PATENT ROSTFREI 21cm Italian All Metal Fishtail vintage switchblade knife

PATENT ROSTFREI 21cm Italian All Metal Fishtail vintage switchblade knife measures 20.7cm (8 3/16 inches) open with steel liners and button and nickel silver safety cap. The spearpoint blade is 99% full with original factory finish and some light scratches and one small pitted spot on the backside. The silver colored metal handles have a nice pattern lightly stamped into the surfaces that shows a little wear from handling, but mostly intact. The knife works well with blade tip below the liners closed, good snap and good lockup. Most likely exported to Germany and sold through Linder in the 1970s or 80s. Blade made shorter to comply with German import regulations at the time. Safety works. EX- condition.
