How to Sharpen Hedgetrimmer Blades

Keeping your hedge trimmer blades sharp is essential for clean, efficient cutting and maximising the lifespan of your tool. Dull blades will tear and snag at branches, leaving ragged edges and requiring more effort to push through. Regular sharpening ensures a smooth, clean cut and reduces wear and tear on the motor.

There are two main methods for sharpening hedge trimmer blades: using a flat file and using a whetstone. Both methods require care and attention to detail, but with a little practice, you can keep your blades sharp and your hedges looking their best.

• Gloves
• Safety Glasses
• Flat File
• Whetstone (optional, for finishing)
• Vice or Clamp
• Wire Brush

Before sharpening your hedge trimmer blades, always unplug the trimmer or remove the battery. Wear gloves and safety glasses to protect yourself from cuts and stray metal shavings. Secure the blades in a vice or clamp to prevent them from moving while you work.

1. Select a flat file with a width that roughly matches the width of the teeth on your hedge trimmer blades
2. Identify the bevel on the cutting edge of each tooth. This is the angled edge that does the actual cutting
3. Holding the file at the same angle as the bevel, run the file along the edge in one smooth, even motion away from you. Apply light to moderate pressure
4. Repeat for each tooth on both sides of the blade. Be sure to maintain a consistent angle throughout the process
5. Once all the teeth are sharpened, use a wire brush to remove any metal filings

1. Use a whetstone with a fine grit for finishing the sharpened edge
2. Lightly moisten the whetstone with water
3. Hold the blade at a shallow angle (around 15 degrees) and run it back and forth along the whetstone, following the bevel of the cutting edge
4. Repeat for each tooth on both sides of the blade

• Don't remove too much material from the blades. Aim for just a few passes with the file or whetstone
• Sharpen both sides of the blade evenly
• If you're unsure about sharpening your blades yourself, you can take them to a professional sharpening service

• Clean your hedge trimmer blades after each use with a damp cloth to remove sap and debris
• Store your hedge trimmer in a dry place to prevent rust
• With proper care and maintenance, your hedge trimmer blades will stay sharp for many seasons to come
