This is an excellent quality Magnum pocket knife made in Seki Japan in the 1980s by G. Sakai. This is the same knife that G. Sakai also made for Pacific Cutlery/Balisong at the same time period. This is an excellent quality folder featuring stainless steel blade and black rubber handles with nice lockup and quality feel and action. Measures 4" long closed. Unused old stock warehouse find from Seki. Light surface staining on blade can be easily buffed off. This is a high quality knife and very scarce.
