AK47 Soviet 22cm Vintage Swing Guard automatic knife

AK47 Soviet 22cm vintage Swing Guard automatic knife measures 22cm (8 11/16 inches) open with steel liners, bolsters, guards and button. Most likely made in the Soviet Union this one is most commonly referred to as an AK47 knife. It was believed that they were hand made using parts from AK47 rifles, but I can't confirm this. Regardless, it's a very SOLID knife with a STRONG action that is supposedly adjustable with a threaded rod connected to the compression spring. The long clip blade appears to be full with original finish and no markings. The knife is mostly steel with wood inserts, supposedly from wood rifle stocks. It works GREAT with blade tip seating deep, STRONG snap and good lockup open with a little up and down at the tip. The button is a little stiff to press, but not too bad. Knob above button releases blade to be closed when lifted. EX+ condition.
