I noticed the same.
I wonder when the pen knife changed from being a simple folding blade to the multitooled wonder we have today?
Also does it say something about generals and the military that the two missing/broken tools are the scissors and tooth pick?
Edit: Apparently they have a longer history than I would have thought
"The Swiss Army Knife was not the first multi-use pocket knife. In 1851 in "Moby Dick" (chapter 107), Melville references the "Sheffield contrivances, assuming the exterior - though a little swelled - of a common pocket knife; but containing, not only blades of various sizes, but also screw-drivers, cork-screws, tweezers, awls, pens, rulers, nail-filers, countersinkers.""
