.120 inch Blister-1 Metal Trimmer Line

Engineered for extreme conditions, the Metal Trimmer Line combines revolutionary hybrid construction with uncompromising performance. Featuring a precision-wound carbon steel core encapsulated in impact-modified nylon, this dual-material marvel delivers unprecedented durability in both round and square profiles. The textured nylon exterior resists abrasion while strategically exposed steel micro-edges tackle vegetation that destroys conventional lines. The Metal Trimmer Line refuses to snap when striking rocks, concrete, or buried debris – boasting 300% greater fracture resistance than premium nylon competitors in ASTM D638 stress testing.

Unmatched Cutting Authority
The Metal Trimmer Line operates as nature’s chainsaw at 10,000 RPM. Its rigid steel core eliminates line deflection, transforming centrifugal force into surgical cutting power. While standard lines whip against obstructions, the Metal Trimmer Line pulverizes ½" diameter woody stems, bamboo shoots, and invasive vines like kudzu with decisive shearing action. Thermal imaging confirms a 62°F reduction in cutting-tip temperatures versus standard nylon when processing silica-rich vegetation like sawgrass or Russian thistle. This thermal efficiency translates to 40% faster clearance of drainage ditches, fence lines, and neglected easements where other lines melt or fray.

Intelligent Flexibility Engineering
Defying expectations of rigid metal systems, the Metal Trimmer Line features proprietary Flex-Steel™ technology. The helix-wound core distributes stress across 17 micro-segments, allowing 22° of directional compliance during complex cutting maneuvers. This preserves crucial multi-angle capability while eliminating the "bounce effect" that plagues solid-core alternatives. Advanced harmonic balancing reduces vibration amplitudes by 47% (ISO 5349-1 certified), preventing white-finger syndrome during extended operation. The Metal Trimmer Line protects both operator and equipment – lowering trimmer gearbox wear by 35% while maintaining smooth control in unpredictable terrain.
