A Swiss Army knife is a multi-tooled pocketknife known for its versatility and compact design.

While originally designed for the Swiss Army, these knives have become famous worldwide as consumer products. They serve as portable toolkits, combining several different implements into a single handle. This design allows a user to carry many solutions for various tasks in one small package. Because they are so useful, they have become a major icon of Swiss culture.

The functionality of the knife relies on a clever pivot point mechanism.

This mechanism allows different tools to fold neatly into the handle. When a tool is needed, it is swung out from the handle's body. Once the task is complete, the tool is folded back into its designated slot. This keeps the sharp edges protected and prevents them from poking the user. The entire assembly is held together by metal pins called rivets. These rivets are made by cutting and pointing bars of solid brass.

Swiss Army knives feature a wide variety of tools categorized by their location in the handle. The main layer typically contains the most essential implements. This often includes a large blade, a small blade, and a nail file. Other common tools in this layer are scissors, a wood saw, and a magnifying glass. Some models also include specialized items like a Phillips screwdriver, a can opener, or a bottle opener. The back layer of the knife often holds different tools. These might include a corkscrew, a reamer, or even a small toothpick and tweezers.

The history of these tools began with a specific need from the Swiss military. In the late 1880s, the army required a knife for opening canned food. Soldiers also needed a screwdriver to maintain their Schmidt–Rubin service rifles. In January 1891, the official Modell 1890 was designated. Because no Swiss company had enough capacity, the first 15,000 knives were made by Wester & Co. in Germany.

Karl Elsener, who owned a surgical equipment business, began making them in Switzerland in 1891. He eventually developed a patented "Swiss officer's and sports knife" in 1897. This improved design featured tools on both sides of the handle using a special spring mechanism.

Over the decades, the industry saw the rise of two major Swiss companies: Victorinox and Wenger. In 1908, the Swiss government split its contracts between these two makers. Karl Elsener's company eventually became Victorinox, using his mother's name, Victoria, for the brand. Wenger also produced similar high-quality knives for many years. In 2005, Victorinox acquired Wenger, becoming the sole supplier to the Swiss military.

While the Wenger brand was eventually retired in 2013, some of its products continue under the Victorinox name. This consolidation helped the companies navigate a decline in sales caused by competition and airline travel restrictions.

Modern manufacturing uses advanced materials to ensure these knives are both strong and light. The cutting blades are made from a martensitic stainless steel alloy called X55CrMo14. This metal contains 15% chromium, which helps it resist corrosion. The blades undergo a hardening process at 1040 °C and an annealing process at 160 °C. This results in an average hardness of 56 HRC. To keep the knives light, the separating layers between tools have been made of aluminum alloy since 1951. Previously, these layers were made of nickel-silver.

Some Swiss Army knives are built to be extreme examples of multifunctionality. In 2006, Wenger produced "The Giant," which contained 87 tools and 141 different functions. This knife was recognized by Guinness World Records as the world's most multifunctional penknife.

Another massive knife made in 1991 featured 314 blades and weighed 1.3 kilograms. Modern technology has even entered the collection. Some high-tech models now include LED lights, USB flash drives with biometric fingerprint technology, and laser pointers.
