Just like any other tool, your chainsaw needs regular maintenance if you want it to perform its best, and that includes sharpening the blade. There’s no hard-and-fast rule on how often you need to sharpen your chainsaw, but many experts recommend doing it every time you need to refuel the tool. You can also check its sharpness visually—when the leading edges of the teeth are rounded or out of the required angle, it needs to be sharpened.

There are several styles of chainsaw sharpeners to choose from, including both electric and manual options. Electric models make the task quicker and easier, but they’re also more expensive. However, the price may be worth it if you regularly use a chainsaw and need to sharpen blades frequently. Manual products, on the other hand, require more time and effort, as you have to file the chainsaw teeth individually, but they’ll save you quite a bit of cash.

Here are the best chainsaw sharpeners to add to your workshop.

If you have a spacious workbench, you may want to have your chainsaw sharpener mounted right onto the surface, and the Blue Max Electric Chainsaw Sharpener is designed to do just that. This bench-mounted sharpener runs on 120-volt power, and it can also be mounted to the wall or a vise—just be sure it’s installed properly, otherwise you may run into vibration issues.

This chainsaw sharpener can be tilted up to 35 degrees on either side, and it delivers a 4,200 RPM grinding speed. It comes with a 4-¼ inch sharpening wheel with a 7/8-inch arbor and can be used on any brand of chain, but keep in mind that it does require you to remove the chain from the chainsaw for sharpening—a small price to pay for easier maintenance, if you ask us.

While this tool may take a little while to figure out, once you get the hang of using it, the sharpener will allow you to easily restore chains to their optimal state.

Best Speed: Garrett Wade Quick Feed Chain Sharpener

Many electric chainsaw sharpeners require you to advance the chain manually, which means you have to stop and move to the next tooth—a somewhat painstaking task. However, the Garrett Wade Quick-Feed Chain Sharpener solves that problem thanks to its system that helps you quickly and precisely advance the chain, allowing you to sharpen a chain for a 20-inch saw in around four minutes.

This chain sharpener is designed to be mounted to a bench, and it comes with a 4.5-millimeter grinding wheel. The company says it typically takes around 5 minutes to complete the initial setup, and after that, you’ll be able to fly through the sharpening process, getting back to work faster. 

Final Verdict

For regular chainsaw maintenance, the Oregon Bench/Wall-Mounted Saw Chain Grinder (view at Amazon) can sharpen chains of various pitches and from many popular brands, making it a must-have in the workshop. However, if you only need to sharpen chains occasionally, the Powercare Electric Chainsaw Chain Sharpener (view at Home Depot) is a more affordable handheld option that can sharpen three common chain pitches.

What to Look for in a Chainsaw Sharpener

 Frequency of Use

How often you use the chainsaw and for what type of wood determines how often you need to sharpen it. Electric sharpeners are easier and quicker to use than manual chainsaw sharpeners, but they are also a bigger investment that might nor might not be worth it for you.

For occasional chainsaw sharpening, a sharpener that comes with all the necessary accessories, such as several sharpening stones and files, makes more sense because you don’t have to start shopping for those accessories. 

Ease of Use

Especially electric sharpeners each have their own, unique system that can take time getting used to. Some electric chainsaw models require removing the chain to sharpen it while others let you sharpen the chain in place, which saves you an extra step. Another convenient feature is when the chain advances automatically, instead of requiring you to move from tooth to tooth by hand.

A manual sharpener allows you to sharpen a blade anywhere but if you are an occasional chainsaw user, that might be a time-consuming distraction. It is better to own 2 or 3 chains and sharpen them back in your basement or garage.

Versatility

Before you purchase a sharpener, make sure it can be used for your chainsaw brand and your chain gauges, as not all sharpeners work for any given model. For heavy chainsaw users who sharpen their chains often, variable speeds can also be a plus. 

Space

How much space you have can determine whether a wall- or bench-mounted or a hand-held sharpener works best for you. If space is an issue and you want a sharpener that you can take with you to your wood cutting jobs, a compact and portable sharpener might be the best option.

FAQ
  • How do you use a chainsaw sharpener?

    As there are many different models of chainsaw sharpeners, and they all work slightly different, follow the directions in the chainsaw sharpener user manual. The individual steps of examining the chain, determining the angle, filling the chainsaw teeth, and filing the depth gauges are described here.

  • Is it worth it to sharpen a chainsaw?

    Yes, definitely, because on average a chainsaw will stay sharp for no more than a saw, and not using a sharp blade is dangerous to the operator, adds to the operator’s fatigue, and wear-and-tear on the chainsaw. Whether it is worth sharpening it yourself depends on how often you use the chainsaw. Sharpening takes time, and it requires its own skill set. Getting the hang of how to use a chainsaw safely and efficiently and cutting wood might be a better use of your time than learning how to sharpen it if you have a service nearby that can do the sharpening for you quickly and at a reasonable price. It might be easier and more efficient to have several chains and have half of them being sharpened elsewhere while you use the others in the meantime.

  • How long should a chainsaw stay sharp?

    It depends on what you are cutting. Hardwoods wear a chain out much more quickly than softwoods like conifers. Also, large-diameter trees dull a chain more quickly than small diameter. If you are cutting large hardwoods for a full day, you might need to put on a freshly sharpened chain during the day. Generally, it stays sharp for 4 to 6 hours of cutting. If you hit a rock or metal, the chain is often damaged beyond sharpening and must be discarded and replaced.
