Fairbairn–Sykes fighting knife

The Fairbairn–Sykes fighting knife is a double-edged dagger that has become iconic due to its association with British commandos and special forces during World War II. Designed by William E. Fairbairn and Eric A. Sykes, the knife was intended for close combat and inspired by similar daggers used in Shanghai in the 1930s. Its design is noted for being simplistic yet highly effective, featuring a slender blade that allows for quick, precise strikes. The handle is usually textured for a firm grip, ensuring that it remains secure in the user's hand during intense combat situations. The Fairbairn–Sykes knife has since influenced numerous modern combat knives and remains a symbol of elite military forces.
