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.

    Must Have Knife

    You’re shopping Misen because you either know or have heard the quality of their cookware, tools, and knives is exceptionally high quality. Well it is. This knife is one of the examples of an exceptional knife for your kitchen. I practically use it daily, has excellent “hand feel”, and it has been my experience over the years I’ve owned this knife, as well as the others you want for a complete set, that all their knives sharpen it a razor’s edge. So stop procrastinating and buy it, you won’t be sorry.

    The real deal.

    Gotta admit... I was skeptical when I first read the rave reviews for the Mk 2 knives. Hadn't heard of this brand before, and did some quick research to expose the hype. Well, the more I researched, the more raves I found, so took a chance.

    Extremely sharp out of the box, comfortable handle, and nicely balanced. I'm not a chef, or a gourmand, but I do know tools pretty well -- this one, and the other I bought at the same time -- are a solid upgrade from all the other kitchen knives we own. Definitely recommend.

Why the 8" White Acuto Chef Knife Excels in Everyday Prep

The Misen 8" ACUTO440 Chef's Knife in White is built around AICHI ACUTO440, a Japanese high-carbon stainless steel with roughly 18% chromium — significantly more than standard high-carbon knives. That extra chromium is what earns its rust-proof designation: lab-tested to survive 50 days submerged in water and 100 dishwasher cycles without showing corrosion. At 58±2 HRC, the blade holds a razor edge through heavy daily prep, so you can go longer between sharpening sessions without sacrificing performance.

The hybrid blade shape handles the full range of cutting techniques — rocking, chopping, drawing, and slicing — while the ergonomic rounded spine and bolster make the pinch grip comfortable even during extended prep. At 230 g, it's substantial without feeling heavy. For smaller detail work alongside this knife, the 5.5" ACUTO440 Utility Knife in White pairs naturally, and the 8" ACUTO440 Serrated Knife in White fills in for bread and softer produce. If you want a matched set from the start, the 7-Piece ACUTO440 Knife Set in White covers every major cutting task in one cohesive collection.
