The NR-40 (from Russian: нож разведчика, НР-40 nozh razvedchika meaning "scout's knife" or Finka) was a Soviet combat knife introduced in 1940 and used throughout World War II. The NR-40 has a 152 mm (6.0 in) blade with a clip point, a large ricasso, a black wooden handle, and an S-shaped guard. The guard is "inverted" (unlike most S-shaped guards, it curves towards the edge) because standard Soviet Army grips called for holding the knife with the edge upwards.
