Why It’s Great

The Above-the-Board Knife

Hulling strawberries, slicing a peach, coring an apple: this is the work our paring knife was born to do, and it’s very good at it.

Precision Is the Point

Every design decision, from the blade length to the bolster, is about giving you control for the close, careful in-hand cuts that paring work requires.

The Spine and Bolster Make It Easy

Rounded and ergonomic, they reduce pinch-grip finger pressure so you’ll stay comfy over long prep sessions.

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.

3.5" ACUTO440 Paring Knife in Black

The 3.5" Paring Knife (ACUTO440) in Black is Misen’s smallest prep knife, built for peeling, trimming, and precision cuts where you want control in the hand. It’s especially handy for quick, delicate tasks like hulling strawberries or slicing a peach, when a larger knife can feel oversized.

What sets this paring knife apart is its AICHI ACUTO440 Japanese steel, chosen for exceptional sharpness, edge retention, and corrosion resistance. Misen also notes lab-tested rust resistance, including performance after being submerged in water for 50 days and up to 100 dishwasher cycles, helpful context if you cook often and want a blade designed to stand up to real-world kitchens.

In use, the compact blade length supports tight turns and fine detail work, while the rounded spine and bolster are designed for a more comfortable pinch grip. The grind is 50/50 symmetrical with a 14° edge per side, a practical, straightforward format for controlled slicing and trimming whether you are right- or left-handed.

If you’re building out a lineup, this knife pairs naturally with other focused tools from Misen’s Single Knives selection, or you can compare styles across the full kitchen knives range to cover bigger chopping and slicing jobs alongside handheld prep.

For care, Misen recommends hand washing and drying immediately after use, plus sharpening every 4 to 6 months. One more note that helps set expectations: high-carbon knives may show cosmetic discoloration after exposure to acidic foods and or salt, and the brand clarifies this is different from rust, which is extremely rare. For deeper guidance, see Acuto Knives Care.

Frequently Asked Questions About paring knives

What is this 3.5" paring knife best used for?

The blade is made from AICHI ACUTO440 Japanese steel. Misen highlights this steel for exceptional sharpness, edge retention, and corrosion resistance, along with lab-tested rust resistance for added peace of mind in everyday kitchen conditions.

How do I care for the blade day to day?
