From Scorpion Knives. The Fairbairn-Sykes commando knife is a double-edged knife with a foil grip developed by William Ewart Fairbairn and Eric Anthony Sykes before World War II. It was made famous during the War when issued to British Commandos, including the SAS. Although the Fairbairn-Sykes knife is now of interest mainly to collectors, because of its sleek lines and its commando associations it still remains in production today.
