A well balanced knife is such a kitchen essential because a sharp and well balanced knife helps you make quick work of those slicing and chopping tasks. The core of the Miyabi blade is very hard, so the knife will not have to be sharpened very often. The Miyabi 7000MC knives are also very durable. Several layers of metal are added to the strong Miyabi knife blade to help keep foods from sticking as you cut.
