An improved filament for use in the cutting of weeds and vegetation, wherein the filament is attached at one end to a hub for imparting rotary motion to the filament. The centrifugal force extends the filament radially outwardly from the hub, with the energy of rotation being utilized to sever or cut the vegetation. The filament has a generally centrally disposed axis with an irregular or variant cross-section which fluctuates along the axial length of the filament. The variant cross-section with its fluctuations in cross-sectional area reduce the end or terminal fibrillation of the filament.
