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.

    Most used knife

    This knife is almost out on our counter because we use it every day to slice breads and bagels. It is angled perfectly to obtain thin or thick slices. It has maintained its sharpness, and I have purchased several as gifts.

    Wow that's sharp

    I love Misen. I have a couple pans and now purchased a third knife. Did I need it? No. Was the price right and did I trust the quality? Yes! The personalization option, for free, sealed it for me.

    When I tried it the first time it just confirmed it was a great decision. Super sharp, the right size and I absolutely love it.

Why a 5‑Inch Red Serrated Knife Is Essential for Home Cooks

The Misen 5" Serrated Knife in Red is built from ACUTO440 steel, a high-carbon stainless alloy that holds a sharp edge through repeated use on foods that would dull a straight blade fast — think crusty sourdough, ripe tomatoes, citrus, and soft rolls. At five inches, it's compact enough for precise work yet long enough to saw through a full baguette in smooth, controlled strokes without tearing.

The serrated edge does the gripping so you don't have to press hard, which makes it especially useful for delicate produce where a slip could be dangerous. If you find yourself slicing a lot of larger loaves or deli meats, the 8" Serrated Knife in the same Red ACUTO440 finish covers more surface in each pass. For trimming tasks that call for a straight edge, pairing this knife with the 5.5" Utility Knife in Red gives you a well-matched set that handles the full range of mid-size prep work.

ACUTO440 steel is easy to maintain — hand washing and prompt drying keep the blade in good shape long-term. If Red isn't your preference, the same knife is available in Blue and other colorways to match your kitchen setup.
