What the testers found
Rated Highly Recommended by America's Test Kitchen, with the same full marks for sharpness as the Miyabi and a better handle score. "With a long; tall; and extremely keen, finely sharpened blade, this serrated knife nearly edged out our top choice." Its curved blade adds leverage for chopping. The catch: its rounded serrations "sometimes skidded and slipped on crusty bread instead of biting into it." ATK didn't test long-term durability.
