This is a vintage Japanese crafted pocket knife made in Seki, Japan by Seizo Imai for Parker Bothers, circa 1978-1982. It comes with the original leather sheath. Seizo Imai was one Seki, Japan's finest craftsmen and most famous knifemakers of the modern era. His collaboration with Parker spanned nearly two decades. He made knives for Parker, Frost, Browning, Explorer, Compass, Condor, and many others, including his own brands Imax and Seizo Imai. His custom Loveless style knives are works of art. This is a very rare combo!
