It is a gem manufactured with an emphasis on the thinness of the blade, achieving a hardness of about 58°C with high-grade steel VG5 specifications. The eight-sided pattern is easy to handle in all dishes. The blade is hand-hammered, so the ingredients are cut off very well. The ripples of the three-layer structure determine the sharp sharpness. Each blade is finished by a cutlery craftsman in Seki City, Gifu Prefecture, and not only has a sharp sharpness, but also a sharp sharpness that lasts for a long time if you continue to sharpen it.　　The petty knife is useful in situations where you don't have to bother using a large knife, such as cutting fruit or slicing vegetables at the dinner table. Since it is small and turnable, it is perfect for detailed work such as removing potato sprouts, chopping condiments such as ginger onions, and cutting decorations. It would be quite convenient to have one as a sub knife. With the recent trend of small kitchens, it is also popular with women because of its easy handling.
