FourShow 100Pcs PA6 Plastic Blades for Gtech grass trimmers
Product description
If your Gtech grass trimmer blades are looking a bit worse for wear, it can feel like a small problem that quietly gets annoying. These FourShow 100Pcs PA6 plastic blades are built for replacement, with a stated 67 mm length and a bulk pack that’s aimed at keeping your strimmer running without constant re-ordering.
On paper, this is a straightforward “swap in new blades” type of purchase. The key is that they’re specified as compatible with a range of Gtech models listed by the manufacturer, and they’re supplied as a large quantity of spares—handy if you prefer to keep replacements ready rather than waiting until yours fully wear out.
Key takeaways
The headline here is simple: 100 replacement blades made from PA6 plastic, cut to 67 mm length, and intended for certain Gtech grass trimmers. It suits people who want a practical way to restore cutting performance when blades dull, rather than trying to push on with worn parts.

The part that may not suit everyone is the material choice. Plastic blades can work well in the right setup, but they’re not the same approach as metal blades if you regularly hit tougher growth or rocky edges. Also, the listing specifically advises soaking the blades in water before use—worth following, because it’s not the sort of step you’d do if you were expecting a “fit and forget” experience.
What you’ll notice in day-to-day use
When grass trimming is going well, you tend not to think about the blade at all. But when blades start losing effectiveness, you’ll notice the work takes longer and the cut looks less consistent. A fresh set can make the strimmer feel like it’s back to its usual pace.
These blades are described as “for high performance” and “to keep these blades in good condition”. That ties into the practical instruction to soak them in water before using. For a micro example: before starting your next tidy-up, you could soak the replacement blades, then fit them so your first pass through the edging is cleaner, rather than fighting dull cutting action.



What matters most for compatibility
Compatibility matters more than most people expect, especially with strimmer blades where fit and intended use are model-specific. This pack is listed as compatible with Gtech trimmers including ST01, ST02, ST04, ST05, ST20, and models noted as GT3.0, GT4.0, and GT50.
It’s also worth noting the blades are described as replacements for the original blades. That’s a good sign if you simply want like-for-like replacement rather than adapting parts.
The essentials (specs at a glance)

- Type: Plastic blades (PA6)
- Quantity: 100 replacement blades
- Length: 67 mm
- Compatibility (as listed): Gtech ST01, ST02, ST04, ST05, ST20, GT3.0, GT4.0, GT50
Where it shines (and where it doesn’t)
It’s a solid pick if you’re doing regular garden edging and you’d rather maintain performance by swapping blades when they start to underperform. The 100-pack makes sense if you want a long-term supply, or you simply hate the idea of delaying maintenance until the last set is fully gone.
It may not be a great match if you expect the blades to feel “premium tough” in the way metal options often do. If your trimming routine involves tougher, stubborn growth, rough surfaces, or frequent accidental contact with harder materials, plastic blades can be more limiting. And if you don’t want to follow the soaking instruction before use, you may find the process a little less convenient than other replacement options.



How to get the most from them
The listing explicitly advises that you should ensure the blades are soaked in water before using. That’s the sort of detail that can be easy to skip, but it’s directly tied to the “better performance” claim.
Also, since this is a replacement pack, you’ll get the best results by treating it like maintenance rather than a one-off “try it later” purchase. If your current blades feel less effective, replacing them promptly can help you keep cutting consistent rather than forcing extra passes.
Is it worth it?

It’s worth buying these FourShow 100Pcs PA6 plastic blades if you own a compatible Gtech model from the list provided, you want replacement blades with a stated 67 mm length, and you prefer stocking up on spares. The large quantity can be good value when you’re planning for routine maintenance.
You may want to skip it if you’re specifically looking for a more robust cutting approach, or if you don’t want to take the extra step of soaking the blades in water before use. Also, double-check compatibility for your exact trimmer model before committing—these replacements are meant to match listed Gtech models, not every strimmer out there.
