*British, PostWW2, 3rd Pattern Fairbairn-Sykes Fighting Knife, J. Nowill & Sons (Cross Keys *D), with Leather Sheath*
An exceptional example of the legendary WW2 Fairbairn-Sykes fighting knife, the iconic weapon of Britain’s Commandos, SAS, and Airborne forces. This 3rd Pattern dagger, bearing the desirable Cross Keys mark of J. Nowill & Sons, Sheffield, is a genuine wartime piece closely associated with the most daring special operations of the war. Compact, lethal, and instantly recognisable, the F-S dagger remains one of the most celebrated combat knives ever issued — and examples by Nowill are particularly sought after by collectors.
The knife features the classic 3rd Pattern ribbed copper-alloy grip, designed to provide secure handling even in wet or muddy conditions. The double-edged blade has the characteristic acutely tapered profile optimised for thrusting, with evidence of age-related wear and light surface pitting consistent with service use. The hexagonal pommel nut remains tight, securing the blade firmly in place.
It is accompanied by a leather scabbard, with belt loops and retaining tabs, showing age and handling wear.
Historical Note:
The Fairbairn-Sykes (F-S) fighting knife was designed by William Ewart Fairbairn and Eric Anthony Sykes, who developed their expertise in close-quarters combat while serving with the Shanghai Municipal Police before the war. Introduced to British forces in 1940, the F-S dagger quickly became synonymous with elite units.
The 3rd Pattern, introduced in late 1943, was the most widely produced wartime version, identifiable by its cast ribbed grip and thickened crossguard. These were issued to British Commandos, SAS, Airborne troops, and various special forces, including extensive use during the Normandy landings and subsequent operations across occupied Europe.
J. Nowill & Sons, established in Sheffield in 1700, is one of the oldest surviving British cutlers. Their Cross Keys trademark was registered in 1842 and remains one of the most recognisable Sheffield maker’s marks. During WW2, Nowill supplied F-S knives under government contract, and examples bearing their marks are highly sought after.
*Condition*
This knife remains in very good, service-used condition for its age. The blade shows areas of light pitting and age staining but retains its form with no structural issues. The ribbed copper-alloy grip has developed an attractive dark patina from handling and use, with some natural wear to the high points. The pommel nut is tight and secure, with no movement between the blade and grip. The Cross Keys and D maker’s stamps remain clearly visible and well-defined. The accompanying scabbard is well-fitted, showing typical wear to the leather body and retaining tabs consistent with age and use. Please see photographs as part of the condition report.
