    Patent number: 4100636
    Abstract: A grass edge trimmer includes a blade having at least one longitudinal cutting edge mounted on a handle by means of a pair of clamping portions. The clamping portions are located on opposite sides of the blade and engage the same along but spaced from said cutting edge so as to stiffen the blade. One of the clamping portions is removable from the handle and permits a worn cutting edge of the blade to be interchanged for a fresh cutting edge.
