The F–S fighting knife was designed exclusively for surprise attack and fighting, with a slender blade that can easily pe*****te a ribcage. The vase handle grants precise grip, and the blade's design is especially suited to its use as a fighting knife. Fairbairn's rationale is in his book Get Tough! (1942).
In close-quarters fighting there is no more deadly weapon than the knife. In choosing a knife there are two important factors to bear in mind: balance and keenness. The hilt should fit easily in your hand, and the blade should not be so heavy that it tends to drag the hilt from your fingers in a loose grip. It is essential that the blade have a sharp stabbing point and good cutting edges, because an artery torn through (as against a clean cut) tends to contract and stop the bleeding. If a main artery is cleanly severed, the wounded man will quickly lose consciousness and die.[5]
The Fairbairn-Sykes was produced in several patterns. The Shanghai knife on which it was based was only about 5.5 in (14 cm) long in the blade. First pattern knives have a 6.5 in (17 cm) blade with a flat area, or ricasso, at the top of the blade which was not present on the original design and the presence of which has not been explained by the manufacturers, under the S-shaped crossguard. Second-pattern knives have a slightly longer blade (just less than 7 in (18 cm)), 2 in (5.1 cm)-wide oval crossguard, knurled pattern grip, and rounded ball, and may be stamped "ENGLAND" (a U.S. legal requirement when importing the surplus knives into the USA after WWII, as they had to show the country of origin) on the handle side of the cross guard. Some may also be stamped with a "Broad Arrow" /|\ British issue mark and a number (e.g., 21) on the opposite handle side of the cross guard. Third-pattern knives also have a similarly-sized seven-inch blade, but the handle was redesigned to be a ringed grip. This ringed grip is reputed to have distressed one of the original designers as it unbalanced the weapon and made harder to hold when wet, but it was used by the manufacturers as it was simple to produce and could be cast from a cheaper and more plentiful alloy instead of using up scarce quantities of brass stock which were of course required for ammunition casings and other such vital applications. Third-pattern knives may be stamped "WILLIAM RODGERS SHEFFIELD ENGLAND", "BROAD ARROW", or simply "ENGLAND". William Rodgers, as part of the Egginton Group, now also produce an all-black "sterile" version of the knife, which is devoid of any markings showing maker for NATO use.
The length of the blade was chosen to give several inches of blade to pe*****te the body after passing through the 3 in (7.6 cm) of the thickest clothing that was anticipated to be worn in the war, namely that of Soviet greatcoats. Later production runs of the F–S fighting knife have a blade length that is about 7.5 in (19 cm).
In all cases the handle had a distinctive foil-like grip to enable a number of handling options. Many variations on the F–S fighting knife exist in regards to size of blade and particularly of handle. The design has influenced the design of knives throughout the many decades since its introduction.
