Designed in early 1980s for Spetsnaz troops, the NRS-2 is still used today by some members of the Russian special forces.

The origins of this peculiar firearm can be traced back to the 1970s when engineers working at the Tula arms factory were tasked with creating “a close combat weapon for army reconnaissance units“. Under the oversight of designer, R. D. Khlynin, an early precursor to the NRS-2 known, interestingly enough, as the NRS, was developed that made use of the recently created SP-3 ammunition. These are specialised “silenced” bullets that had been developed during the Cold War period especially for spies and special forces units operating either covertly or behind enemy lines.


Although noticeably weaker than conventional bullets, SP-3 ammunition was considered to be acceptably powerful for single shot weapons like the MSP special compact pistol which was also developed under the supervision of Khlynin.

But the NRS wasn’t just a knife with a gun in the handle, it also doubled as a screwdriver, a saw and even had a tool built into the scabbard that could cut through wires up to 5mm thick. The scabbard was also insulated so that the knife could be used to cut through live electric cables, so long as the line wasn’t transmitting more than 380 volts.

A few years later when SP-3 ammunition was phased out in favour of the more powerful and reliable SP-4 ammunition, the NRS was redesigned by G. A. Savishcnev, I. P Shedlos, and V. Ya. Ovchinnikov to make use of it. Along with providing greater killing range, the NRS-2 included a number of other notable improvements such as an attachment for crimping primer caps and a sharper tip more suited for stabbing through thick cloth and thinly armoured targets. This new and improved gun knife officially went into service in 1986.


So how exactly does the NRS-2 work you ask? Well, to put it simply, housed just inside of the knife’s handle is a small gap, in which an incredibly rudimentary firing mechanism can be found. This mechanism can store one round at a time and needs to be removed once the round has been spent. The handle of the knife also features a safety switch to prevent accidental discharge and a set of iron sights to help with aiming.
