Let’s be honest most people underestimate what a great bread knife can do. Until one morning, your beautiful sourdough loaf turns into a pile of crumbs. Or that expensive artisan baguette ends up smashed flat just trying to make a sandwich. If that sounds familiar, you’re not alone.
As a professional , I worked with blades in both professional kitchens and at home, I’ve learned that not all serrated knives are created equal. That’s what led me to the Miyabi Kaizen II 9.5-Inch Bread Knife, a knife that’s often praised for its precision, Japanese craftsmanship, and show-stopping design. But does it live up to the hype or is it just another overpriced pretty face? I spent a few weeks testing it to find out.
In this review, I’ll take you through my experience with the Kaizen II bread knife, how it compares to other premium options, and who it’s best suited for.
First Impressions: Craftsmanship That Speaks for Itself
When I first took the Kaizen II out of the box, I was honestly blown away. The blade has that signature Damascus steel swirl, 48 layers of stainless beauty, acid-etched for a darker, more dramatic look. And the handle? A black micarta grip with red liners, a mosaic pin, and a solid steel end cap screams attention to detail.
But here’s what matters more: It feels balanced. Not too light, not too heavy. Just right for control and comfort. The FC61 steel core is rock-hardened to 61 HRC, meaning the edge stays sharp longer and resists wear even under daily use.

Key Features and Performance
Serrated Edge Sharpened to Perfection
The blade is sharpened to an ultra-fine 9.5 – 12° angle using the Honbazuke method, a traditional three-step sharpening technique used in Japanese sword-making. That means serrated teeth that glide effortlessly through even the crustiest loaves without tearing the soft crumb inside.
FC61 Super Steel Core: Sharpness That Lasts
This proprietary steel offers excellent hardness and sharpness retention. Unlike cheaper blades that dull quickly, I found the Kaizen II maintained its edge through multiple rounds of bread, citrus, and even some meat slicing.
Damascus Pattern: Strength Meets Beauty
The 48-layer Damascus isn’t just for show, it adds durability and reduces friction. Food doesn’t cling to the blade the way it does with cheap serrated knives.
Micarta Handle: Built for Comfort and Control
Micarta is a resin-stabilized wood fiber composite, and here it’s contoured into a comfortable D-shaped grip ideal for right-handed users. It feels secure and slightly handle-heavy, which aids control during long slicing motions.
Performance Test: Is It Just for Bread?
Bread Test: Flawless Slices Every Time
This is where the Kaizen II shines. The knife slid through thick crusts without crushing the airy crumb inside. I didn’t have to use downward force, just a light sawing motion and it handled the rest.
Beyond Bread: Tomatoes, Pastries & More
It might not be designed for production, but the fine serrations worked beautifully. It sliced cleanly through tomato skin without juicing everything. On a cooled pork roast, it made neat, even slices surprisingly good for a bread knife.
Comfort and Balance in Extended Use
The handle fits snugly, and the knife feels responsive in the hand. It’s about 12.8 oz enough weight to let the blade do the work without tiring your wrist.
How It Performs in Kitchens
Cutting Bread: Crusty, Soft, and Everything In-Between
This is where the Kaizen II really shines. Crusty loaves? No problem. Soft sandwich bread? Clean slices, no squish. I even ran it through a still-warm banana bread loaf, still clean cuts with minimal crumbs.
Slicing More Than Just Bread
I also tested it on tomatoes, roast chicken, and even pineapple. The fine serrations handled it all. If you’re like me and don’t want to swap knives every two minutes, that versatility goes a long way.
Balance and Handling
At around 12.8 oz, it has just enough weight to make clean cuts without needing pressure. I liked that the weight sits closer to the handle, giving you more control during each motion.
