STAINLESS ROSTFREI 20cm OTF Black DA vintage automatic knife

Vintage STAINLESS ROSTFREI 20cm OTF Black DA automatic knife likely made in Korea or Taiwan post 1990. It measures 19.9cm (7 13/16 inches) open and 4 13/16 inches closed with non magnetic metal plated bolsters and frame and black synthetic inserts. The flat spear blade is 99% full or better with original finish and ricasso is stamped STAINLESS ROSTFREI. The black synthetic scales are in very good condition with handling scuffs and scratches and no shrinkage. The knife works great with blade opening fully and locking when switch (button/knob) is pushed forward and retracts fully when it's pulled backward. VG+ condition. Unusual to not have any writing on the front handle (scale).
