QJD Rostfrei (slant) 22cm Italian Stiletto swivel bolster vintage automatic knife

Vintage QJD Rostfrei (slant) 22cm Italian Stiletto swivel bolster automatic knife most likely made in 1980s or 90s in Italy for export to France. The knife measures 22.1cm (8.7 inches) open and 4 7/8 inches closed with brass liners and steel bolsters, button & safety cap. The flat grind blade is 97% full, or better and shiny with light scratches and the ricasso is stamped QJD over Rostfrei diagonally (slant). The horn scales (handles) are mostly black with some brown streaking on the back. The knife works well with blade tip deep in the well closed, fair snap, opens fully most of the time with firm press of the button and great lockup with just a hint of movement at the tip. Does not rattle if shaken with blade open. Safety works, but loose and doesn't stay in position. VG+ condition.
