chainsaw sharpeners are fast, efficient, and precise. They require minimal muscle power and although they can be pricey, they are highly effective. 

Within the category of electric sharpeners, there are two subcategories. Bench sharpeners are stationary, as the name implies, while a handheld sharpener requires you to hold it in your hand. Bench sharpeners tend to have a higher accuracy because they give you more control. Since they are stationary, you don’t have to worry about things sliding around. However, they also make it easy to file your chainsaw down too much. 

Thinking about manual sharpeners, you also have two options to choose from. A handheld file is the most basic chainsaw teeth sharpener you will find, and it’s also one of the most commonly used. A handheld file is an easy chainsaw sharpener to get the hang of – all you have to do is run it over the tip of your chain. However, it requires some practice in order to master the technique.

Bar mounted chainsaw sharpeners are also options. These chainsaw sharpening tools are designed for bar mounted chainsaws. You must have a flat platform to use them and you will need to use a hand crank to move your chain through the sharpener.


The most important factor you need to decide on before finding the best chainsaw sharpener for your needs will be in figuring out how often you will use your chainsaw. If you use your chainsaw on a regular basis, you should consider an electric chainsaw sharpener, as it will offer the highest performance over time. Though more expensive, it will be a solid investment.

However, if you don’t plan on using your chainsaw as often, you can probably get away with using a manual sharpener. A handheld file or a similar device will often be all you need in order to get the perfect edge on your chainsaw – so you can get back to the work that motivates you.
