10 Best Bread Knife For Sourdough 2026 in the United States

The Mercer Culinary M23890 Millennia Bread Knife is a solid choice for slicing sourdough bread thanks to its 9-inch serrated blade made from high-carbon Japanese steel. This material keeps the blade sharp for a long time, which is important since sourdough crusts can be tough to cut through. The wavy edge serration is designed to slice cleanly without crushing the soft inside of the bread, making it gentle yet effective. The knife’s blade length is ideal for handling larger loaves.

Its handle, made of Santoprene with textured finger points, offers a comfortable, non-slip grip that helps with control and safety during use. Weighing just 4.6 ounces, it is lightweight and well balanced, so it won’t feel heavy or tiring during repetitive slicing. However, the knife is not dishwasher safe and requires hand washing and careful drying to maintain its quality. While the stamped construction may be less durable than forged knives, the lifetime warranty provides some reassurance.
