Vintage Rostfrei G. Frasnelli 21cm Italian CONCORD OTF DA Black automatic knife made in Italy in the 1970s or 80s most likely. The knife measures 20.7cm (8.1 inches) open and 4 7/8 inches closed with non magnetic black metal body. The spear point blade is 100% full with original finish and is etched G. Frasnelli on the face and the ricasso (tang) is stamped Rostfrei. The frame (housing) is black coated metal and non magnetic and has the word CONCORD in white letters below the button with a few scuffs down to the metal on the side. The knife works great with blade opening fully and locking when the switch (button, knob) is pushed forward and retracts fully when it's pulled backward. EX condition
