I currently have a push walk behind gas edger used once per year on accounts and use my Stihl FS90 R trimmer the rest of the season. This is killing my wrists the way I have to hold my trimmer to cut the edge. Thinking of getting an edger, but now I have seen website on Edgit. On the Edgit can you still trim with it or does it make your trimmer into an edger only? Which would you guys suggest?
