How to Sharpen a Hedge Trimmer

When it comes to maintaining your hedge trimmer, one of the most important tasks is sharpening the blades. A dull blade can not only make trimming less effective, but it can also put a strain on the motor and potentially cause damage.

Fortunately, with a little practice and the right tools, sharpening your hedge trimmer’s blades can be done at home. If you’re not comfortable sharpening the blades yourself, you can always take them to a professional or purchase pre-sharpened replacement blades.

In this blog post, we’ll walk you through the steps of sharpening your hedge trimmer’s blades at home. So, stay tuned, and let’s get started!

Sharpening the Hedge Trimmer | All There Is to It

Gather the Tools

First, gather the necessary tools for sharpening your hedge trimmer blades. You’ll need:

  • A flat file
  • A round file (the diameter should match the size of the blade)
  • A pair of gloves
  • And some lubricating oil.

Prepare the Workspace

Next, prepare your workspace by clearing it of any debris or clutter and laying down a tarp or newspaper to catch metal shavings. Put on your gloves to protect your hands.


Before sharpening, lubricate the blades with a light coating of oil. This will help prevent the blades from overheating during sharpening.

Stare Sharpening

Now, it’s time to begin sharpening the blades. Using the flat file, carefully file the blades in a back-and-forth motion, making sure to keep the blade at a consistent angle.

It’s important to file in one direction only, as filing back and forth can cause damage to the blade. Focus on any nicks or dull spots first before going over the entire length of the blade.

Once you’ve finished filing with the flat file, switch to the round file and repeat the same sharpening process. Make sure to remove any metal shavings that may have accumulated during sharpening before moving on to the next blade.

Continue sharpening each individual blade until they are all nice and sharp. You can test the sharpness by lightly running your finger along the blades.

Now Clean it Off

Lastly, clean off any remaining metal shavings and lubricate the blades with oil once again before reassembling your hedge trimmer and getting back to work.
