WW2 era OSS Drop Knife made during the war by Foster Bros from M1873 trapdoor spike bayonet blade, hard to find original metal scabbard included. Rare UNUSED condition – very hard to find this nice and complete.

Rare original WW2 era so-called “OSS Drop Knife” spike blade fighting dagger made from the the Indian Wars era Springfield M1873 trapdoor socket bayonet. This fighter comes with an equally scarce original WW2-era finished metal scabbard – both are in mega-rare unused condition. These unusual weapons were reportedly manufactured during the war by Foster Brothers Company (Foster Bros) under a contract for the US military. In order to satisfy the demand for much-needed fighting knives early in the war, Foster Bros manufactured these sturdy fighters from whatever obsolete bayonets and sabers Uncle Sam could find in arsenal storages. Forced to improvise during the wartime shortage of quality materials, Foster Bros had reserved to using cut-up garden hoses and metal scrap for handle materials. The result is this improvisation was a somewhat crude, but very effective and practical fighting knife.

Interestingly enough and in spite of its common name in the collectors’ circles, there is no evidence supporting the claim that these “OSS Drop Knives” were actually air-dropped to OSS operatives or local resistance behind enemy lines during the War.  This exact “OSS knife” type is illustrated on page 172 of the U.S. MILITARY KNIVES; BOOK IV published in 1973 by M. H. Cole, and on page 175 of the KNIVES OF THE UNITED STATES MILITARY WORLD WAR II book by Michael W Silvey – a well-established expert and the author of a number of books on the subject of the US military edged weapons (see the book’s scans attached).

This “D-guard” fighting knife is about 14″ /” / 35.5 cm overall; the blade is about 8-3/4” / 22.3 cm long. The blade is in excellent condition with most of the original bluing remaining, the tip is intact; no dings or edge nicks. Some light surface rust is noted for accuracy (cleanable). The four-point steel “D-guard” over rubber hose handle with a sharpened protruding scull crushed for a pommel.  The handle is in excellent condition; all parts are tight with no play. Hard-to-find original metal scabbard is included. These were finished during WW2 from re-purposed original M1873 scabbards.

This converted M1873 socket bayonet  – turned WW2 era OSS Drop Knife is a rare find these days, especially in minty condition. Most of the surviving WW2 era “OSS Drop Knives” are in private collections and are off the market. This WW2 era OSS Drop Knife / fighting dagger is one of the best American WW2 era “non-regulation” fighters with a lot of character and in excellent overall condition, you will not be disappointed!

This rare WW2 era OSS Drop Knife has not been cleaned or tampered with in any way, it is in 100% original “as is” condition; these are the actual photos.
