I.O. Shen 10 in. (250mm) Bread Knife

Master the Crust: The 10-Inch Precision Bread Knife That Never Shreds


The Artisan Solution for Serious Bakers


If you have ever struggled with a standard 8-inch bread knife while tackling a wide, crusty sourdough or a homemade miche, you know the frustration of 'shredding' rather than 'slicing.' The I.O. Shen 10 in. (250mm) Bread Knife is the professional-grade answer to the artisan loaf. Its extra-long blade allows for a full, sweeping motion that clears the largest loaves in a single pass, ensuring clean, uniform slices every time.


The Science of the Steel


Unlike many serrated knives that use cheaper, softer alloys, I.O. Shen utilizes a proprietary VG-10 steel blend. This is a high-carbon super steel that offers outstanding edge retention. Because serrated blades are more difficult to sharpen at home, I.O. Shen prioritized the durability of the points. Note: This is the only knife in the I.O. Shen collection that does not feature the signature Triplex steel construction. The reason is intentional: a serrated blade requires the uniform hardness of their specialized VG-10 blend to maintain its aggressive cutting profile without the need for frequent professional servicing.


A Versatile Japanese Slicer


While designed for bread, the Japanese engineering behind this knife gives it a dual identity. The bow-shaped blade and surgical-grade serrations make it an exceptional choice for slicing through beef, roasts, and large poultry. The points bite into the protein while the 10-inch length allows for the long, clean draws required for thin, catering-style slices. Whether you are a professional chef or a dedicated home cook, the I.O. Shen 1027 is a high-performance tool that replaces two knives with one superior instrument.
