Carbon steel is the traditional material used for creating Japanese knives. The key difference is that traditional japanese carbon steel knives are strong (literally harder than stainless steel) with a sharp edge that stays sharp for longer than stainless knives. Despite being a harder metal, carbon steel knives are also easier to sharpen (with a whetstone) than stainless steel knives, and a much sharper blade is possible.
Because of the alloys used, carbon steel knives may discolor, patina, and sometimes even rust if not properly washed and dried after use. Single bevel knives cannot be sharpened with a pull-through sharpener, so they must be sharpened with a whetstone.
Tsukiji Aritsugu's white carbon knives are made from a low contaminant, high carbon steel known for its ease of sharpening and ability to take a very fine, razor sharp edge. More difficult to forge and temper properly, this type of steel is a testament to the skill of the craftsman. Beloved by sushi chefs for its super fine edge, but it is highly reactive and will oxide (rust) easily. In addition, this brittle steel will lose its edge more quickly and require additional sharpening to maintain its razor-sharp edge.
