Want to learn how to sharpen a chainsaw blade with a file? Here’s our guide.

  1. Select your tools “There are many different files available specifically made for sharpening chainsaws. They’re affordable and easy to use,” says Melody Estes, Landscape Gardening Supervisor from Maine and a consultant at The Project Girl (opens in new tab). Check your manual for the recommended size. Equip yourself with a round file for the teeth and a flat file for the rakers.
  2. Prepare your chainsaw Clamp your chainsaw to the surface to steady it. Tighten the chain. Mark the first tooth with a pen to know when you’ve reached it again.
  3. Sharpen the teeth Your chainsaw has two types of cutters - forward and backward-facing ones. File all of one type and then the other. “You need to file in a way that doesn’t damage the chain,” says Melody. Pay attention to the angle. It’s usually approximately 25 degrees though check your manual. For maximum accuracy, invest in a file guide. Slide the file across each tooth about 5 times in a forward motion. Count the times you sharpen each cutter to achieve a consistent finish.
  4. Sharpen the rakers Next, examine the gap between the teeth and the rakers (the bumps in-between). Use a depth gauge to determine whether any of the rakers are protruding. Slide a flat file across these to maintain the correct alignment.
