Special scout knife (shooting).
By: Soviet combat knife, equipped with a firing device mounted in the handle. Designed for the SP-3 closed-type cartridge in the 1970s by Rafail Dmitrievich Khlynin on the instructions of the Ministry of Defense and the State Security Committee of the USSR.
With the appearance in 1983 of the silent PSS pistol under the much more powerful cartridge SP-4, the NRS knife served as the basis for the development of a similar product NRS-2 in order to unify the firearm arsenal for ammunition.
The knife is designed to defeat the enemy in close combat with a blade, when hitting or throwing, as well as a shot without noise and flame at a distance of up to 25 m. A saw for metal is cut on the butt of the blade. Detonator crimping pliers and a flat screwdriver are built into the scabbard. There is no recoil when fired.
