Abstract
A multicomponent monofilament cutting line includes a first component material and a second component material, the same or different in chemical structure from the first component material and extruded separately from the first component material. The second component material provides the cutting line with cutting edges and has increased wear resistance properties and increased abrasion resistance properties compared to those same properties of the first component material. The monofilament cutting line for a rotary trimmer for cutting vegetation preferably includes a first component material having a specific gravity of about 1.15 g/cc or less; and a second component material having a specific gravity greater than 1.15 g/cc. Notably, the multi-component, monofilament cutting line itself has increased wear resistance and increased abrasion resistance as compared to a single component monofilament cutting line employing one of either the first or second component materials.
