What is the best chainsaw sharpener, and what type do you need for your saw?

Chainsaws are vital tools for tree removal, pruning, and cutting firewood, but many of us don’t realize how quickly the chainsaw blades dull.

To make using a chainsaw as safe and efficient as possible, you should always keep the blades sharp.

Whether you prefer to get this done as fast as possible with an electric sharper or take your time perfecting each edge by hand is up to you, but in either case, you’ll need the best tool for the job.

Chainsaw sharpeners can be broken down into four classes: handheld manual, bar mount, handheld electric, and electric.

The best chainsaw sharpener for you may depend on the type of chain you have – though some sharpeners are universal, in which case they should be able to sharpen all chainsaw chains.

Handheld Manual

This category includes any handheld files where you have to sharpen each tooth manually.

Manual handheld sharpening kits often come with multiple round files, a flat file, and sometimes a filing guide.

The round files are for sharpening the teeth, the flat file is used to lower the raker, and the filing guide helps the user maintain the proper angle on the tooth while filing.

Bar Mount

Bar mount files are similar to handheld files, but they use a rig that clamps onto the chainsaw to keep the filing angle consistent. The rigs are adjustable for different types of chains and help to speed up the manual filing process.

Bar mounts can be quite bulky, but they help maintain a better angle.

Handheld Electric

Handheld electric chainsaw grinders are essentially small dremels. They spin rapidly to emulate the movement of a handheld file.

Some handheld electric grinders have different Dremel attachments and built-in filing guides, but not all of them. As long as you have a power source, these tools can help save your arms the strain of filing.


Electric chainsaw sharpeners resemble miter saws. They are usually bench or wall-mounted and can greatly increase the speed at which you can sharpen a chainsaw blade.

Electric grinders have a wide range of adjustments and options and can sharpen blades like a pro. Of all the sharpeners, they tend to cost the most.

*Even a universal sharpener may not be suitable for a mini chainsaw.

How Chainsaw Sharpeners Work

what is the best chainsaw sharpener

Sharpening chainsaw saw blades work the same way sharpening any other knife edge does. Whether you are sharpening by hand or with an electric sharpener, the device works the same.

When the blade edge starts to dull, it means that the point has worn down enough to round out; there is no longer a cutting edge.

By abrading the surface at an angle with a harder material, you can grind down the blade until the edge is sharp again. It’s the same process as filing your nails.

By filing your nails you are sanding off the sharp edges by moving the nail file in a round motion. To sharpen a blade, you move the file in a linear motion along the blade. Your nail would end up just as sharp if you followed a linear motion on them too.

How to Choose the Correct File/Sharpener for Your Chain

Figuring out the right file size to sharpen your chainsaw chain can be headache-inducing.

You can watch several lengthy videos on how to calculate the pitch of the chain, or you can just look at some simple sizing charts.

For everything, you need to know about chainsaw chains, including how to determine file size, check out STIHL’s sizing chart.

Manual Vs Electric Chainsaw Sharpeners

stihl electric chainsaw sharpener

Manual sharpeners offer more control over the angle, sharpness, and level of grind than electric sharpeners do, but they take a lot more effort.

To use a manual chainsaw sharpener, you have to have a steady hand, good technique, properly sized tools, and patience.

Electric sharpeners save time but don’t work with all chain sizes and can sometimes grind off more material than they need to. They are more reliable, however, and provide your arms with much-needed rest.

Manual sharpeners tend to be easier to transport than electric, but some electric sharpeners work on the go.

Best Electric Sharpener Features

All the best electric chainsaw sharpeners have a few things in common that make them better than other sharpeners.

That includes:

  • Quiet operation
  • Easy/comfortable to use
  • A powerful motor

The best features an electric sharpener can have are things that improve how the device works and ensure consistent and efficient grinding.

The very best chainsaw grinders have:

  • High-quality grinding disks
  • Accurate angle guides
  • A wide range of settings and positions
  • Sturdy build
  • Consistent and quality results

As with anything, you get what you pay for, and the more expensive models are better than the cheap electric chainsaw grinders.

Free Hand Filing Vs Bar Mounted Sharpenersbest oregon chainsaw sharpeners

Many professionals prefer to use handheld manual filing instead of bar-mounted sharpeners because it saves time and effort.

While bar mounts help with consistency and accuracy, they take time to set up and use. If you have a precise enough skill level, filing by hand may be faster.

For novices and those bad at judging angles, however, bar mounts can save your chainsaw blades.

When you’re just starting out, it can be best to use a bar mount but have a goal to eventually sharpen your saw freehand. You won’t be amazing at it overnight, but after a bit of practice, anyone can become good at it.

Chainsaw Sharpener FAQs

What is the best brand of chainsaw sharpeners?

Oregon and STIHL sharpening tools are regarded as some of the best chainsaw chain sharpeners on the market.

They make consistently good tools that work as advertised and last ages. STIHL chainsaw sharpeners tend to have a better reputation overall, but can be pricier compared to Oregon chain sharpeners.

How do professionals sharpen chainsaws?

A lot of professionals prefer to sharpen their chainsaws with a hand file.

A well-maintained and frequently sharpened chainsaw only takes a brush or two per tooth with a file to stay sharp. Some pros do like to use electric chainsaw sharpeners and bench-top ones, but portable options are easier to find in professional settings.

What is the best way to sharpen a chainsaw chain?

If you are filing by hand, you need to keep steady pressure on the file and only push it in line with the edge.

Don’t pull the file back across or twist it. File every other tooth in the direction of the blade towards the point, and then flip the saw to do the teeth that face the other way.

For full details, watch the video tutorial above.

Do electric chainsaw sharpeners work well?

Electric chainsaw sharpeners, sometimes referred to as chainsaw chain grinders, are a quick and easy way to sharpen a chainsaw. Gone are the days of sharpening each cutting edge by hand; electric sharpeners make the job much faster.

How often do you need to sharpen a chainsaw?

The frequency with which you need to sharpen your chainsaw varies greatly depending on what you are using it for.

On average, you should sharpen it after 10 uses. It is always safer to work with a sharper blade so if you can’t remember if you have used the saw 8 or 9 times, sharpen it anyways.

What size file do I need to sharpen my chainsaw?

Files usually range from 4-5.5mm but you may need a larger or smaller one for your chainsaw.

If you look on your chainsaw bar you should be able to gather the details on what type of chain you have, which will then tell you what type of file you need.

Why does my chainsaw blade get dull so fast?

Aside from regular use, many factors could be dulling your chainsaw blade faster than normal. Too steep an angle on the cutters tends to dull blades quickly. 25-35 degrees is ideal for most uses.

Having too deep a cutting angle or having the rakers too far down will also wear down the blades faster.

The type of wood, the dirtiness of the wood, and outside obstacles can also have an effect. If the wood is too hard, too dirty, or you are catching ground when you cut, then the blade will wear down faster.

Is a dull chainsaw blade ever good?

Yes, if you are juggling chainsaws, you don’t want the blades to be too sharp!
