What Is a Chainsaw Sharpener?


A chainsaw sharpener is a tool for renewing the cutting edge of a chainsaw chain. It can be manual or electric-powered. A blunt chainsaw cannot cut anything. And if you try to use the saw in a dull condition, work becomes harder and riskier.
You can find an array of chainsaw sharpeners on the market. Some come in a filing kit you operate manually; others have a mechanism that fit any chain type, and you can buy electric types which work on a vise you can mount to a table or wall. Whether you are a professional or occasional user, a chainsaw sharpener is an essential tool if you want to maximize the potential of your saw. But having a quality chainsaw sharpener is not enough; you need to know how to use the tool correctly.

Chainsaw Sharpener Buying Guide

Chainsaw sharpeners are essential tools for everybody who owns a chainsaw. Whether you are a professional who works with a chainsaw daily or the occasional homeowner with a wooded lot, you need a chainsaw sharpener to get maximum value from your cutters. If you are shopping for a high-quality chainsaw sharpener, this buying guide shows the factors that can help you make an excellent choice.


What to Consider When Buying a Chainsaw Sharpener

When you go shopping for a chainsaw sharpener, the following are vital considerations to make a worthy investment.

  1. Frequency of Use

    It is important to think about how often you will use the chainsaw sharpener before buying one. If you are an occasional chainsaw user who only files his chain occasionally, you can go for a simple and cheap file kit. However, a lumberjack who cuts trees every day will need a chainsaw sharpener that automates the chain filing task, reducing time spent on sharpening, increasing productivity, and eliminating complexities.
    Professional woodcutters may require industrial sharpeners designed for heavy use. Simple commercial sharpeners may also be ideal but can’t stand the rigor of daily wear and tear which professional tree fellers require performing their work. If you use a chainsaw for pruning or limbing the few trees on your yard twice in three months, a manual chainsaw sharpener may be ideal for your needs.
    Whatever your decision, buy a chainsaw sharpener with the design and durability for the frequency of the sharpening tasks you hope to perform. That will help you maximize the value of your purchase.

  2. Price

    Price is an important determinant in the buying process. Based on your needs, make sure not to sacrifice quality over price considerations. While it’s essential to buy a chainsaw sharpener within your budget, it is vital to choose a model or brand with all the features you need. You might end up paying a little extra for the ideal tool, but you will enjoy your investment in multiples.

  3. Power

    Power is a critical consideration when buying a chainsaw sharpener. Chainsaw sharpeners can be manual or electric-powered. The manual chainsaw sharpener can be as simple as your regular flat or round file you operate manually or the bar mounted versions.

    The problem with manual sharpeners is that they need an enormous amount of skill, control, and precision to deliver a perfect grind. If your mind strays while filing the cutters with a manual chainsaw sharpener, you can ruin the chain, forcing you to buy a new one. Bar mounted manual versions are easier to operate and deliver a better job compared to handheld options.

    The electric-powered versions offer the highest level of precision and accuracy, power, and versatility. These tools can adjust to most chain sizes and increase chain length by removing a small part of the chain. With an electric chainsaw sharpener, your work becomes faster, safer, and more efficient. When buying an electric chainsaw sharpener, look at the RPM rating; the power is proportional to the engine’s RPM.

  4. Speed

    Nobody wants to spend all day filing a chain in a workshop. And that’s why you need a sharpener that can deliver within a short time with relative ease. Electric sharpeners are the fastest and most efficient way of giving your chains a new cutting edge, but they can be expensive. You can also buy a bar-mounted sharpener to reduce time spent on sharpening cutters.
    If you cut trees for a living, go for a high-quality sharpener that allows you to get more work done with minimal energy and expenses. The faster the better so you can concentrate more on real work; which is what really matters.

  5. Compatibility

    If you intend to buy a manual sharpener, you need to buy an option compatible with the size of your blades. Remember that rounded hard files are suitable for particular types of chain cutters, so buy a file perfect for your chain size.
    Most electric powered sharpeners are suitable for almost every type of chain size, making them the ideal choice if you can afford it. If you work with a variety of blade sizes, you are better off buying an electric chainsaw sharpener. The electric version may be costlier, but it is well worth it regarding versatility, speed, precision, and accuracy.

  6. Durability

    The best chainsaw sharpeners feature top grade materials and construction. It’s best to buy a sharpener made from heavy-duty machined metal as they are more durable and able to cope with rough handling. There are sharpener options made with plastic and other fragile materials, but these types sacrifice functionality for aesthetics. Go for a functional sharpener with a sturdy design; not a beautiful product that won’t last a season.

  7. Safety Mechanisms

    When buying a chainsaw sharpener, go for options with built-in safety features, especially if you are a heavy chainsaw user. It’s also important to get a machine easy to operate. This will make your work faster and reduce the risk of injuries.

