Rostfrei 21cm NATO MILITARY Green OTF DA vintage automatic knife

Rostfrei 21cm NATO MILITARY Green OTF DA vintage automatic knife likely made in Taiwan or Korea in the 1980s or 90s. The knife measures 20.8cm (8 3/16 inches) open and 4 7/8 inches closed with non magnetic metal frame painted green. The spear point blade is 100% full with original finish with a few light scratches and the ricasso is stamped Rostfrei. The frame is in nice condition with most of the original paint intact, but missing some on the front and near the back of the knife. Works great with blade opening fully and locking when the switch (knob/button) is pushed forward and retracts fully into the frame when pulled backward. VG+ condition.
