Types of Chainsaw Sharpeners

1. Files

Files Chainsaw Sharpener


Files can either be flat, rounded or they can be triangular in shape. Generally, files measure 12 inches in length and are made out of metal.

Each file comes with a different diameter. This helps it to fit easily between the chain’s main brace and the cutting edge of the tooth of the chainsaw.

2. Manual Sharpener

Manual Chainsaw Sharpener


Manual sharpeners are just files that are held by either a metal framework or a plastic framework. This structure helps in holding the file against the tooth of the chain at the precise angle so that when the chainsaw is sharpened, the user has the correct pitch.

Generally, chainsaw sharpeners attach to the chainsaw bar. The manual sharpeners have a handle which you can use to turn or rotate the chainsaw sharpener in such a manner that it comes in contact with the chainsaw teeth.

Manual sharpeners permit the user to sharpen the chain without the user having to dislodge it from the saw. They are portable and small which means that it is possible to take them to the woods with you when you have lots of work to do with the trees.

However, experts suggest that as an owner of a chainsaw, you should own not only a manual chainsaw sharpener but also an electric one. This is because both of them together will help you keep the chains sharpened properly.

3. Electric Sharpener

Electric Chainsaw Sharpener


Electric sharpeners come in a number of sizes. You can either purchase an automatic, full-size chainsaw sharpener which can sharpen almost all of the chains. Or, you can buy mini sharpeners that sharpen a maximum of two chain sizes without purchasing any accessories.

When you are choosing an electric sharpener for your chainsaw, you should look at all of the features that the sharpener has and think about the features that will be useful for you. Buying an automatic sharpener which possesses features that are not useful for you makes no sense. It would only mean that you would be paying money for things that you will never need.

Some of the features that are found in almost all of the electric sharpeners are; being mountable on a number of surfaces like vises, walls, and benches, built-in lights, large knobs and handles; they can sharpen various chain sizes, vises that are self-centering so that the chains are held correctly.

Other features include automated chain feeds, tilting vise heads, big safety guards, fixed angle cuts, safety stops, and different sizes of motors so that various amount of power can be created.

Have a look at the kind of saw that you possess and the chain size that you use. Then determine whether an electric sharpener will be able to accommodate the size of the chain you have or not. The next step is to think about the amount of money you are willing to spend on your sharpener.

Battery Powered Chainsaw Sharpener


4. Battery Powered Sharpeners

These are basically qualified as an electric sharpener, however; they have one advantage over the electric ones. It is easier to carry battery powered sharpeners to the woods and then use the battery of your car as a power source.

On the other hand, sharpeners that are powered by batteries don’t have a powerful motor like the one electric sharpeners powered by standard household electricity have. Moreover, electric sharpeners provide a more accurate edge to your chain.

What to Look For When Choosing a Chainsaw Sharpener?

When you’re in the market to buy a chainsaw sharpener, there are a few things you need to look for.


# Power Source

Take note of the sharpeners power source. Is it battery operated or does it need an electrical source? You should buy an electrical sharpener if you’ll be working in an area that doesn’t have an electrical source.

# Portability

The portability of the sharpener is also important. You should be able to take the sharpener wherever you want. It should also be convenient to store. Try and go for a sharpener that is light in weight and easier for you to carry.

# Ease of Use

A chainsaw sharpener should be easy for you to use. The instructions it comes with should be detailed. There’s no need to buy a sharpener that is cumbersome to use and needs a lot of prep-time before you can sharpen your chainsaw.

# Durability

The durability of the sharpener is another important factor. You need to make sure the sharpener will last you long enough to give you’re your money’s worth.

How to Sharpen a Chainsaw


Here are the steps you should follow to sharpen a chainsaw:

Step 1 - The first thing you need to do is check the depth gauge of the chain. You need to make sure that they’re consistent and the height isn’t too much.

Step 2 - Make sure that the chain’s cutting teeth have an equal length. Use the first tooth as a standard to measure the rest of the teeth. It is recommended that you use a caliper.

Step 3 - Once you’ve sharpened a cutter, only then move on to the next and repeat the steps.

Step 4 - Loosen the vice when you come back to the cutter you started. The guide bar needs to be attached in the opposite direction.

You can see the technique in this short video:

​Take Note:

  • Use smooth strokes to file the cutting tooth. It is recommended that you use two to four strokes.
  • The file guide needs to help at a 90 degree angle to chainsaw bar’s flat face. The normal filing angle is usually 25, 30, or even 35 degrees, depending on the manufactured product.
  • The found file should be placed in the filing gauge. One of the chain cutters should be visibly marked to make it easier for you to know your starting point.
  • Make sure that the chainsaw is secured with a good vice.
  • The chain should be free of debris and dust.
  • To properly use a gauge tool, place the tool over any two cutting teeth. Ensure that the depth gauge slots perfectly into the tool. You need to file down the depth gauge if it happens to stick out
