In order to evaluate hardness of a knife edge of swords, the damping hardness of a vegetable knife made of steel was investigated by using Herbert pendulum type hardness test. Stably swing behavior of Herbert pendulum on the knife edge of the vegetable knife was observed. Reasonable damping hardness of the knife edge of the vegetable knife can be obtained, although a knife edge is special shape as specimen. Therefore, hardness of a knife edge of swords can be reasonably evaluated by using the Herbert hardness test.
