This is a vintage prototype folding knife made in Seki, Japan by Seizo Imai circa 1980s for Virginia or Explorer. A sturdy folding hunter, it features a dense rubber handle with stainless steel blade. The handle has Super Sport on it. It comes with Parker sheath in box (may not be original but fits well). 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. After his passing, several vintage old stock models were found at his warehouse. This is one of these rare finds.
