The sword is a widely recognised cultural symbol of Japan. Japanese swords are fundamentally weapons, and yet the high level of skill involved in the production of a beautiful and effective sword greatly increases its value, making them both sacred objects and symbols of authority. The way in which a particular sword is manufactured reflects the period in which it was made. By examining the finely polished surface steel and various patterns of the hardened edge, one can determine the province, school, and even maker. This illustrated handbook offers an educative look at the history, evolution, production, fittings and mountings, and appraisal of these elegant blades.
