Whether your work depends entirely on cutting with a chain saw, or you only use it every once in a while, you’ve probably asked that one question before. How many times can you sharpen a chain saw blade without ruining it?
Your chainsaw’s lifespan depends mostly on its maintenance and the kind of work it’s used for. However, without beating around the bushes, you’ll probably sharpen it 10–15 times before it needs a replacement.

How Many Times Can You Sharpen a Chain Saw Blade?
If you’re a frequent user of chain saws, you shouldn’t start worrying about a change of blades before five years at least. On the other hand, if your use is limited, it could last you decades on end; you might never need a replacement at all.
How often you should sharpen your blades is relative. A general rule is to resharpen it on the second or the third fuel refill. Make sure to sharpen it whenever it becomes dull to keep it in good condition and try to avoid dirt and rocks, which would immediately dull your blades.
That being said, you can sharpen a chain saw blade around 15 times, and then it won’t work. You’ll have to get a replacement.
How to Know that Your Chain Saw Is Dull?
I know you probably think that the breaking point is always how easy or hard it is to cut through the wood using the chain saw. However, you should always consider how much pressure and effort you exert. The ease of cutting isn’t always the clearest of signs.
You could simply check the sawdust. It should be coarse with rough chips instead of fine particles—also, lookout for smoke, which could be a sign of overheating or lack of lubrication. But, if it’s neither of the two, then your saw blades probably need some polishing.
Tips for Sharpening Your Chain Saw Blade
Sharpening the chain saw blades doesn’t only make your life easier; it also prevents kickbacks, potentially dangerous.
For starters, don’t forget to use protective gear, such as gloves and eyewear. Another thing to remember is to turn off your chain saw and to prop it up steadily on a solid surface. Safety comes first!
After that, you might want to check your chain saw manual for the exact sharpening angle and the correct file diameter. If the manual is out of reach, a general file guide is to use a round one of diameter 4mm–6mm.
Tighten the chains, then file from the inside edge of the cutter to the outside part. Don’t rotate the file as you use it, and be careful of the tooth. You don’t want to be pushing them upward or downward as you sharpen them. File until all the teeth are of the same size and the same hook.
The depth gauge teeth or the rakers need to be filed as well, although not as often as the cutters. File the gauge teeth flat to keep your file from damage. Do it in the same direction as the cutter and round any angles that jut out.
With these tips in mind, your blades will stay intact for as long as you use them!
Do’s and Don’ts When It Comes to Chainsaws
Avoid cutting into dirt and rocks at all costs. They won’t only dull your chains in a matter of seconds, but they could also harm other parts of the chainsaw like the chain links. So, it’s best to use a log jack to keep the tree log far enough off the ground.
Furthermore, when the chain blades require change, don’t risk using them further. Consider replacing them as soon as you reach the safety lines marked in the cutters. Any more filing or usage of the blades could lead to the chains falling apart, or worse, flying off. You should also change the chains if the cutters fall off or if they rust.
Also, keep a lookout for the tension in the chains. New ones will need re-tensioning often. Don’t tension them too loosely for safety and not too tightly either, as that would make them prone to wear.
Lubrication is one more thing you should take care of. It’s essential for both the bars and chains. We’d recommend using a high-quality chain or motor oil.
Lastly, never refuel your chain saw when it’s hot; that could be quite dangerous! It could seriously burn up your chain saw or start a fire. Make sure to leave it for at least ten minutes to cool down first.
A chain saw blade would last you a long time before its lifespan comes to an end. However, when it does, don’t hesitate to buy a new one. Always keep safety measures and your convenience in mind.
Taking care of the chainsaw and using it correctly will ensure the blades live for longer.
