z INOX Spanish 10 inch stiletto Aluminum swivel bolster automatic knife

Spanish stiletto bolster release that measures 10 3/4 inches open. This knife has aluminum bolsters and liners and blade is stamped INOX. The scales appear to by faux stag made from some sort of synthetic material. The tang is also stamped PAT and a patent number, but can't make out the number. Knife works well with blade tip inside the liners when closed, good snap and tight lockup. No safety.
