  • A top-down view shows a person's hands slicing a head of broccoli on a white cutting board. The 5.5" ACUTO440 utility knife, with "MISEN" engraved on the blade, is positioned to cut the florets from the stem. Several broccoli florets are scattered across the right side of the cutting board. In the upper left, a Misen roasting pan holds more broccoli. To the left of the cutting board, a small wooden spoon with a pinch of salt is visible. In the upper right corner, a clear bowl contains more broccoli florets.

5.5 inch Utility Knife 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 5.5 inch Utility Knife is a Misen staff favorite, perfect for tasks when the Chef’s Knife is too bulky and the Paring Knife is too delicate. The Utility Knife is the perfect size for halving cherry tomatoes, de-seeding and mincing jalapeños, slicing cheese and salami for a charcuterie board, or supreming citrus. Cooks with smaller hands also love the Utility Knife as an alternative to the Chef’s Knife.

Why The 5.5 inch Utility Knife 2.0 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 2.0 Knives made of?

Our 2.0 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 2.0 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 2.0 Knives have a much higher chromium content (about 18%), which makes them significantly more corrosion (aka rust) resistant.

Our 2.0 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 2.0 Knives different from other high-carbon knives?

We wanted our 2.0 Knives to be high-performance tools that you could still leave in the sink overnight if you needed to. That’s why our 2.0 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 2.0 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 2.0 Knives in the dishwasher?

While our 2.0 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 2.0 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 2.0 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.
