=== The advantages of metal hammering technique "Shibori" ===

Unlike forging of hot working technique, "Shibori" is Japanese traditional cold working technique.
Properly heat-treated and especially slow cooled iron can be worked by hand hammering at ordinary temperatures. Also when making like frying pans by forging, hammer is beating inside of iron sheets, but in "Shibori", it will be beating outside of them like squeezing.
By beating outside like squeezing without hardness change due to temperature change, iron sheet can be tough, lightweight and uniform thickness.
However, using "Shibori" technique for iron is very difficult and it needs more than twice the time and effort to use for normal soft copper, brass and silver. For this reason, ”Iron Shibori” is a very rare technique in the world.
