The ancient, traditional Japanese knives are also known as ‘Wa-Bochos’ which could be dated back to the era where the Japanese Samurais first appeared. Similar methods to make Samurai blades were actually applied to make the first versions of the Wa-Bochos and even the Japanese-style kitchens we have today.

The Kataba or the Fluted Blade

The Kataba or also known as the beveled or fluted blade has distinctive features which made it different from the Western-style knives commonly used today for the cutting of vegetables, meats, and fruits. The Kataba knife is different from the ordinary knives we know as its outer blade is very well sharpened with a fluted edge, while the inner blade remains somewhat flat. The knife’s surface is also a little curved or concave is shape, marking a few similarities to knives equipped with emptied edges. The reason why most professional Japanese chefs prefer the Kataba is mainly due to its excellent capability to create clean-cut slices and enable them to separate or detach the meat easily when they are stuck to either side of the blade. As Japanese food often features raw ingredients like fish, squid, or jellyfish, the beauty of these dishes is a number-one factor that won the hearts of diners. Therefore, not only does a knife has to perform the tasks well, but it also has to be sharp enough to make clean-cut slices for the aesthetic required in the dining of Sashimi, as a rough-edged piece of Salmon would not make a very good impression.

There are the two main types of Wa-Bocho knives: Kasumi and Honyaki. The Kasumi knife comes with a combination of two-blade layers which were technically forged together to create one merged blade. The Kasumi knife is made out of both iron and carbon steel, where the spine which stretches to the end of the blade is made out of iron and the backside of the blade is made up of carbon steel. This typical knife is made to simply allow users to achieve easier cuts and is also recommended for beginners and intermediate users. The Honyaki knife is mostly made out of carbon. This high carbon-containing blade is repeatedly hammered to create a blade shape and also to enable the carbon molecules to spread thoroughly through the entire blade. This special technique aids in the removal of all impurities to form a true, pure steel blade. This knife is a little fragile compared to the Kasumi knife but it is widely used among professional chefs and those who are masters in the crafting of delicate Japanese cuisine.
