I have this old, beat up Rover hanging around (like a Rally, but with a flathead combo tool rather than Phillips). It's a "Pepcid" pharmaceutical promotional piece, but for some reason, the white Cellidor scales have become deformed in a way I've never seen happen with any Victorinox knife. Anyway, today I popped the scales off of it (I've never before done this to a knife), and I have been admiring the way the 58 mm tools and backsprings go together. It's really a brilliant design. The back springs are really only attached at the end opposite the tool joint, and the springs are curved so that the fulcrum ends up being the contact point between the backsprings on opposite sides. How ingenious! I guess the Money Clip uses this design, as well.
