Compare the straight blade design of tangdao and Qing Jian! The arc shape of Japanese knife conforms to the physiological angle of human workers when drawing out the knife, which will be more efficient and faster! This is for each other, for the warriors who fight with their lives! The martial arts in the world are only fast and unbreakable!
Compared with Qing Dao, Japanese Dao is lighter and more convenient! Green knife users are generally very powerful! And the ancient Japanese samurai, short stature, strength is not as good as the Ming and Qing dynasties, so they are better at using the light and fast machetes!
In fact, in ancient wars, the shape and armament of weapons were related to the target of military strike or defense! The main function of Qing Dao is to chop armor and cavalry horses. While Japanese Dao, tangdao and Qing Jian are mainly beheaded! So the purpose is different, the figure is different, the strength is different, and the effect against the enemy is different! Then the shape and technique of the weapon are also very different!
This is my personal opinion. ...
