Our #1 Recommendation: Best Overall

The Oregon 520-120 is a perfect professional chainsaw sharpener that is both powerful and versatile. It rotates the grinding disk at 3400 RPM, making quick work out of 1/4-Inch, .325-Inch, 3/8-Inch, 1/2-Inch, and 3/4-Inch pitch chains.

The Oregon 520-120 comes with 3 different grinding wheels of 1/4”, 1/8” and 3/16” to provide the greatest versatility when sharpening different types of blade sizes.

It also includes a wheel-dressing brick, a template for depth-gauge setting, and a wheel contour.

Another notable feature is the self-centering vise. It automatically aligns to the blade angle and provides a uniform sharpening effect. If you’re looking for a sharpener that is fast, capable of handling multiple chains in a row, and incredibly precise, this is it.

Our #2 Recommendation:

The Buffalo chainsaw sharpener is meant to be one of the easiest electric sharpeners available. After clamping it to a work table, vase, wall, or any stable flat surface, the sharpener can be powered on, and then used to sharpen each blade individually. 

The 60 Hz, 85-watt ECSS boasts a 4200 RPM grinding speed, and plugs into a standard 120-volt wall outlet. It uses a 4-1/4-Inch x 1/8-Inch grinding wheel with 7/8-Inch arbor. It can work with any type of chain blade.

Our #3 Recommendation

This Timberline sharpener attaches to any chainsaw bar and can sharpen individual teeth to the same length and angle. It’s durable, easy to use after you adjust to the feel for it, and is small enough to carry around with you when you don’t want to retreat to your shop for sharpening.

It’s very fast, and is noticeably longer-lasting than similar models.

Timberline does make this in other sizes due to its popularity, but the 7/32” is used more often so we focused on it instead. Here’s the 3/16” version if that’s more suited to your needs.

Types of Chain Saw Sharpeners

Before deciding on the chainsaw sharpener to purchase, there are a few things you need to know first. That starts by learning the three main types of chainsaw sharpeners available.

Handheld File

Perhaps the most commonly used of all chainsaw sharpeners, the hand-held file chainsaw sharpener is also the simplest. Like the name says, it is a round file with a varying diameter that correlates with the size of chain you need to sharpen.

The file is used by running it over the tip of the chain. The process itself is very simple, but it doesnt take some practice, and requires a certain amount of precision for best results. 

Since the sharpening is done by hand, the person doing the actual sharpening needs to be careful to not disturb the cutting angle of the chain. (Source: Family Handyman) One main advantage of these files, aside from the lowest price range, is their mobility.

Here’s a good tutorial on using a hand file.

Electric Chain Saw Sharpener

A much more modernized form of chainsaw sharpeners, the electric chain saw sharpener is the most common used by professionals.

An electric chain saw sharpener is the fastest way to sharpen a dull saw, and usually the easiest to use as well. Those who need frequent sharpening will benefit most. There is a lot of variance among the products you’ll find in this category.

Due to their build and operation, electric chainsaw sharpeners almost always require essential safety gear during use as well, such as gloves, goggles, etc.

Bar Mounted Guide

Bar mounted guide chainsaw sharpeners are not electric, but they are a little more intensive than handheld sharpeners, and require a flat, stable platform to be used effectively, such as a bench or a table. 

With this type of sharpener, you secure the guide to the chainsaw, then mount it on the bar of the chainsaw, and fasten it in place. Control knobs are then used to set the saw per manufacturer’s specifications, which includes the sharpener’s depth and filing angle. 

Once you’re dialed in, a hand crank is used to move the chain through the sharpener. This can cause metal shavings to fly around, so you’ll need protective gear on your hands and eyes. Bar mounted guides are very efficient, and cost less than electric models, but still need to be attached to another surface.

What to Consider When Choosing a Chainsaw Sharpener ?

Accurately choosing a chainsaw sharpener relies on 4 key factors.

Electric Chain Saw Sharpener


Each type has it advantages and disadvantages. Familiarizing yourself with the descriptions above will help you decide on the actual type that works best for your needs.

Frequency of Use

If you’re anticipating the need for sharpening on a regular basis, an electric model may be best. Handheld sharpeners are good for those who either need to bring one with them during a job, or rarely need to sharpen their chains.

Mounted guides offer a lot of precision, and tend to last the longest, but do require a workshop surface.


Deciding on how much you’re willing to spend beforehand will help restrict you to products within a certain range but do know that it’s hard to find quality electric models when on a small budget.

Chain Size

Not all chainsaw sharpeners can handle various chain sizes. Some are restricted to one size, while others may be able to take on multiple sizes if they can adjust. 1/4-Inch, .325-Inch, 3/8-Inch, 1/2-Inch, and 3/4-Inch pitch chains are the most common sizes, so check your chainsaw to make sure you’re getting the right sharpener for it.
