AK47 Soviet style 22cm Automatic coil spring knife w Blued steel & wood scales USSR

AK47 Soviet style 22cm Automatic coil spring knife w Blued steel & wood scales hand made, most likely in the USSR sometime in the 1960s or 70s. It measures 22cm (8 11/16 inches) open and 4 11/16 inches closed. Most of the metal parts including the coil spring are blued and in great condition. The Saber grind drop point grooved blade appears to be nearly full and shiny with no identifying markings. The wood scales are in excellent condition. The knife works well with blade tip below the liners closed, STRONG snap and very good lockup with about 1/16" up and down at the tip. Does not rattle if shaken with blade open. I don't know who made this knife, or when. It is a very strong spring and you need to be careful both opening and closing this one and it takes a STRONG thumb to press the button and to lift on the blade release knob. Not for the faint hearted. ;^)  Nice old Russian automatic knife.
