Aogami Super steel, perfectly executed, lies at the core of Moritaka Supreme knives. This steel is heat treated to an impressive Rockwell hardness of 64 to 65 HRC, allowing the blade to achieve exceptional sharpness and edge retention. The core is clad in reactive iron, while the traditional kurouchi finish offers some protection against corrosion. These knives remain fully reactive and should be kept dry and wiped clean after each use.
Drawing on more than 700 years of blacksmithing tradition, Moritaka produces hand-forged blades that embody both performance and heritage. This 150mm honesuki, designed as a poultry boning knife, is ground symmetrically, making it an excellent choice for both right- and left-handed users. The edge can be refined to a very acute angle on whetstones, though for poultry work it is advisable to keep the maker’s grind angle in place to reduce the risk of chipping around joints.
The blade is fitted with a traditional D-shaped chestnut handle capped with a buffalo horn ferrule, providing both durability and a secure grip. This combination of premium steel, expert forging, and thoughtful handle design makes the Moritaka Supreme Honesuki 150mm a superb tool for serious cooks seeking a handcrafted Japanese knife of the highest quality.Blacksmith: Moritaka San
