The NR-40 was a Soviet combat knife introduced in 1940 and used throughout World War II.
History
The Winter War revealed a number of deficiencies in Soviet weaponry; among other issues, the Soviet infantry lacked a good combat knife.As a result, in 1940, the Soviet Army adopted the NR-40.
"Black knife" division
NR-40 was mostly produced at the ZiK factory in Zlatoust, Urals.Once the Ural Volunteer Tank Corps was formed in 1943, all its soldiers and officers were supplied with a special issue of NR-40.
The formation was later named by Germans as «Schwarzmesser Panzer-Division». The unofficial divisional anthem mentioned the nickname as well.
Design
The NR-40 has a blade with a clip point, a large ricasso, a black wooden handle, and an S-shaped guard.The guard is "inverted" because standard Soviet Army grips called for holding the knife with the edge upwards.
