Our Testing Experience

First Impressions

When I first took the MIYABI Kaizen 9.5-inch Bread Knife out of its box, I was impressed by its sleek, authentic Japanese design. The blade felt light yet sturdy in my hand. I immediately noticed the thin profile of the blade, which seemed different from the thicker knives I usually use. I decided to test it right away on a fresh loaf of sourdough bread. As I sliced, the knife glided through the crust smoothly, making clean, even cuts without crushing the soft inside. It was clear this knife was something special.

Daily Use

Over the next few days, I used the knife for all kinds of bread — from crusty baguettes to soft sandwich loaves. Each time, the VG10 super steel blade maintained its sharpness and precision. The knife felt balanced and comfortable, which made slicing effortless. I also appreciated how quiet it was compared to other serrated knives; it didn’t tear or squish the bread. Using it daily made me look forward to my morning toast!

Key Features in Action

The thin Japanese blade profile really stood out during my tests. It allowed the knife to slice through bread with very little resistance, which helped keep the loaf intact. The hand-honed edge, sharpened through the three-step Honbazuke process, made a big difference too. The edge was incredibly sharp and stayed that way longer than I expected. I could tell this blade was crafted with care and precision, which made each cut feel smooth and controlled.

Long-Term Performance

After using the MIYABI Kaizen knife for several weeks, I noticed it continued to perform as well as on day one. Despite frequent use, the blade remained sharp and required minimal maintenance. The high-quality VG10 steel resisted rust and corrosion, keeping the knife looking great. Even after slicing tough crusts, the blade didn’t chip or dull quickly. Overall, this knife proved to be a reliable and durable kitchen tool that I’m happy to keep using every day.
