OK, I know this is an old thread but I'm looking into the screw splitters. My main concern is wear life of the screw. Anybody here run one of these long enough to wear one out? The videos on You Tube I've watched scare the crap out of me because those guys wear long sleeves and worse yet, gloves. If I get one I'm going be as naked as I can get and that includes jewelry. That way it will be cheaper for the undertaker to dress me.
