10 Best Bread Knife For Sourdough 2025 in the United States

The Mercer Culinary M23210 bread knife is a solid choice for anyone looking to slice sourdough or other bread types with ease. With a 10-inch blade made from high-carbon Japanese steel, this knife promises sharpness and easy maintenance, making it a long-lasting addition to your kitchen. The wavy edge is particularly effective at cutting through crusts without crushing the soft interior, which is a must for bread enthusiasts. The ergonomic handle features textured finger points that provide a non-slip grip, enhancing comfort and safety during use.

One of the strengths of this knife is its excellent balance and lightweight design, weighing only 4.8 ounces. This makes it comfortable to handle, especially during extended cutting sessions. The knife is versatile enough to slice not only bread but also other foods like cakes, fruits, and even meatloaf, adding to its utility in the kitchen.

There are a few drawbacks to consider. The knife is not dishwasher safe, requiring hand washing to maintain its performance and longevity. This could be a hassle for some users who prefer the convenience of a dishwasher. Additionally, while its high-carbon steel blade offers durability, it may require more care to prevent rusting and maintain its edge compared to stainless steel options. Mercer offers a warranty for this knife, which covers defects in materials or workmanship, but it does not cover misuse or damage caused by improper care, such as placing the knife in a dishwasher.

The Keechee Adjustable Bread Slicer is designed especially for slicing sourdough and other artisan breads with ease and precision. It features a 9-inch serrated stainless steel blade that cuts through crusty loaves without crushing or tearing the soft inside, which is great for maintaining the texture of sourdough. What makes this knife stand out is its adjustable thickness guide that helps you slice bread consistently from thin to thick slices, perfect if you like variety or want uniform pieces for sandwiches.

The handle is made from lightweight, smooth bamboo, offering a comfortable grip that fits both small and large hands. It’s also designed to be ambidextrous, meaning left-handed users can easily flip the blade for comfortable use. Weighing just under 9 ounces, the knife is light and balanced, reducing hand fatigue during longer slicing sessions.

One potential downside is that this tool is bulkier than a traditional bread knife because of its bow-shaped frame and thickness guide, which might require more storage space. Also, while the bamboo handle looks attractive and feels nice, it may require some extra care to maintain over time compared to plastic or metal handles. Customers generally give it good reviews, though some mention the learning curve in using the adjustable guide effectively. This knife suits home bakers and bread enthusiasts who want clean, even slices and appreciate the ability to customize slice thickness. It may be less appealing if you prefer a simpler, more compact bread knife without extra features. It provides a clever solution for precise and safe slicing, especially if you bake sourdough or similar crusty breads regularly.

The blade features an ultra-sharp, serrated edge that helps in making clean, smooth cuts effortlessly. Made from high-quality stainless steel, the knife is durable and suitable for daily use. Its one-piece design ensures there are no parts that can wear out or loosen over time, contributing to its longevity.

Weighing 8.1 ounces, it offers a good balance, making it comfortable to hold for extended periods without strain. The ergonomic handle design fits comfortably in your hand and enhances ease of use, especially when slicing harder bread varieties. On the downside, the all-stainless steel handle might not offer as much grip as rubber or wooden handles, which could be an issue for some users.

Additionally, while the knife is dishwasher safe, hand washing might be better to maintain its sharpness over time. This knife is versatile and can also handle cutting cakes, pastries, and bagels, making it a valuable addition to any kitchen. Given its budget-friendly price, it is a strong contender for anyone needing a reliable bread knife for sourdough and other tough breads.
