Last year I didn't have any poos to cut around. Bagging takes care of the clipping while cutting, but what about edging. Edging make a lot of dust in the air. I bought one of the manual edgers, but it doesn't make the grade. Will the manual work a lot better if I sharpen the tines? Please let me in on some methods that work.. Cusomer is very picky about the pool. I do understand why.