Types of Chainsaw Sharpeners

There are three types of chainsaw sharpeners, including:

  • Handheld sharpeners
  • Bar-mounted Sharpeners
  • Electric Sharpeners
  1. Handheld Chainsaw Sharpeners

    These chainsaw sharpeners are the simplest form. It consists mostly of rounded files which you can operate by hand to sharpen the cutters on your saw chain. Handheld options require skill and control to file the teeth of the chain.
    Handheld sharpeners are not as versatile as each file is only compatible with certain blade sizes. However, some manufacturers like Katzco provide a full kit with a variety of files for every type of blade possible. Handheld sharpeners have low precision and accuracy, making it difficult to achieve a consistent sharpness across the cutters. If you are skilled enough to control the handheld sharpener, it is the cheapest you will get on the market.

  2. Bar-mounted Sharpeners

    Bar-mounted sharpeners are manually operated but deliver better functionality compared to handheld options. They need a flat, stable surface like a table or bench for maximum effectiveness. As the name implies, you only need to position the device onto the bar of your chain and run the blade over it to get a sharp edge.

    A bar-mounted sharpener is more precise and accurate and the edge of your blade will be more uniform, but you must adjust the device correctly to the chain size and the device’s filing angle and depth. This option is more affordable compared to electric units. Remember to wear hand-eye protection goggles before using a bar-mounted chainsaw sharpener as it throws off metal shavings during operation.

  3. Electric Chainsaw Sharpener

    The electric sharpener is the most sophisticated device for transforming dull blades to sharp cutting edges. Most professionals prefer electric sharpeners because it is ideal for any chain size and delivers exceptional precision and accuracy. Electric sharpeners are fast, efficient and offer a professional finish that will increase your productivity.

    To use an electric unit, all you need do is place the chain inside the machine, adjust the settings and sharpen.  However, these tools also need the operator to use safety equipment such as goggles, hand gloves, among others. The only downside is the higher cost, but electric chainsaw sharpeners deliver exceptional value for professionals.

Features of Professional Chainsaw Sharpeners

If you are a professional chainsaw user who intends to buy a top quality sharpener, you need to check the following features regarding your work requirements.

  • Settings

    It is vital to check that the sharpener comes with default settings that make your work easier. Some high-quality brands leave you to figure out the ideal settings for each chain type, and this takes time. Double check your sharpener has preset templates that allow you to work efficiently regardless of the blade type you want to sharpen.

  • Mounted or Portable

    If your work requires being mobile every time, it is advisable to purchase a portable sharpener so you can sharpen your blades anywhere, anytime. However, mounted or bench-top sharpeners are perfect for people who work in a fixed location. Sometimes, it’s possible to fix a bar-mounted sharpener to a board and carry it around. The bottom line is to choose a sharpener that gives you the ability to sharpen your dull blades when you need it.

  • Assembly

    Assembling and setting up your chainsaw sharpener may be simple for people familiar with power tools and other mechanical devices. However, people without such backgrounds can find it difficult to assemble or fit the device to a work surface. If you are the latter, make sure the model you choose comes in a simple design that won’t leave you wracking your head for ideas.

  • Attachment

    Attachments can multiply the utility of your chainsaw sharpener. If you work with different blade sizes, you need a sharpener with over one wheel size to accommodate the various chain sizes. A sharpener with 2 or more wheel types is ideal for professionals.

How Does a Chainsaw Sharpener Work?

How a chainsaw sharpener works depends on its source of power; manual or electric. Manual chainsaw sharpeners depend on a guide that shows the user the correct filing angle. With the angle set, you move the file across the guide to sharpen the cutters.

Electric chain sharpeners use a different mechanism. Electric chain sharpeners can either be handheld or a bench and wall-mounted sharpeners. The wall and bench sharpeners are stationary while you hold the handheld sharpener in your hand during operation to sharpen your saw’s chain.

Electric sharpeners are more accurate and precise for sharpening chainsaws and also improve blade life because they remove only a small portion of the chain. Also, bench sharpeners are more accurate compared to handheld electric sharpeners because it is stationary, improving control and precision.

You use a forward and backward hand movement to file the cutters when using manual sharpeners. But you only need to fix the chainsaw to the electric unit and turn the motors to sharpen the cutters and repeat until the sharpening is complete. The electric variant is also faster than the manual sharpeners and makes your work faster and more efficient.

You need total concentration while filing a chainsaw, especially when you are using a handheld sharpener. If you file too high or too low, you can damage the chain or make it too sharp for use, increasing the risk of injuries. Make sure you get the correct angle and pay attention to avoid ruining your chain.

When and How Often to Sharpen Chainsaws

How often should you sharpen your chainsaw? This question is common in many online communities where hobbyist chainsaw users meet to share ideas. There are many answers to this question, but one stands out; it’s time to sharpen your chainsaw when you need to apply pressure before the machine can cut through wood.

In its ideal condition, a chainsaw cuts through the wood in a smooth and effortless motion. If you apply pressure or force it to enter the wood, then your chainsaw is dull and needs sharpening.

A lot of factors can determine the frequency of sharpening. The wood you cut, the cuts, and the size of trees you fell are factors that affect the wear and tear on your chain. If you cut clean wood for several hours of continuous use, you may need to sharpen the chain after the work.

Cutting through dirt or sand or any other uneven surface dulls the cutters quickly, causing an immediate sharpening if you want to continue working with high efficiency.

