This Vintage Smoky Mountain Knife Works Japan Model 3110B Balisong Knife is in good condition overall but does show expected signs of age, handling and use. The blade is well marked and production most likely took place sometime in the 80s or 90s. The blade has a clean edge however traces of wear from use can be noted. Modest "play" can be detected in the handles however the knife opens and closes as you would expect. $130 OBO
