At 225 mm, the blade handles vegetables, meat, and fish in a single knife, while the angled tip allows clean cuts where a rounded profile loses precision. The blade height provides comfortable knuckle clearance on the board.\u003c\/p\u003e\u003cp\u003eForged in Sakai, the historic center of Japanese knife-making, by Yoshikazu Tanaka, certified Sakai Master Craftsman in 1996, this kiritsuke carries more than fifty years of forging expertise. The quench in pine charcoal heated to red heat, followed by rapid water cooling, is an ancestral technique of the Sakai tradition that Tanaka applies to every blade. The Makassar ebony handle, with its tight grain and contrasting dark brown veins on a near-black ground, is fitted with a dark collar that visually bridges the handle body to the blade.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAogami #1 (Blue Steel #1)\u003c\/strong\u003e is produced by Hitachi Metals from a Shirogami base with added chromium (0.2,0.5%) and tungsten (1.5,2.0%), and a higher carbon content than Aogami #2, at 1.25,1.35%. This composition yields longer edge retention between sharpenings, with the trade-off of requiring more passes on the stone to restore the edge. Hardness reaches 63,65 HRC depending on heat treatment. Like all non-stainless carbon steels, Aogami #1 develops a progressive patina with use, which is normal and expected. Wiping the blade immediately after contact with acidic foods slows unwanted oxidation.\u003c\/p\u003e\u003ch3\u003eCare\u003c\/h3\u003e\u003cp\u003eWipe the blade immediately after use.
