Title: Vintage Japanese Yanagiba Sashimi Knife - Tokyo Nihonbashi Chiharu - Betsu-uchi Forged - New Old Stock Description: This is a genuine piece of history from Nihonbashi, Tokyo, the traditional center of Japanese cutlery. Unlike modern mass-produced knives, this Yanagiba (Sashimi knife) carries the soul of the Showa era craftsmen. The blade is engraved with the maker's name "Chiharu" and the stamp "Betsu-uchi". Betsu-uchi means "Specially Hand-Forged". It signifies that this knife was hammered and forged by a professional blacksmith, distinct from cheaper stamped manufacturing. The original sticker on the handle proudly displays "Tokyo Nihonbashi", proving its prestigious origin. [ Condition and Preservation Policy ] I am listing this item as "New Old Stock" (Unused, long-term storage). You will notice surface rust and patina on the blade. I have intentionally decided NOT to sharpen or polish this knife. Most sellers ruin vintage knives by grinding them on a machine to make them look shiny. I refuse to do that. The blade retains its full, original thickness and geometry. It is "Ubu-dashi" (fresh from the warehouse). This is a project for you. It is waiting for your whetstone and your skill. You have the privilege of applying the first "Honbazuke" (true edge) to this virgin steel exactly how you want it.

It is not a market find, but a genuine piece of history that has been sleeping in our home for decades. Shipping from Japan with tracking.
