I just had the idea of using a spent circular saw blade on my edger while doing over-growth. We all hate edging over-growth, what with the nasty sod snakes and the general mess it makes and the time it takes. So I got to wondering if a smaller toothed saw blade on a stick edger might zip right through the dirt better? Anyone tried it? Either way, I'm buying the first garage sale 4-5hp Brigs unit I come across for doing over-growth.
