Pair it with

Basically a Navy Seal

Rust-proof after 100 dishwasher cycles.

Because it’s got more chromium than standard high-carbon stainless, ACUTO440's rust resistance is a lab result, not a marketing claim.

Works Harder, Stays Sharper

At 58±2 HRC, ACUTO440 has incredible edge retention without brittleness. That means you can put off sharpening it for longer.

Questions?

What are Misen’s ACUTO440 Knives made of?

Our ACUTO440 Knives are made with AICHI ACUTO440, an exceptionally corrosion-resistant Japanese high-carbon stainless steel. AICHI ACUTO440 is rust-proof, incredibly durable, and has excellent edge retention. What that means for you: less time cleaning and sharpening, more cooking.
What’s the difference between Misen’s ACUTO440 Knives and classic knives?

All of our knives are made from high-carbon stainless steel, which is what gives them their razor-sharpness and excellent edge retention. However, our ACUTO440 Knives have a much higher chromium content (about 18%), which makes them significantly more corrosion (aka rust) resistant.

Our ACUTO440 Knives also feature a rounded spine and heel (the back of the knife where the blade meets the bolster), creating a more comfortable grip over long prep sessions.
How are Misen’s ACUTO440 Knives different from other high-carbon knives?

We wanted our ACUTO440 Knives to be high-performance tools that you could still leave in the sink overnight if you needed to. That’s why our ACUTO440 Knives are made with AICHI ACUTO440, a Japanese high-carbon stainless steel that is more durable and easier to care for than other high-carbon knives, which are prone to rusting and/or chipping without proper care.
What do you mean by rust-proof?

Our ACUTO440 Knives are made with AICHI ACUTO440 steel, an exceptionally corrosion-resistant Japanese high-carbon stainless steel. Our knives have been lab-certified to withstand up to 100 dishwasher cycles, as well as 50 days of being submerged in water, without showing any signs of rust.
Can I put Misen’s ACUTO440 Knives in the dishwasher?

While our ACUTO440 Knives have been lab-certified to withstand up to 100 dishwasher cycles without showing any signs of rust, we generally recommend hand washing all of your Misen knives. Because our knives are extremely sharp, when they get jostled around in the dishwasher, the blade can cut through the soft materials that make up your dishwasher racks. Dishwashing can also damage your knives if the blade edge bangs against hard objects like flatware or pots and pans during the washing cycle.
How often should I sharpen my knives?

Whenever you start to notice your knife is slicing and dicing a little less crisply than usual, it’s time to sharpen. Although our ACUTO440 Knives can go long periods between sharpenings, we generally recommend getting them sharpened about twice a year for best performance. We also recommend regularly using a honing rod between sharpenings to keep your knife edge in good shape.
My blade has discoloration and/or staining. What is this?

While our ACUTO440 Knives are rust-proof, all high-carbon knives can experience some discoloration and/or staining with prolonged exposure to acidic foods and/or salt. This is purely cosmetic and is not the same as rust.

    Beautiful

    This is my second Misen knife, I've had the Utility Knife for 3 years and it's been the only thing I've used, and when I decided I wanted something a bit like a Chinese chef's knife or a santoku or nakiri for vegetable chopping, I saw that Misen had just come out with their spin on a nakiri, and its just as lovely as my Utility Knife.

    Just feels so good and nimble in the hand, so perfectly balanced and smooth, and I love the way they've designed this blade shape to be a bit closer to a santoku or cleaver than a traditional nakiri, sleek rounded contour. Beautiful knife

    Makes chopping veggies a breeze!

    Already had a chef’s knife from Misen, which I love. When I saw this announced I was quick to preorder and was not disappointed. The knife feels great in hand, looks stylish, and chops veggies with ease.

    Well balanced and sharp knife

    Knife works very well, it's a big blade but is very easy to use with small hands. cuts even tough squash easily.

    My Favorite!

    This is my fourth Misen knife purchase, all but one are the 5.5 versions, as I have small hands and prefer the agility afforded by a smaller knife. The Nakiri is hands down my favorite! I love the blade shape, it's thinness, the balance. I find it not only cuts vegetables with ease, but also delicate tomatoes, and is great for thin slicing cheese. It's the one I reach for more often than the others, as it has proven to be very versatile.

Why the Black Nakiri Knife Excels at Vegetable Prep

The 5.5" Nakiri knife is purpose-built for vegetable work. Its flat, rectangular blade makes full contact with the cutting board on each stroke, letting you slice, dice, and julienne with consistent, clean cuts — no rocking required. ACUTO440 steel holds a sharp edge well and resists corrosion, while the ergonomic black handle gives you a secure, comfortable grip through extended prep sessions.

Because the nakiri excels at vegetables but isn't designed for tasks like breaking down proteins or slicing bread, it works best as part of a broader knife setup. Pairing it with the 3.5" Black Paring Knife covers detailed work like peeling and trimming, while a 3-Piece Black Knife Set rounds out your kitchen with an everyday chef's knife in matching black ACUTO440 steel. If you prefer a different handle color, the same nakiri is also available as the Blue Nakiri Knife.
