Our Testing Experience

First Impressions

When I first took the Miyabi Kaizen II 8-inch Chef’s Knife out of the box, I was immediately impressed by its weight and balance. The blade felt solid yet comfortable in my hand. I loved the look of the 48 layers of damast steel—it gave the knife a unique, almost artistic appearance. The size was just right for me, not too big or too small, making it easy to handle right away. I couldn’t wait to try it out on some vegetables and meat.

Daily Use

Over the next few days, I used the knife for all kinds of kitchen tasks—chopping onions, slicing tomatoes, cutting chicken, and even some tougher vegetables like carrots. The blade cut through everything smoothly and with little effort. I noticed it stayed sharp even after cutting through harder foods, which made cooking faster and more enjoyable. The handle was comfortable, and the knife didn’t slip in my hand, which gave me confidence while working.

Key Features in Action

The FC61 steel core really stood out during my use. The blade’s fine carbide distribution made it razor-sharp from the start and kept it that way for days. The double ice-hardened FRIODUR blade made a difference too—it felt very durable and resistant to dulling. I liked how the knife’s hardness at 61 Rockwell translated to excellent edge retention without being too brittle. Every cut felt precise, and the knife moved effortlessly through food, showing why these features matter.

Long-Term Performance

After using the Miyabi Kaizen II for several weeks, I’m happy to say it’s held up beautifully. The blade still slices cleanly without needing frequent sharpening, which is a big plus for me. The damast steel finish hasn’t faded or scratched much, and the knife remains comfortable to use every day. It’s clear that this knife is built to last and handle regular kitchen work with ease. Overall, it’s become my go-to tool for almost every meal prep.
