hi, is there any user maint tricks to removing the assembly etc. I have an old early model skeletool cx with the partially serrated blade and its bit holder latch is very worn, bits can come out if you flick it about. it is built inside the side plate and looks like held in with 2 pins, but the top of the catch is partially spring loaded, no way to unpin it? If i send it in for warranty its an older discontinued model, so a skeletool cx would now come with the straight blade. Any ideas?
