FourShow Nylon Replacement Blades for STIHL Polycut Trimmers — 25-Pack PA6 Nylon, 10.5 cm Flexible Durable

These are 25 durable PA6 (nylon) replacement plastic blades engineered to fit STIHL Polycut-style grass trimmers and restore cutting performance quickly and affordably.

If your STIHL trimmer has dulled or missing plastic blades, this FourShow pack supplies an economical way to get back to tidy edges and fast perimeter clearing. The blades are molded from PA6 nylon for flexibility and wear resistance; storing them briefly in warm water before first use helps them flex evenly and extend service life. Each blade measures 10.5 cm (4.1 in) and the set is sized to match popular Polycut-style heads and the OEM part number 41110071001.

Which STIHL models work with these replacement plastic blades?

These FourShow blades are designed to be compatible with a broad set of single-line Polycut heads and smaller STIHL trimmer models. They match the shape and dimensions expected by many Polycut-type cutting systems so installation is typically straightforward.

How do I install and prepare the FourShow nylon blades?

Installation follows the same basic steps as replacing other Polycut blades: remove the trimmer head cover, swap the spent blades for new ones, then secure the head. To reduce brittleness and improve initial flexibility, soak the nylon blades in warm water overnight before first use.

• Turn off trimmer and disconnect spark plug or battery before servicing.
• Remove the head cap, replace blades in the slots, then reassemble securely.
• Soak blades in warm water the night before using to increase durability.

What cutting performance and durability can I expect from nylon replacement blades?

PA6 nylon blades deliver a balance of flexibility and toughness for trimming grass, light weeds, and thin brush. They won’t outlast metal blades on heavy brush, but they reduce damage to hard surfaces and are safer around fences or flower beds.

• Good for lawn edges, soft vegetation, and weed control around obstacles.
• Flexible design reduces risk of shattering on impact with hard objects.
• Cost-effective for frequent blade changes and maintenance cycles.

Who is this for? These FourShow 25-piece nylon blade packs suit homeowners, landscapers, and rental shops that use STIHL Polycut-style trimmer heads and need a reliable, inexpensive source of replacement cutting blades. They’re especially useful when you want an easier, safer alternative to metal blades for light-duty trimming, or when you need multiple spares on hand for ongoing yard work. Remember to follow your trimmer manufacturer’s service and safety instructions when installing and using replacement blades.
