Moritaka Hamono: One of Japan's Oldest Knife Forges

Moritaka Hamono: One of Japan's Oldest Knife Forges

When we talk about Japanese knife makers with serious history behind them, most have a few hundred years under their belt. Moritaka Hamono has over 700. Founded in 1293 during the Kamakura Period, this family forge in Yatsushiro, Kumamoto has been shaping steel continuously for 27 generations — and the knives coming out of that shop today are every bit as exceptional as that lineage suggests.

If you've ever held a Moritaka and wondered what the story was behind it, this one's for you.

Who is Moritaka Hamono, and how old is the forge?

The Moritaka story starts with a swordsmith named Kongohyoe Minamoto no Moritaka, who began forging blades in 1293 for Buddhist priests at Mt. Homan in Dazaifu, Fukuoka. For the first 13 generations, the family's entire output was sacred: tachi and temple blades crafted for the monastery, blending battlefield reliability with spiritual purpose.

Then, in 1632, everything shifted. The Hosokawa clan — the feudal lords of Kumamoto — relocated south to Yatsushiro, and the Moritaka family followed. They set up their forge near Myoken Shrine and continued producing swords for the domain's guards. That forge hasn't moved since.

When the Meiji Restoration ended the samurai era in the late 1800s and sword-carrying was banned, the Moritaka family did exactly what the great bladesmiths of Seki City did: they pivoted. Master swordsmith Chuzaemon Moritaka made the call to take 600 years of forging knowledge and apply it to kitchen knives. The decision turned out pretty well.

What makes a Moritaka knife different?

Today the forge is run by the 27th generation — Tsunehiro Moritaka — along with a small team of just one master craftsman and one apprentice. That's the whole operation. Every single knife is still hand-forged, and it shows.

Here's what sets Moritaka apart from the rest of our lineup:

  • Aogami Super (Blue Super) Steel: This is widely considered the most capable high-carbon steel you can put in a kitchen knife. Heat-treated to 64–65 HRC, it takes an insanely refined edge and holds it for a long time. Yes, it's carbon steel, so you need to wipe it dry after use — but the performance trade-off is more than worth it for anyone serious about their knives.
  • Kurouchi Finish: That dark, almost matte surface on the blade isn't just for looks (though it does look incredible). The kurouchi finish is the raw blacksmith scale left on the blade during forging — it's a direct visual record of the heat and hammer work that went into making it. No two are exactly alike.
  • Warikomi Construction: Moritaka uses a laminated steel construction where the hard Aogami Super core is sandwiched between softer iron cladding. This gives you a razor-sharp, high-performance edge while keeping the blade flexible enough to resist chipping in real kitchen use.
  • The Stainless Tang: Here's the detail we really love. Moritaka pioneered and patented a stainless steel tang welded to each blade. On a carbon steel knife, the tang (the part that goes into the handle) is usually the first thing to rust if moisture gets in. Moritaka solved that problem decades ago. It's a small thing that makes a huge difference in the long-term health of the knife.

Why does Coutelier carry Moritaka?

We are pretty selective about what ends up on our shelves. Moritaka made the cut because they represent something genuinely rare: a forge with the history of a museum piece and the performance of a professional tool. These aren't pretty knives made for display — they're working blades with a dark, utilitarian beauty that gets better the more you use them.

The kurouchi finish means the blade develops character over time. The steel rewards anyone who takes the time to learn how to maintain it. And the fact that a family in Kumamoto has been doing this exact work for over 700 years, with almost no outside help, is something we find hard to ignore.

Which Moritaka knives does Coutelier recommend?

We carry several Moritaka shapes in the shop. Here are the ones we keep coming back to:

Moritaka AS Gyuto

The workhorse. The Aogami Super Gyuto is the knife we point most serious cooks toward first. Available in 210mm and 240mm, it's got a flat profile that excels at push-cutting and a tip thin enough for detail work. Once you get the edge dialed in on a whetstone, it is genuinely one of the sharpest knives you'll ever use in a kitchen.

Shop the Moritaka Gyuto.

Moritaka AS Nakiri

If you do a lot of vegetable work, the Moritaka Nakiri is a revelation. The flat, rectangular blade and thin-behind-the-edge geometry make it a laser through produce. The kurouchi finish gives it that raw, no-nonsense look that feels right at home on a cutting board piled with herbs and alliums.

Shop the Moritaka Nakiri.

Moritaka AS Chinese Cleaver

This one surprises people. It looks like a big, intimidating slab of steel, but the Moritaka Chinese Cleaver is remarkably thin and nimble for its size. It's become a cult favorite among chefs who do high-volume vegetable prep and want a single blade that can handle everything from a butternut squash to a fine brunoise.

Shop the Moritaka Cleaver.

Moritaka AS Kiritsuke

For the cook who wants something with a little more presence on the station. The Kiritsuke's angular K-tip is both a status symbol and a genuinely useful feature for push-cutting and detail work. The 240mm length gives it serious reach. This is a knife that means business.

Shop the Moritaka Kiritsuke.

Are Moritaka carbon steel knives high maintenance?

We get asked a lot whether Moritaka knives are "high maintenance." The honest answer: a little, yes — but not as much as people fear. Wipe the blade dry after use, give it a light coat of oil if it's going to sit for a while, and don't put it in the dishwasher. That's really it. In return, you get a knife that sharpens faster than stainless, takes a keener edge, and has a character that stainless just can't match.

If you're new to carbon steel and want some guidance on keeping your Moritaka in great shape, swing by the shop. We're happy to walk you through it.

Where can you buy a Moritaka knife?

Moritaka knives are the kind of thing you have to hold to fully understand. The weight, the balance, the way that kurouchi blade looks under the shop lights — it doesn't fully translate through a screen. Come find us on Oak Street and we'll put one in your hand.

And if your current knives need some love before you're ready to invest in something new, we do professional whetstone sharpening right here at the shop. Drop them off and we'll get them back to you in top shape.

Frequently asked questions

How old is Moritaka Hamono?
Moritaka Hamono was founded in 1293 during the Kamakura Period, making it over 700 years old. It has been run by the same family for 27 generations and originally forged swords before transitioning to kitchen knives after the samurai era ended.

What steel do Moritaka knives use?
Moritaka knives use Aogami Super (Blue Super) carbon steel, heat-treated to 64 to 65 HRC, in a laminated warikomi construction with softer iron cladding. The steel takes an extremely fine edge and holds it well.

Do Moritaka knives rust?
The carbon steel blade will rust if left wet, so it should be wiped dry after use and lightly oiled for storage. Moritaka pioneered a patented stainless steel tang, which protects the part of the knife most prone to rust inside the handle.

What is a kurouchi finish?
Kurouchi is the dark, matte blacksmith scale left on the blade during forging. It is both decorative and functional, offering some corrosion resistance on the cladding, and no two finishes are exactly alike.

What is the best Moritaka knife to start with?
For most cooks, the Moritaka Aogami Super Gyuto in 210mm or 240mm is the best starting point. It is the most versatile shape and handles the majority of kitchen tasks.
