I have been buying Japanese kitchen knives at the flea markets. Some are brand names like Tedron Sword or MAC. Most have wooden handles. Most are marked Molybdenum Vanadium Steel Japan. Some say Taiwan but the steel is Japanese. Most have a sort of Wharncliff style point. These knives have thin full flat ground blades. They don't look like much, but they really hold an edge. The Germans have caught on, and they are starting to add Vanadium to their knives. The Vanadium Carbide inclusions in the blades have a RWC hardness of 82. The blades have RWC hardness of around 60. The wear resistance goes up when V is added.
