Abstract
A flexible noise attenuating cutting line for use in rotary vegetation trimmers formed by extruding a pair of molten monofilament strands in proximate disposition through a rotating die so as to form a line comprised of two monofilament polymer strands bonded together in a twisted disposition about a central longitudinal axis so as to define a pair of substantially V-shaped opposed troughs extending helically along and about the line.
