This is a nice vintage fixed blade letter opener knife. This originally came in a set of four knives in the box, which are being sold individually here. The box had "Made in Seki" in Japanese writing on the box. They are in lightly used condition or at least having light handling wear, may have light scuff on blade. Otherwise they are in great shape and have the traditional temper line on the blade. The sheath system is a matching wood that closes to meet the handle.
