2nd Generation April 16, 2018 onwards: subtle wire brushed hamon, better blade flexibility. See videos below.
“Tsuru” (Crane) – For thousands of years the Japanese culture has treasured the crane as a symbol of honor and loyalty. The crane is believed to live for a thousand years. As a result, in the Japanese, Chinese and Korean culture, the crane represents good fortune and longevity. The Japanese also refer to the crane as the “bird of happiness”.
The crane symbol is used on many Japanese heraldic devices and is a theme in many famous works of art. It is a majestic bird which mates for life and is extremely loyal to its partner. The bird is strong, graceful and beautiful. Because of the great importance of the crane, the Japanese people feel that a person who folds 1,000 paper cranes will be granted his or her greatest wish.
The video below shows the difference in flexibility between the 1st Generation and 2nd Generation. The 2nd Gen is more flexible like a 1060 blade.
More subtle wire brushed hamon which looks like a real hamon.
