{"type":"firestarter.listing","listing":{"id":"lst_gPjh9ihQ","product_name":"Higonokami Carbon Steel Japanese Friction Folder","category":"Pocket Folders","description":"Overview\nThe Nagao Kanekoma Higonokami is one of Japan’s most iconic folding knives: a minimalist friction-folder with roots dating back to the late 19th century. These knives are made by Nagao Kanekoma Seisakusho in Miki City, Hyōgo, the last remaining workshop legally permitted to use the registered “Higonokami / 肥後守定駒” name. This is the real thing—traditional, practical, and deeply collectible.\nAcross the Small, Medium, and Large sizes, the formula stays true to the classic Higonokami design: a laminated SK carbon-steel blade, a simple blackened steel handle with gold trademark engraving, and the signature chikiri lever for easy opening. Whether you want a compact everyday carry, a balanced all-around utility knife, or a larger pocket tool with more cutting length, this lineup offers an authentic Japanese folding knife for every preference.\nSize Comparison\n\n\n\nSize\nBlade Length\nApprox.
