This is a quality vintage butterfly knife, handmade in Seki, Japan, circa 1980. It is stamped "Handmade by Kim" and we believe this was made at the G. Sakai factory, where Pacific Cutlery balisongs were also produced. The quality of this knife is excellent. It features a 440 stainless steel blade etched Super Collection and a 3.5" long handle of solid machined nickel silver and has great feel to it with good action. It has the original factory edge and model sticker on the blade. This is a nice butterfly knife and a scarce addition to any knife collection.
