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.

    The Everything Knife

    I use this knife for most tasks. It’s thin enough for thin-slicing a tomato and robust enough to breakdown a chicken or split a rack of ribs. And it keeps a sharp edge. It’s easy to control and comfortable to hold. I’ve owned mine for ~3 Years, and I’m giving my son the same knife for his 20th birthday (he likes to cook!). 10 out of 5 stars!

    5.5 Utility Knife

    This is a daily go to knife. Super sharp and just the right size - for some cutting one does not need the 6.5 or 8-inch knife. Love, love this size knife.

    I use this every single day

    I have small hands and this knife is the perfect size - it’s the first knife I reach for, I use it at least once per day. I have a larger misen knife from 5 or 6 years ago that’s still in fantastic shape and sharper than it should be for how little i’ve tried to sharpen it. gives me confidence this one will last a long time as well!

    Perfect size and balance

    If you're not interested in working with an 8" chef's knife, this is a wonderful alternative. At 5.5", it's great for small and detailed tasks like deboning chicken.

    Pleasantly surprised.

    Was very happy to see the larger handle on this knife when I opened the package. From what I’ve seen with other knives the handles are not made for people with larger hands. Seems to be holding an edge quite well so far.

Why the White 5.5" Utility ACUTO Knife Is a Prep Essential

The 5.5" White Utility ACUTO Knife fills the gap between a full-size chef's knife and a small paring knife, making it the right tool for slicing citrus, trimming small produce, and portioning cheese or charcuterie. Its blade is forged from AICHI ACUTO440, a Japanese high-carbon stainless steel with higher chromium content than typical high-carbon knives, so it resists rust even after long soaks or repeated dishwasher cycles, while still holding a sharp edge at 58±2 HRC. The rounded spine and bolster give it a comfortable pinch grip during longer prep sessions.

If you find yourself reaching for this knife often, it pairs naturally with the 8" Chef's Knife for larger cuts and the 5" Serrated Knife for bread and delicate produce with tougher skins. For cooks building out a full lineup in the same steel and finish, the 7-Piece Knife Set covers most everyday tasks in one collection.

Like the rest of the ACUTO440 line, this knife should be hand washed and dried immediately, with sharpening recommended every 4–6 months to keep the edge performing at its best.
