The Fairbairn-Sykes fighting knife is a stiletto-style dagger (a long, narrow-bladed dagger) developed by William Ewart Fairbairn and Eric Anthony Sykes during World War II with a foil-like handle and a keen, double-edged blade. Modeled on contemporary Shanghai street daggers, it was primarily intended for use by British troops, particularly Commando forces. Manufactured by the Wilkinson Sword Company in England, there were minor variations in pommel and grip, of interest now mainly to collectors. Because of its sleek lines and popular association with the OSS, Marine Raiders and other units..

In November 2005, WKC purchased the toolings of Wilkinson Sword Ltd. . for production of various ceremonial swords,including the F+S Knife.
