Sterile 21cm Spanish OTF DA Aluminum frame vintage automatic knife

Sterile 21cm Spanish OTF DA Aluminum frame vintage automatic knife most likely made in the 1960s or 1970s in Spain. The knife measures 21cm (8 5/16 inches) open and 4 7/8 inches closed with polished aluminum frame. The flat spear point blade is 100% full with original finish with some light scratches and no markings on the blade (sterile). The black synthetic smooth scales are in very good condition with some marks/scuffs from handling. The knife works great with blade opening fully and locking when knob is pushed forward and retracts fully into the frame when knob is pulled backward. EX condition.
