The Science of Metal in the Best Samurai Period
Samurai governed Japan for about 700 years, from 1185 to 1867. The age of samurai is divided into some periods. According to a popular theory, samurais in the first period (the Kamakura period, from 1185 to 1333) are believed to be strongest and bravest. It is said that "You look like a Kamakura samurai" was the best praising words for samurais even in the last days of the samurai age.