So, if your chainsaw won’t cut without additional effort from you, or the debris from the cut looks more like sawdust instead of chips, then it’s time to sharpen that chain. A dull chain not only makes your work harder, but it also increases the risk of kickbacks and other chainsaw accidents. Your chainsaw requires only a little help to do its job unless the chain is dull.

Chainsaw Sharpening Tools

Chainsaw sharpening tools come in a diverse range of designs and constructs. Here are the common chainsaw sharpening tools popular among professionals and hobbyists.

  • Round files
  • Flat files
  • File handles
  • File handle and guide
  • Filing guides
  • Stump vices
  • Depth gauge tools
  • Easy file
  • Sharpening pouches
  • Grinding stones
  • Grinders

How to Sharpen a Chainsaw

In the hands of a skilled user, a chainsaw sharpener is simple to use. However, a novice can damage the blade if he does not know the correct technique of sharpening a chain. Below are steps to follow when using an electric or manual chainsaw sharpener.

How to Sharpen a Chainsaw with an Electric Sharpener

  • Inspect the shape of the grinder wheel.
  • Set the vise assembly to the correct top plate filing angle if there is no present template. Otherwise, use the default setting of the device.
  • Set the correct grinder head angle using the top-plate cutting angle recommendation of the manufacturer.
  • Check that the chain is blocked and screw the vise blocking handle tight.
  • Power the electric sharpener.
  • Lower the arm-motor unit to sharpen the blade.
  • Raise the arm and loosen the handle when the sharpening is complete.
  • Run the chain forward to place the next cutter in position for sharpening.
  • Repeat the process above until you have sharpened all the cutters.

How to Sharpen a Chainsaw with a Manual Sharpener

  • Hold the bar in a vice while the chain brake is activated.
  • Position the guide between the rivets of the chain so that the guide’s arrows point toward the bar nose.
  • Start filing from the top plate of the cutter and make sure not to grind the side plates excessively as this will reduce the blade’s efficiency.
  • With 2-3 steady, even strokes; file the cutter until you see a shiny silver face.
  • Once you are done with one side of the blade, disengage the chain brake to flip the other part of the chain for sharpening. Now, reactivate the chain brake
  • File the other side when you are through with sharpening one side.
  • Adjust the chain’s depth gauge height with a depth gauge tool. The depth gauge must not be too high to ensure the blade has maximum contact with the wood surface.

Whenever you sharpen your chainsaw, clean off debris from the chain surface and then use bar and chain oil to lubricate the chain thoroughly. Soak the chain overnight for optimal results so you are ready to rumble on the next task.

Chainsaw Sharpening Angles

Chain manufacturers fit the cutters to the chain at specific angles, and you need to consider the angles when sharpening the blade. Each tooth has two angles in the top plate and side plate. It is essential to maintain the following angles when sharpening a chainsaw.

  • Inside Top Plate Angle: The ideal sharpening angle for the inside top plate is 30˚ to 35˚ if you cut clean and soft wood. But you can make the angle blunter if you cut hardwood to increase the edge strength of the blade and improve longevity.
  • Outside Top Plate Edge: The appropriate sharpening angle for the outside of the top plate edge is 15˚ to 20˚.
  • Outside Side Plate Angle: Sharpen the outer side plate angle at angles 85˚ to 90˚ to improve cutting efficiency.
  • Inside Side Plate Angle: The ideal sharpening angle for the inside side plate angle is about 45˚.

Chainsaw Sharpening Tips & Tricks

Sharpening a chainsaw to the ideal depth and angle takes practice. Here are tips to keep your chain saw sharp.

  • Wear protective gear like hand gloves, long sleeves, goggles, and hearing protection if you use an electric sharpener.
  • Use a sharp file that matches the size of your chain.
  • Oil your file before storage.
  • Use your depth gauges every time.
  • Clean your chain before sharpening.
  • Inspect the chain for any damage or wear and tear. If the chain is damaged, it’s better to repair it to avoid injury and low productivity.
  • Place the chainsaw sharpener on a stable and steady surface to avoid slips and accidents.
  • Use both hands while operating a chainsaw sharpener.
  • Hold the chain in place with a vice.
  • Make sure the chainsaw is not connected to the power source if you are sharpening the chain in the chainsaw bar to avoid accidental starting that could lead to injuries.


  1. When to replace the chain
    It’s time to replace the chain on your chainsaw when:

    • It pulls itself into the wood.
    • The chain runs in one direction.
    • The chain bounces or rattles around when cutting.
    • The chain-smokes when cutting, even when everything is in order with the chainsaw.
    • The chain is making sawdust instead of wood chips.
    • The chain is missing teeth.
      Make sure to also check out our chainsaw chain buying guide.
  2. Should you buy a manual or electric sharpener?
    People who sharpen frequently can buy electric sharpeners as it is faster and more accurate. A manual sharpener is sufficient for the occasional chainsaw user.
  3. When should I sharpen my chain?
    Sharpen your saw when it produces sawdust, no longer self-feeds, or you need to exert pressure on the saw to cut.
