Trying to cut a tree with a dull chainsaw is like using a butter knife to cut steak.
Trying to cut with a dull blade takes forever, plus it puts extra strain on your motor and shortens the life of your saw. This means sharpening your chainsaw saves you time and saves you money.

The Granberg Bar-Mount Chain Saw Sharpener is a highly precise chain saw sharpener. There are plenty of dials to set all the different angles for you to properly sharpen your chainsaw’s teeth.
Because this sharpening system is on a jig, all of your sharpened teeth will be very similar and precise. This is important because manual, or freehand, sharpeners have the possibility of overly sharpening some teeth and leaving uneven angles. This sharpening jig removes the variation between teeth because the jig ensures precise sharpening.
One downside to this chainsaw sharpener is the amount of setup time. There are plenty of screw to tighten and dials to turn but if you can follow the instructions, you will be off to sharpening in no time. The sharpening time should take less than 5 minutes for a whole 16″ bar chain. You will also need to take down the depth gauges after you’ve sharpened the teeth. This could add to the overall setup and sharpening time.
It is great to see a professional, who uses his chainsaw for timbering, recommends this chainsaw sharpener: “This jig also fit the bill because when milling, you will often sharpen many many more times in a day than you would simply bucking and felling. I often work in remote areas and the Granberg is packable.” The full review even gives some tips on the angle of approach which you should sharpen your chainsaw teeth to. Read the full review here.

Electric Chainsaw Sharpeners
The GOXAWEE Chainsaw Sharpener Kit is an easy to use sharpening kit for any chainsaw. It is highly versatile and you can use it on any tool in your shed.
As a chainsaw sharpener it does very well. The angle guide allows you to get the proper angle of sharpening fairly easily. There are multiple grinding stone sizes so you can set it up for the size of your chainsaw teeth.
The one downside is that it takes a bit of adjusting to get the guide positioned to the correct height in reference to the grinding stone. Be sure to read the manual carefully and follow all the instructions. This sharpener also has the potential to shoot sparks because of the high speed grinding. Be sure your work area is clear of ignitable or combustible materials.
Some customers claim the working instructions don’t provide much detail such as this reviewer, “Never used a chainsaw sharpener before and had to go on youtube to search on how these things work. The instructions were a bit lacking on use but the tool itself is great once I figured it all out.” With a bit of help from Youtube, you’ll be able to figure out just how to use this sharpener.

The Oregon 410-120 Chain Grinder is a benchtop grinder which ensures highly accurate and sharp chainsaw teeth. This chainsaw sharpener is electric and pairs well in your garage away from any combustibles.
To use this chainsaw sharpener you will need to remove the chain from your chainsaw and mount it into the guide track of the sharpener. The instructions in the package tell you all the knobs and screw to turn so you may properly secure the chain and grind at the correct angle for your chainsaw teeth.
The drawback to this setup is the time required for setup. Removing the chain from the chainsaw significantly increases setup time. This also means you will not be able to use this sharpener while outside in the woods. Because of the grinding, there is a possibility for sparks, therefore you should ensure all combustibles are safely stored away.
This chainsaw sharpener has plenty of satisfied customers, here is a one review who has a suggestion on how to make this sharpener portable, “The instructions were clear and precise. I screwed a couple of “runners” to the bottom of a 2″ x 6″ board to form a platform for mounting the sharpener, which makes it portable; all I need to do is clamp it to horizontal surface and it’s ready to go. I grabbed a dull chain and carefully followed the directions. The process was quick and easy.” Read the full review here.

DO NOT BUY THIS ONE!!!
The Wellead Portable Chainsaw Sharpener is a chainsaw sharpener meant for a very specific type of chainsaw. Unless you have a chain with a profile like this Oregon PowerSharp chain, then you will not be able to use this chainsaw sharpener. This chain literally has a different shape and is not a traditional styled chainsaw.
There are too many bad reviews of this chainsaw sharpener simply because this chainsaw sharpener is not meant to be used with traditional chainsaw chains. This sharpener files the top of the cutting chisel whereas normal sharpeners requires you to sharpen the interior of the chisel. If this product seems too good to be true then you are right, read the instructions and see if this will match your chainsaw chain.
One review which really stands out is this one of a customer claiming to have sharpened the chain for over 10 minutes, “Attached it to my chainsaw according to the insanely vague instructions, ran the chainsaw against the sharpening stone for 10-12 minutes, removed the sharpener, tried trimming small 2” diameter branches. Nothing.” This chainsaw sharpener takes just a few seconds to sharpen the cutting chisels, do not sharpen for more than 10 seconds.
If you’d like to be able to use this super easy sharpener then check out the Oregon CS1500 18 in. 15 Amp Self-Sharpening Corded Electric Chainsaw. This chainsaw already has a sharpening kit inside the housing but can also use the Wellead Portable Chainsaw Sharpener.
How do I brace my chainsaw for sharpening?
To sharpen your chainsaw outdoors, you’ll need to brace your chainsaw. The best way to do that is by using a stump vice like this Oregon Stump Vice.
- Makes chain and bar maintenance easier for users, especially in the field
- Fits in your pocket for easy access when you're on the move
- Handy and goes anywhere
If you prefer a bench vice, there are many options to choose from. There are portable options which you can clamp onto a two by four or permanent vices which you drill onto your workbench.
How often should I sharpen my chainsaw?
Chainsaw sharpness is fairly easy to tell. The majority of the wood you shave off should come out in ribbon like strips. The longer the ribbons, the sharper the teeth. As soon as you start having sawdust appear, you should sharpen the teeth on the chainsaw.
A sharp chainsaw allows you to conserve fuel and be efficient with your cuts. A dull chain means longer cutting times and more fuel wasted. It can also shorten the lifespan of your saw because there is more strain on your motor. Holding a chainsaw for more than a few minutes can be grueling, since most weigh around 10 pounds. Having a sharp chainsaw is essential.
Getting the right chainsaw sharpener
Do you need a portable chainsaw sharpener
Portability can be a deal breaker for some folks. If the chainsaw work you do often has you far from your tool shed, then you probably want a more portable chainsaw sharpener. Having the ability to sharpen your chainsaw while out in the field is a great luxury especially if you accidentally dull the teeth and absolutely need to cut into a tree.
Ease of use
Some chainsaw sharpeners have way too many settings to remember. The simple the easier, I believe. If you don’t mind reading the instructions each time you operate the chainsaw sharpener, then you already know which is best for you. If you want a chainsaw sharpener that is ready to go right out of the box, then the Stihl 2 in 1 chainsaw sharpener is the choice for you.
Time required to set up a chainsaw sharpener
The time required for setup and sharpening is obviously something you should consider. The quicker, the better. Be cautious of the chainsaw sharpener which you need to remove the chain to sharpen. This can lead to a really long day just to get your chainsaw sharpened.
You won’t need to gas up any of these chainsaw sharpeners but you may need to change out a file or a sharpening stone every once in a while. Whichever chainsaw sharpener you choose, you should familiarize yourself with it so that you understand what maintenance it needs and how to tell if its time to replace any of the pieces.
Sharpening your chainsaw is highly gratifying and you should feel proud of doing so. Understanding the angles and being aware enough to properly sharpen your chainsaw is something not many people know how to do these days. Remember to keep good care of your tools by cleaning and storing in a dry place after using.
