Short answer
Hedge trimmer blades differ in sides (single or double), tooth spacing (which sets the thickness of stems they can cut) and length. Wider tooth spacing cuts thicker stems; closer spacing gives a finer finish. Choose based on your hedge type and size.
| Feature | Options | What it affects |
|---|---|---|
| Cutting sides | Single-sided or double-sided | Control, speed, and weight |
| Tooth spacing | Narrow to wide gaps | Maximum stem thickness |
| Blade length | Around 45cm to 75cm and more | Hedge size, reach, weight |
| Blade shape | Straight, angled or curved | Finish and shape of cut |
| Tip | Rounded or open | Safety and detail work |
How to choose
- Small formal hedges: shorter, fine-toothed blades.
- Large mixed hedges: longer blades with wider tooth gaps.
- Thick, woody growth: look for a capacity that suits the job: see thick-branch trimmers.
