YoshiBlade is the world’s best ceramic knife. Own a professional-quality ceramic slicing knife at a fraction of the retail cost. Introducing the razor-sharp, feather-light YoshiBlade ceramic slicing knife. Unlike steel knife blades, which roll up along the cutting edge, ceramic knives like YoshiBlade stay razor-sharp because they’re made of diamond-hard, stain-proof zirconium oxide. In fact, this space-age material is so hard that professional chefs actually use ceramic to sharpen their expensive steel knives. Your YoshiBlade ceramic knife is rust- and stain-proof, easy to clean, and will not affect the taste or smell of food like steel knives.
