I am guna pick up the stick edging attach for my Shiny multi-tool today and have a couple of questions about stick edging. #1 Is there any tricks to using one and getting a nice clean edge #2 Do you use the stick edger once to cut in an edge and from then on do you maintain it with a trimmer or do you continue to use the stick edger? #3 How long do the blades last ? say if I had 300 ft to edge, how would the blade look after that? Do yous think I should pick up a contractors blade pack with 50 blades in it ? #4 Do you think Stick edgers are Superior to a trimmer?
