Identify a Fairbairn-Sykes style knife. The Fairbairn-Sykes fighting knife is a double-edged knife. Look for a thin blade with the a small, round foil guard over the handle. The grip is rounded and thickest in the centre with a slender neck three-quarters of the way toward the bottom.
Check the blade length. A Fairbairn-Sykes knife came in two different lengths. The first design had a 6 1/2-inch blade, while second and third design knives had a 7-inch blade.
