A holder for a monofilament line used in a vegetation cutter, such as a grass trimmer or lawnmower, is divided into four quadrants and has a series of clips between each quadrant through which the monofilament line is woven for being held on the holder. The periphery of each quadrant is an arc slightly off center from the radial center of the holder, thereby creating a protrusion on the direction of rotation side of the clip area. This protrusion maintains hard objects, such as stones, away from the holder periphery on the other side of the clip area, thereby preventing the hard object from shearing off the monofilament line. In order to reduce the weight of the holder, recesses are formed on both sides thereof and the ground facing side recesses are angled to avoid the entrapment of grass in the holder. When the holder is used with an impeller type hovering lawnmower, the diameter thereof is made substantially the same as the diameter of the impeller to act as a shield for the impeller against abrasion.
