Stihl straight shaft trimmers take a variety of attachments, but the only one used regularly around here by the yard guys is thie pole trimmer for trees. Interchangeable heads are a selling point for straight-shaft trimmers, but I don't think they offer much real utility. Yard pros do edging with their string trimmers or with gas edgers. I use an electric B & D Edgehog; has lasted four years and I run through about a blade a year.
