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

Holds a razor edge through heavy prep.

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.

    Wow, what a knife!

    Sharp, light but solid, easy to cut seared tuna, tomatoes, dice shallots, etc. Versatile, feels comfortable and well balanced when holding knife. Sharp is an understatement, it's very, very sharp.

    I was so impressed with mine I just purchased two more for my Sons. Misen's other knives are excellent too but this new style is exceptional!!

    My first “fancy” knife

    I’ve been using crappy knives I was gifted in sets for a while, but this has been well worth the money. The size is perfect for when I just have some veggies or fruits to cut up and I’m finding if I had to only use one knife, it would be this one. Just need a Misen chef’s knife now to complete my kitchen.

Why the 6.5" Gyuto Knife Is Ideal for Everyday Prep

The 6.5" Gyuto is a Japanese-style chef's knife sized for cooks who want precision without the bulk of a full 8" blade. Its shorter length makes it easier to maneuver through detail work — breaking down shallots, slicing herbs, or trimming proteins — while still handling most everyday prep tasks with confidence. ACUTO440 steel holds a sharp edge well and resists corrosion, making it a practical choice for daily use.

Because the Gyuto excels at push-cutting and slicing, it pairs naturally with a knife built for different jobs. A 5.5" Utility Knife in the same ACUTO440 steel handles smaller, more delicate cuts, rounding out your prep kit without overlap. If you want a complete matching set, the 7-Piece Black Knife Set brings the full ACUTO440 lineup together at a better value. All Misen knives carry a lifetime warranty against defects.
