well everyone, thanks so much for your responses, don't know unless we ask. anyway, about rotors, thought I could do them like scissors. so I guess it's better to just throw them away. and as for sharpening the scissors, well I do have the cheap kind. so its best to get the high-quality ones, well in anything that is what we should do. and as for Joannes, I will have to check that out and the one close to me. again thanks for the info.
