The convex 50/50 grind that defines the Moritaka Supreme line is not accidental - it is a deliberate geometry that provides exceptional ingredient separation, pushes food off the blade during cutting, and creates a more durable edge geometry than a flat grind at the same thickness. Moritaka Hamono has been developing this formula in Yatsushiro, Kumamoto Prefecture, for over 700 years.
With a 165mm blade length, the Moritaka petty crosses fully into utility knife territory - long enough to handle boneless proteins, citrus, and medium prep tasks on the board, still compact enough for in-hand work. The blade is paired with an octagonal magnolia handle with a buffalo horn ferrule.
What Customers Are Saying: Seven five-star reviews. Ryan calls it excellent and lighter than expected. Multiple reviewers praise the versatility of the 165mm format as the most useful petty length in the line - long enough for board work, compact enough for in-hand tasks.
Care Instructions: Aogami Super is a reactive carbon steel, and the soft iron cladding is also reactive - both the edge and the cladding will patina naturally with use. The kurouchi (black as-forged) finish on the cladding provides initial protection and the patina that develops adds further protection over time. Wipe and dry the blade immediately after every use. Avoid leaving acidic foods on the blade. Hand wash only, and never put it in the dishwasher. Apply camellia oil for long-term storage. Sharpen on quality water stones - Aogami Super at 64-65 HRC rewards careful technique and responds beautifully to stropping. Keep away from bones and frozen foods.
Each knife is made by hand so measurements may vary.

Excellent knife, lighter than I expected. Came with a cool blurb about the very interesting past of Moritaka. The best part however was in the notes I asked if there was a saya for this knife as I didn't see an option being sold bt CKTG. They replied they do not carry one, however when I received the knife they included a knife guard free of charge. Just an excellent touch to the already exciting event of receiving a new knife.

This is simply a wonderful knife. The steel is AMAZING and sharpens well on my Shapton stones. Perfect for work doing prep on a line in close quarters and glides through product. Will definitely be purchasing another Moritaka when needed. Definity a must to have in your kit!

This is a wonderful knife and it is my third Moritaka. This Supreme 165mm Petty has an excellent balance, the thickness if its spine support the knife very well. And of course, it is super sharp. My first Moritaka came with a beautiful rosewood handle, if they are continuing the use of the same kind of wood on their handles, that would be a 5 stars knife easily.

When I ordered I was a bit apprehensive about the kurouchi finish. But when I opened the box it was beautifully rustic. It was screaming sharp ootb. It feels great in my large hands. It has just enough height that I can use it on the board with a pinch grip. I put a 12 degree bevel on it and it chops and slices with no wedging or and minimal sticking. After a couple of weeks on onions, tomatoes and some proteins the exposed edge is developing an attractive blue patina. This is a great utility knife that fits nicely between your small petty and gyuto.Highly recommended.
