Hello! I used to own a Skeletool years ago. It was the 830948 model. After a while it started getting little rust spots on it. I don't work in or near water, I never wet it or anything. Anyone have this same issue? I plan on ordering another one today or tomorrow as I lost mine a few years ago and I am finally getting around to getting a new one. Should I get that same one or spring for the 830950?
