I have no interest in the White House myself. I'm much more interested in the Smithsonian Institute. Anyway, because I'm curious, I measured the longest blade on my Victorinox Executive. I measured it the "dumb" way, sliding the ruler down the side of the blade until it stopped against the handle of the knife. It was still just a wee bit over two inches. <br><br>I did it that way because since the regs don't spell out how blades should be measured, some overzealous guards get to add to their own collections by measuring blades in just that fashion, rather than measuring the length of the actual cutting edge itself.
