For sale is a genuinely rare, museum-grade Soviet prison-made folding knife “Bochka” (Barrel), handcrafted by inmates 

in a Soviet correctional labor colony (ITK) in 1970.

These iconic knives were illegally produced in prison workshops from scavenged materials (aircraft-grade aluminum, brass, and repurposed steel) and became legendary within Soviet criminal subculture. Almost all examples that left the zones were destroyed or confiscated, making authentic early pieces from the 1970s exceptionally scarce today.

Year of manufacture: 1970 (early series)

Length closed: 10.3 cm

Length open: 16.0 cm

Body: fully threaded classic spiral “barrel” design

Mechanism: completely manual screw-out (no spring, extremely robust prison construction)

Condition: very good for a 55-year-old prison artifact. Honest signs of age and use, beautiful natural patina, no cracks or structural damage. Mechanism works perfectly.

This is NOT a modern Chinese replica – this is a 100% genuine 1970 Soviet prison original with real history behind it.

A must-have for collectors of:

Soviet prison and Gulag-era artifacts

Russian criminal folklore and zone culture

Handmade edged tools from forbidden environments

A true piece of dark 20th-century history you can hold in your hand.
