2nd Generation April 16, 2018 onwards: subtle wire brushed hamon, better blade flexibility. See videos below.
In Japan, dragons go by the names of Tatsu (Old Japanese) and Ryu (Sino-Japanese). Dragons in the West traditionally symbolize strength, ferocity, and wealth. They are a destructive force, but are also considered guardians. The Japanese, and the East in general, see dragons differently. They are generous, benevolent forces that use their strength to do good for mankind. Wisdom is another trait attributed to dragons.
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.
