This is a vintage prototype pocket knife made in Seki, Japan by Seizo Imai circa 1980. It measures just over 2 1/4" long closed and features brass bolsters with wood inlays and stainless blade. 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. Acquired in Seki, Japan, we left the original stickers on the handle for identification.
