This is a rare vintage Rigging knife made in Japan circa 1970. This is a factory sample prototype and still has the original factory sticker on the handle, dated 6/70. Made in the early years of the modern Seki knifemaking era, it features an all stainless construction. It has a marlin spike, blade, bottle/can opener, and the central liner forms a screwdriver tip. Nice collectable knife, in the original box.
