Yoshihiro Kasumi White Steel Edo Usuba Traditional Japanese Vegetable Chopping Chef Knife, Magnolia Handle

The Edo Usuba is a traditional Japanese vegetable knife, reminiscent of a small cleaver, with a blunt tip that proves useful for tasks like cutting the eye out of a potato. Its substantial blade is capable of chopping through heavy root vegetables and slicing delicate tomatoes with precision. Known for its versatility, this knife excels in both fine and heavy-duty vegetable prep.

Our handmade Yoshihiro Kasumi knives are crafted with exceptional care by master artisans, combining the finest materials and traditional techniques to deliver knives of outstanding performance and value. Made from White Steel #2 with a hardness of 62 on the Rockwell scale, the steel is forged with iron to create the Kasumi mist pattern that not only enhances the knife’s appearance but also contributes to its durability and sharpness.

The Yoshihiro Kasumi Edo Usuba Vegetable Chopping Knife is designed with a cleaver shape and a straight cutting edge, making it perfect for chopping vegetables. Its single-edge blade ensures full contact with the cutting surface for a clean cut through the fibers of the vegetables. The knife is crafted using traditional Kasumi techniques, where softer steel is layered over a hard steel core. The high-carbon White Steel #2 core provides excellent sharpness and edge retention, while the surrounding softer steel offers added durability.

Handcrafted in Japan, this knife features a flat ground front (shinogi) and a concave ground back (urasuki), with a flat rim (uraoshi) for superior precision. The blade’s Kasumi pattern and White Steel #2 composition (with a hardness of 62-63 HRC) ensure a sharp, fine edge for intricate cutting tasks. It comes with a shitan bolster, a magnolia wood Saya (knife cover), a knife oil, and a rust eraser for proper maintenance. The D-shaped handle, crafted from magnolia wood, provides excellent balance and comfort during use.

For optimal performance, this knife requires regular maintenance with water whetstones. Hand wash and dry immediately after use, particularly when working with acidic ingredients, to preserve the knife’s sharpness and longevity. Avoid using it on bones, nutshells, or frozen foods. This Yoshihiro Kasumi Edo Usuba is a beautifully functional tool for any chef’s kitchen.
