PATENT ROSTFREI Vintage 21cm Italian OTF DA automatic knife

PATENT ROSTFREI Vintage Italian OTF DA automatic knife. The knife came direct from Italy last year along with some New Old Stock knives from the 1970s. I believe these were made in Maniago by Rosa Uliana Primo. The knife measures 21cm open. The blade has been lightly sharpened and is 99% full with nearly all of the factory finish intact and is stamped PATENT ROSTFREI on the ricasso. The frame appears to be non-magnetic cast and the button is also metal and pinned. The black synthetic scales are in great condition with just a bit of shrinkage and a slight curve by the button that doesn't seem to affect anything. Just some light handling marks on the scales. The DA (double action) knife functions great with blade shooting out when you push forward on the button and closing when you pull back on the button. EX+ condition.
