Four Victorinox Orange Peeler Blades Together

After many moons, much mental anguish, suffering or turmoil, Crumby has at last acquired the smooth orange peeler, the initial iteration of that semi-important Victorinox tool.  Here it is depicted with the three later iterations.  There is, alas, a fourth iteration, that lacks the gut hook.  Seemingly, someone at Victorinox realized oranges lack guts, and was finally heard over the din of oranges have guts theorists.  Mercy!
