I used to struggle to remove corks with the SAK until I realized that I was doing it the hard way! You aren't supposed to screw it in and pull like an idiot until your face turns red and you damage your shoulder. The trick is to screw it down all the way, then use the SAK as a lever (it is hinged you know) and pry the cork out as far as the knife/corkscrew/hinge allows - THEN you pull the remaining distance. I haven't had any trouble since I learned that technique.
