We recently visited the Swiss Army Knife factory and saw their collection of vintage knives. We have also seen the ridiculousness that is the Wenger 16999. This "multi-tool' though tops them all. Created by John S. Holler in Germany around 1880, the knife has 100 functions including shears, an auger, saws, a lancet, cigar cutter, pens, straight razor and piano tuner. And yes, that is a fully functioning .22 caliber five-shot pinfire revolver you see there. (via)
