Works Harder, Stays Sharper
The Misen 8" Serrated Knife is built around AICHI ACUTO440 steel — a Japanese high-carbon stainless with roughly 18% chromium, giving it lab-certified rust resistance through 50 days submerged in water and up to 100 dishwasher cycles. Its 25 wide-set wave-style serrations glide cleanly through crusty sourdough, ripe tomatoes, and delicate pastries without tearing, while an ergonomic rounded spine makes it comfortable to hold during longer prep sessions.
At 8.1 inches, this blade handles full loaves and larger produce with ease. If you prefer a nimbler option for smaller tasks like citrus or rolls, the 5" Serrated Knife in ACUTO440 covers the same steel and serration style in a compact package. For everyday slicing and trimming between these two sizes, the 5.5" Utility Knife in ACUTO440 pairs naturally with either serrated blade.
Care is straightforward: hand wash and dry immediately after use, and plan to sharpen every four to six months. If you want to build out a full ACUTO440 kitchen setup, the 7-Piece ACUTO440 Knife Set brings this same steel and rounded-spine design across a complete lineup.
