Method 1: How to Sharpen Hedge Trimmer Blade Using a Flat File
The file is a simple and cheap tool used for sharpening metal blades. You can learn how to sharpen hedge trimmer blades using a flat file in the following simple steps.
Gear up and wear your safety equipment to avoid any injury.
Clean your blades with a wet cloth to get rid of any dirt and debris.
Take your file and start running it down each cutting edge of the blade. Maintaining the angle of the file the same as the cutting edge of the blade is very important.
Ensure that you run the file down only in one direction, similar to the cutting edge, and not back and forth.
Sharpen all sides and edges of the blade with the file and make sure you don’t file too much, as it may weaken the blade.
Once you are done with the filing process, take a clean wet cloth and wipe away dust from filing on the blade.
Now use the whetstone to smooth the blade’s roughened surface and get rid of any burrs after filing. Turn over the blade and moisten it a little bit. Swipe down the whetstone in the same direction of the edges and tip and smoothen the blade as you go.
To test how sharp your blade is, you can test it with a sheet of paper. A well-sharpened blade should easily and cleanly cut the paper.
You can lightly coat the surface of the blades with some linseed oil or an anti-corrosion spray. It will preserve the blade, ensure a longer lifespan, and keep it from rusting.
Method 2: How to Sharpen Hedge Trimmer Blade Using a Power Grinder or Dremel Tool
If you own a power grinder and know how to use it, this method will work great for you. Using a power grinder is a much quicker and more effective way to sharpen your hedge trimmer blades.

On the contrary, the Dremel tool is a much safer, more efficient, and easy-to-use alternative to a power grinder. Here’s the guide on how to sharpen hedge trimmer blades using these tools.
Note: Use the same steps and follow instructions from the manual of your Dremel tool. Its usage is quite similar to a power grinder, and it is only recommended for its special attachments to sharpen gardening tools.
Gear up! Wear your safety goggles and gloves.
Now clamp the blade on a bench, so it doesn’t move while you sharpen it.
Run down the power grinder at the angle of the cutting edge and move unidirectionally towards the edge. Turn over the blade and repeat it on the other side too.
To finish off, repeat this process for all the tooths and then wipe off the blade with a damp cloth.
