Whether you want to know how to sharpen hedge trimmers with a file or what is the best way to sharpen hedge trimmers we’ve got you covered.

Tools to Sharpen Hedge Trimmers
Before you start
- Flat File: For manual sharpening.
- Mill File: A finer file for more precise sharpening.

How to Sharpen Hedge Trimmers
1. Prepare Your Area
Set up a clean, flat surface with good light. Unplug your trimmers if electric or battery operated to avoid accidental start.
2. Clean the Blades
Use a rag and cleaning solution to remove dirt, sap and debris from the blades. This step is important to ensure even sharpening.
3. Check the Blades
Look for damage or excessive wear. If there are deep nicks or bends consider consulting a professional or replacing the blades.
4. Clamp the Trimmers
Use a clamp or vice to hold the hedge trimmers in place. This will keep everything stable while sharpening and prevent accidents.
5. Sharpening Hedge Trimmers with a File
1. Find the Cutting Edge
Locate the bevelled edge of the blade—this is the side that cuts and needs sharpening.
2. Use a Flat File
- Hold the file at the same angle as the bevelled edge (usually around 20-30 degrees).
- Push the file away from you along the blade’s edge in smooth strokes.
- Don’t go back and forth; this can damage the blade.
- Repeat until sharp, usually 5-10 strokes per section.
3. Repeat on the Other Blade
For dual blade hedge trimmers repeat the process on the other blade. Both blades should be sharpened evenly for best results.
6. Use a Sharpening Stone for Finishing
After filing use a sharpening stone to smooth and polish the edges:
- Wet the stone with water or oil.
- Run the stone along the bevelled edge in a circular motion.
- Wipe the blades clean after.
7. Check the Sharpness
Test the sharpness by running your finger (perpendicular to the edge) along the blade. It should feel sharp but not rough.
8. Reassemble and Test
If you took the trimmers apart, reassemble according to the manufacturer’s instructions. Test on a small section of hedge to make sure it cuts smoothly.
Hedge Trimmer Blade Maintenance
- Clean Regularly: Clean your blades after every use to prevent rust and sap build up.
- Lubricate: Apply a light coat of oil to the blades to reduce friction and rust.
- Store: Store your hedge trimmers in a dry place to prevent moisture damage.
- Sharpen Often: Sharpen your blades every 25-30 hours of use or when you notice a decrease in cutting performance.
