Civilian cold steel
Picked this up in my travels. Made by the Russian JSC Kalashnikov Concern (Izhmash) it is classified as the “HO-8 Household Knife.”
Based on the Udmurt “purt” style traditional blade (Izhevsk is at the center of the Udmurt population base), the handle is birch wood wrapped with leather strips with brass accents. The thick (3.5mm) single-edge blade is razor sharp (but soft) stainless with the classic industrial “arrow” stamp of the Izhmash factory and it has a decorative leather sheath. Overall length is just under 10-inches with a 5-inch blade.
The certificate is to accommodate Russian weapon laws as they pertain to post-Soviet knife laws in the country.
Since 1997, blades considered to be “military” or “hunting” styles, which are deemed “civilian cold steel” are tightly regulated and since 2016 have to be registered. As this is a “household” knife that fails to meet those tests due to blade strength, shape or size, it can be bought and sold over the counter– though not necessarily carried everywhere.
It would be interesting to see what the Rockwell hardness of this blade is. I would imagine somewhere in the 55 range as it feels akin to 420 stainless.
Looks very much like a Lapp leuku, aka a Sami knife, even to the style of sheath..
