In a recent post I did about the Altairs retractable blade from Assassins Creed, I made mention of the the characteristics of the ideal fighting knife. While any knife will only be at it’s best when used in manner and environment it was the designed for, most small, fast fighting knives have very similar properties.
Today, I thought I’d talk about a classic example of one of the best engineered fighting knives of the last century or so. The British Commando knife, AKA the Fairbairn-Sykes fighting knife:
Fairbairn-Sykes Fighting Knives
Fighting knives have been around since the beginning of man. Blades such as daggers, dirks and stilettos have always been popular fighting tools, due to their speed and flexibility. However the Fairbairn-Sykes fighting knife is a knife that has had a very profound influence of modern day combat fighting knife design. Developed in China, just prior to WWII, it was based on a design called the Shangai Knife:
This basic design was developed specifically for closed quarters knife fighting speed, agility and effectiveness. In contrast to the many other fighting knife designs, this was focused on very specific things. This fighting knife was designed to meet a very specific set of criteria. For instance, it had to be slim enough to be thrust between the ribs of an opponent. It had to be long enough to penetrate several layers of heavy clothing (like winter greatcoats and such,) and still strike vital internal organs. It had to be relatively small and easy to conceal. And it needed to be light, fast, and well balanced. But it also had to have excellent thrusting and slashing ability.
The FS (Fairbairn-Sykes) fighting knife design was the end result. Featuring a strong but narrow tapering double edged blade, it was one of the most well designed fighting blades of it’s time. After being adopted by the British army, and later variants of it by American, many other armies, it has had a significant influence on numerous combat blade designs since. Even your common boot knife and push dagger share roots with the FS design:
To be fair, the basic FS design is a revamp of a very old one. The idea of a strong, but slender, pointed, double edged blade has been around for a long time. However the FS design really brought it to the forefront of combat fighting knife design.
