Whether you’re a weekend gardener or a professional landscaper, one tool stands out when you need to tackle thick weeds, brambles, or overgrown edges: the grass strimmer with blades. While traditional string trimmers work well for light trimming, bladed strimmers are in a league of their own when it comes to power and precision.
In this comprehensive guide, we’ll explore everything you need to know about bladed grass strimmers—from what they are and how they work, to the types of blades available, how to use them safely, and how to choose the best one for your needs.
What is a Grass Strimmer with Blades?
A grass strimmer with blades is a versatile gardening power tool designed to cut through dense vegetation using sharp metal or plastic blades instead of nylon string. It’s an upgraded alternative to the standard string trimmer, especially useful for:
- Thick grass and weeds
- Tough brush and undergrowth
- Woody stems or brambles
- Edging along fences and walls
These tools are often referred to as brush cutters, although some grass trimmers have interchangeable heads that allow you to swap between string and blades.
Why Choose a Bladed Strimmer Over a String Trimmer?
Here’s why more gardeners and landscapers are opting for blade-equipped models:
✅ More Cutting Power
Metal blades slice through heavy growth that would wrap around or break nylon string. They’re ideal for untamed areas.
✅ Longer Lasting Performance
Blades don’t wear down as quickly as string. You don’t need to stop mid-job to reload.
✅ Versatile Applications
While string is great for delicate lawns, blades can tackle brush, vines, and even small saplings.
✅ Efficient in Large or Wild Areas
If you maintain larger plots, orchards, or overgrown areas, a bladed trimmer saves you both time and energy.
Types of Blades for Grass Strimmers
Not all blades are created equal. Here’s a look at the main types:
1. Metal Blades
- Material: Steel or alloy
- Use: Heavy-duty tasks like cutting thick grass, shrubs, or saplings
- Variants:
- 3-tooth blade: Good for grass and light brush
- 8-tooth or 40-tooth saw blades: Suitable for woody shrubs and stems
2. Plastic Blades
- Material: Hardened plastic
- Use: Light to medium trimming—denser than string but less risky than metal
- Pros: Safer, easier to replace, great for casual gardeners
3. Tri-Arc Blades
- Triangular or curved, these blades provide better balance and maneuverability.
4. Multi-Tooth Blades
- Resemble circular saws and are used for extreme brush clearing.
🛠️ Pro Tip: Always match your blade to your job. Using a metal saw blade for light grass is overkill and can be dangerous.

🔹 Can I convert my string trimmer to a bladed one?
Yes, but only if your model supports it. Check your manual for blade compatibility. Never modify a unit without manufacturer guidance.

Plastic blades—yes. Metal blades—use with caution. They’re better suited for rugged trimming, not delicate lawn edges.
