I just received a new Victorinox Hercules, and the standard size Phillips screwdriver doesn't snap back to it's folded position. It does appear to have a strong spring and it snaps open forcefully, but there isn't enough return force to stow it, and I have to manually close it after the spring tension is released. The long smaller Phillips screwdriver seems to have a much stronger spring, and it snaps and returns to the folded position. A few months ago I purchased a new Victorinox Climber that has a cap lifter that will not snap back either, but I haven't sent it in for repair yet. Should the screwdriver snap back into place, or is it behaving normally? I hate to send this great knife in for repairs if it's not necessary. I did oil the screwdriver as well, and it didn't help any. Any advice is appreciated.
