A little while back, I was watching Jay Leno one night. On that particular night, he had a large contingent of military folks in his audience, from all services. May've been a Memorial Day show or something. At any rate, during one segment of the show, he invited one member of each service to the stage to have a contest. The 'contest' was to see how fast each could open a tin can using a Swiss Army Knife (no idea what brand they provided to the participants). What really disturbed me, was how much difficulty most/all of the contestants had in opening the can. One or two participants even cut themselves after using the 'tool' to punch/stab/hack their way partly into the lid, then using their hands to rip/peel the lid open (ouch!).
I couldn't help but wonder if the 'Swiss Army Knife' provided to the contestants was the real deal (Vic or Wenger), or if they were given some sort of cheap knock-off with a truly crappy can opener. I had to test it for myself, so I grabbed my Vic Mechanic and went to the kitchen to open up a can of peaches. No troubles whatsoever, worked like a dream. Took maybe 30 seconds, tops. It was actually the first time I'd even tried to use the can opener on it. It seemed intuitive as to how to make it work, so I really do wonder if the deck was stacked against the contestants with a junk tool.
Edited to add:
Just did a Google search. Found a site that mentioned the same show. Turns out it was the Thanksgiving '09 show, and they were opening cans of cranberry sauce. Still looking to see if I can find a video of it...
