Behold the Mother of All Swiss Army Knives, a multi-tool created by John S. Holler in Germany around 1880. The knife actually predates the Swiss Army Knife, which started production about a decade later in 1890.
The knife has 100 functions, including every types of blades imaginable. You can even use this tool to tune a piano, as it has a piano tuner built in. Hungry? It's got a butter knife so you can butter your toast. But that's not all. It has a fully functioning .22 caliber five-shot pinfire revolver.
