Questions?

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.

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.

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.

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.

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.

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.

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. To remove discoloration, make a paste with baking soda and water. Apply the paste to the discolored spots, then use a soft microfiber cloth to gently rub the paste into the affected area to remove discoloration. Wash your knife with a soft sponge and warm soapy water, then dry right away. That's it.

I love it so far.
The knife has a nice heft, and ergonomic feel. We'll see how the edge holds up.

The 8" Acuto Chef's Knife is built around ACUTO440 steel, a high-carbon stainless alloy that holds a sharp edge through heavy daily use while remaining easy to maintain at home. At 8 inches, the blade length hits the sweet spot for most kitchen tasks — slicing proteins, breaking down vegetables, and fine knife work alike — without feeling unwieldy for cooks of any experience level.

A well-balanced chef's knife does most of the heavy lifting in a home kitchen, but a complete prep setup benefits from a few supporting blades. The 5.5" Acuto Utility Knife is a natural partner for smaller, more precise cuts, while the 5" Acuto Serrated Knife handles bread and delicate-skinned produce with ease. For those who want color-matched handles, this chef's knife is also available in Blue and other finishes to suit your kitchen aesthetic.
