WÜSTHOF's precise, double serrated edge makes this bread knife distinctly different: unlike a single serrated edge, this knife has serrations within serrations, which means it stays sharp longer, requires less pressure and is suitable for very precise, smooth cuts. Bread with a hard crust is not flattened when cut with this double serrated blade, while bread with a soft crust is also cut cleanly without tearing the delicate surface. For optimal longevity, hand-cleaning the blades immediately after use is recommended.
