What to Look for in a Chainsaw Sharpener

Before you can choose a chainsaw sharpener, there are some important things to understand. For  instance there are few different types of sharpeners:

Types of Chainsaw Sharpeners

Handheld File

Perhaps one of the most popular chainsaw sharpening options is also the simplest to use: the handheld chainsaw sharpener or “rat-tail” file. These sharpeners feature a file inside of a guide, attached to a handle.

Before you use this type of sharpener, you need to know the size and diameter of your chain. It’s not a difficult or complicated process, but it’s definitely time consuming work. It can also take a while to learn how to properly file at the proper angle. 

Electric Chainsaw Sharpener

Electric sharpeners are far more efficient at sharpening. They are often setup as complete systems like the Buffalo Tools and Xtremepower models listed above. They can also be setup as attachments to electric power tools like a dremel. 

The full wheel grinder setups are actually rather inexpensive. Same goes for the dremel/die grinder attachments, but these also assume that you own a dremel. These systems are also fairly easy to use and it’s as simple as following instructions. 

Bar Mounted Guide

This type of sharpening tool is attached directly to the guide bar. You will often have to use control knobs to set specific settings like filing angle and sharpener depth.

Once the settings are set you’ll either have to hand crank, or pull the teeth through the guide and proceed to file. These tools are very efficient and won’t cost as much as an electric model. However certain hand crank models like the Timberline can cost double of what an electric option will cost. 

Frequency of Use

If you expect to be use your sharpener fairly often then the electric option will be your best bet. Hand-held sharpeners are the best choice for those people who only have one or two chains or rarely need to sharpen their chainsaws.

Guide bar mounted chainsaw sharpeners are a great middle ground because they offer great precision and have the best longevity. 

Chain Size

Not every sharpener will work with every chain. Some are for a single size and others may be able to adjust through several different sizes. 1/4-Inch, .325-Inch, 3/8-Inch, 1/2-Inch, and 3/4-Inch pitch chains are the sizes you will see the most commonly. Just be sure to check your chain specifications before you make a purchasing decision.

What Angle Should I Sharpen My Chain At?

Manufacturers of chains will suggest the appropriate sharpening angle. You will need to check the manufacturer’s recommendations in your owner’s manual. Most will recommend 30°, but some will suggest 25° or even 35°. 

How Important is it to Maintain Consistent Sharpening Angles on All Teeth?

Very Important. The consistency is important as smaller inconsistencies will mean that your chain is cutting unevenly, this will result in the chain pulling to one side. It also increases the risk of a kickback. 


It is necessary to work with a chainsaw that has a sharp chain. You may prefer to hire a professional to sharpen the chain for you or you can opt to do the sharpening on your own. A dull chain is unsafe to use in the event of kickbacks. It also causes unnecessary strain on your motor.

When dealing with dangerous equipment, you will need to maximize usage while still being safe. A sharp chainsaw is more than just for having smooth and precise cuts; it also eliminates the possibility of your chain being caught up in your logs. If you have a sharper chainsaw, it won’t be prone to creating wobbly movements that can heighten the risk of a kickback. When it comes to your chainsaw’s safety and maintenance, you are only as effective as the accessories that you use.
