3.5 inch Paring Knife ACUTO440 Description

After 10 years of R&D, the next generation of Misen knives is here—and they’re the best knives we’ve ever made. Our new blades are forged from AICHI ACUTO440, an innovative high-carbon stainless steel that’s also (drumroll, please) totally rust-proof. Add a redesigned pinch grip for added comfort, and the same razor-sharpness and edge retention of our bestselling original knives, and you’ve got a pro-quality knife that you can use every day.

Our 3.5” Paring Knife 2.0 is the sleeper hit of your knife drawer, perfect for slicing smaller veggies like radishes or mushrooms, peeling garlic, or mincing a shallot. But this knife really shines at handheld tasks like cutting up a ripe peach in-hand, hulling strawberries, or carving a perfect curlicue of lemon peel for your cocktail.

Why The 3.5 inch Paring Knife ACUTO440 is Great

  • AICHI ACUTO440 Steel: Pro chef-quality Japanese high-carbon stainless steel is hard and durable with great edge retention. (Translation: less sharpening, more cooking.)
  • Rust-Proof (We Tested It!): The blade’s extremely high chromium content (16-18%) means you can cut acidic foods, air-dry, or even run through an accidental dishwasher cycle without a speck of rust.
  • New Ergonomic Rounded Spine - We listened to your feedback and made this our most comfortable knife to hold, even during long prep sessions.

Frequently Asked 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 50 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 50 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.

    Perfect parer—at a ridiculously low price!

    I bought a “petty” knife from Misen a couple of years ago, and have loved it— that was on top of a full+ set of well-maintained Wusthoffs. When I saw this paring knife for an absurd price, I bought one…and couldn’t believe how great it felt in the hand, and (of course) cut. I just bought 5 for the Xmas gifts I exchange each year w 5 colleagues, and am thinking I should buy another 5 or 6 for random gifts (for people I particularly like)!

    My Misen petty knife also has a red handle, but is a different sort of steel from these, I think. Both fantastic. I’m not sure why these are being closed out—and not sure how they could be improved upon—but I don’t think a better paring knife could be found. I LOVE THESE!

    Sharp and comfortable handle

    I have always loved my Mison products and the 3.5 inch paring knife is no exception. It is sharp, easy to hold, and well balanced.

    Great for fruit, vegetables and smaller item

    Do you like sliced up Grapefruit still in it's skin? I like Broccoli florets sliced to mix in my favorite summer Pasta salad.. If you like fruit sliced, this is a great knife. Like other Misen knives, this is super sharp. One must pay full attention when slicing with Misen knives.
