The Dagger Commandos Doubted... Then Became the Face of Special Forces

In November 1940, two former Shanghai policemen walked into a private sword company with nothing but a sketch and years of street combat experience — and designed a knife the British military never officially standardized for the next nine years. This documentary traces the Fairbairn-Sykes Fighting Knife from its origins in the violent back alleys of the Shanghai Municipal Police, through the off-the-books meeting with Wilkinson Sword that created it, to the Commandos, Airborne Forces, SAS, and OSS operatives who carried it into occupied Europe without a single formal government specification behind it. We break down why its blade geometry, S-shaped grip, and hand-ground first pattern were built purely for silent, close-quarters killing — and how a weapon born outside the official procurement system became the single most copied insignia in special forces history, from the Royal Marines to the U.S. Army Rangers.
