Abstract
A grass trimmer line includes a first line body having a first free end and a first non-free end and a second line body having a second free end and a second non-free end. A length of the second line body is substantially equal to a length of the first line body. The first line body has a first feature, the second line body has a second feature corresponding to the first feature, and the second feature is different from the first feature. A connecting portion is configured to connect the first non-free end of the first line body and the second non-free end of the second line body so that the first line body and the second line body are connected into the complete grass trimmer line.
