Cumbersome? Yes. Ornate? Certainly. Over the top? Absolutely. The Wenger 16999 Swiss Army Knife from around 1880 has roughly 100 functions—some necessary and some superfluous. From a built-in saw to a piano tuner, this knife can help with just about any pre-digital task. It even has a fully functioning .22 caliber pinfire revolver for those impromptu duel challenges. Regardless of its ridiculousness, the knife is a feat of craftsmanship and ingenuity for its time.
