Moritaka does a phenomenal job with the Aogami Super (AS) steel at the core of their Supreme series. Heat-treated to HRC 64–65, these blades take exceptionally fine edges, hold their sharpness, and offer excellent edge retention. The core steel is clad in iron and finished in a rustic kurouchi style, lending both performance and character. Each knife is hand-forged with outstanding grinds, a testament to Moritaka's 700 years of blade-forging tradition. Even with this pedigree, the Supreme series represents one of the best values in handcrafted Japanese cutlery.
The 240mm kiritsuke is a versatile length, well-suited for both professional chefs and serious home cooks. It offers plenty of cutting power while remaining nimble and manageable on most kitchen boards. Unlike traditional kiritsuke profiles, this knife is ground 50/50, making it equally effective for both right- and left-handed users.
The blade is complemented by a striking custom octagonal handle crafted from 4,000-year-old bog oak, adding elegance to its proven performance.Blacksmith: Moritaka San
