INOX 33cm Italian Stiletto vintage 1980s Dark Horn automatic knife

Vintage INOX Italian swivel bolster stiletto automatic knife most likely from the 1980s. Measures a little over 18cm (7.25 inches) closed and 33cm (13 inches) open with brass liners that extend behind the guards on the top rear bolster only. Also that lined bolster is made of Nickel silver and the other 3 bolsters are steel. I've seen this on other knives from this period (1980s & 90s). The flat grind blade is full and retains all of the original finish and is stamped INOX on the ricasso. Very nice dark buffalo horn scales are in very good condition and are mostly black with a little light streaking with some light handling marks. Works like new. Blade tip deep in the well, strong snap and tight lockup. This is a swivel bolster knife so you press the button to open and you push down on the right finger guard on the top front bolster to release the blade to close. Safety works. EX+ condition.
