Stihl 250mm (10") Tri-Bladed Steel Brush Knife
Destroy Dense Brush and Thorny Scrub with Professional Ease
When your standard trimmer line meets its match, the Stihl 4112 713 4100 Brush Knife takes over. This professional-grade, 3-bladed steel attachment is specifically engineered to thin out or remove tough, woody vegetation, matted dry grass, and invasive thorny hedges.
Crafted from high-quality, durable steel, this 250mm (approx. 10") blade features a reversible design, allowing you to flip the blade in the field to maintain a sharp edge for longer periods of uninterrupted work. It is the go-to tool for forest maintenance, large-property clearing, and professional landscaping.
Key Performance Benefits:
- Heavy-Duty Clearing: Optimized for cutting through reeds, thick brush, and tangled weeds where a string head would fail.
- Long-Lasting Performance: High-strength steel construction resists wear; reversible blade doubles the service life between sharpenings.
- Genuine Stihl Quality: Ensures perfect balance and reduces vibration to protect your brushcutter's gearbox and reduce operator fatigue.
- Resharpenable Edge: Easily maintain the cutting edge with a standard flat file.

Frequently Asked Questions
Frequently Asked Questions
+ Which Stihl models are compatible with this blade?
The 250mm Brush Knife (4112 713 4100) fits a wide range of Stihl straight-shaft brushcutters, including the FS 80, FS 85, FS 89, FS 91, FS 111, FS 131, FS 240, and the FSA 130/135 battery models. It also works with KM 91/111/131 KombiSystems with the brushcutter attachment.
+ Can this blade be used on loop-handle trimmers?
For safety reasons, no. Stihl recommends using metal blades only on brushcutters equipped with bicycle (bike) handles, a double shoulder harness, and the correct limit stop guard to prevent kickback injuries.
+ How do I sharpen the Brush Knife?
The 3-tooth brush knife can be easily resharpened using a standard flat file. Regular maintenance keeps the blade aggressive and prevents the engine from overworking.
+ Can I cut trees or saplings with this blade?
This blade is designed for thick green vegetation, brambles, and light scrub. For cutting woody saplings or tree trunks over 1/2 inch in diameter, we recommend using a Stihl Chisel Tooth or Scratcher Tooth circular saw blade.
