multibladed pocketknife that evolved from knives issued to Swiss soldiers beginning in 1886. Although the knives were originally produced in Germany, Swiss cutler Karl Elsener began making soldiers' knives in 1891, equipping them with a blade, reamer, screwdriver, and can opener. The officer's knife, with a second blade and corkscrew, appeared in 1897. The knives continue to be supplied by two Swiss manufacturers, Victorinox (Elsener's firm) and Wenger, and both the military and civilian models bear the Swiss federal cross logo.

There are hundreds of models of Swiss Army knives, which among their many tools may incorporate attachments such as a saw, pliers, scissors, compass, light, tweezers, whistle, fish scaler, file, pen, wirecutter, or altimeter. Models are especially designed for specific users—campers, hunters, computer repairers, golfers, and handymen. The name has become a metaphor for a compact, ingeniously designed tool with multiple uses.
