NIMAI-HIROGE(Spreading Two Sheets) NIMAI-HIROGE is the special skill in Echizen city only. It is outstanding method. The spine of blade requires thickness for sturdy and around the edge needs to spread to thin edge in order to improve sharpness. These requirements are met by hitting two blades together at a time. If two blades are hit together at a time, the temperature is hard to fall. Two blades prevent to be cool down fast. So blacksmiths can hit two blades many times in a short time. If only one blade are hit, the blade is cool down fast, they must put it into kiln for heat again. Then carbon runs away from the blade, the blade will become weaker. This skill looks easy, but it is very hard. Even a skillful blacksmith could not do this well for 5 years.
