Vintage C JUL HERBERTZ PATENT ROSTFREI 21cm Italian Out The Front Double Action Black metal button automatic most likely made in the 1970s by Rosa Uliana Primo in Italy for German Importer C Jul Herbertz. The knife measures 20.9cm (8 3/16 inches) open and just under 5 inches closed with chrome plated brass frame & bolsters. The flat spear point blade is 100% full with original factory finish and the face of the blade is etched C JUL HERBERTZ LIC 1062146 and the ricasso is stamped PATENT ROSTFREI. The black plastic scales are in very good condition with a few light scuffs from handling.
