A disk-shaped filament holder and dispenser for a filament trimmer; the disk has a central attachment for a power drive and a plurality of circumferentially spaced holes through which a filament having one end secured to the disk is threaded; the free end of the filament during operation swings radially from the disk as the cutting filament, or filament trimmer; abrasive contour of the holes insures that the free end of the filament will fail first at the last hole through which threaded rather than at some portion of the free length; on such failure, centrifugal force pulls the stub end free from the hole at which failure occurred and swings it out radially from the disk at the next prior hole through which threaded, as a fresh cuttinglength of filament.
