This is a vintage Rostfrei "Earl" sized folding hunter, manufactured circa 1980s in Seki, Japan by Seizo Imai for Herbertz for retail in Germany. Made with outstanding quality like you would expect, it is a similar design to the Puma Earl from that period. It measures 3.5" closed and features a gray micarta handle with stainless steel blade. Blade has a excellent action and tight lockup. A scarce recent find from knife distributor warehouse.
