The Kan Dao lacks the finesse and speed of the Jian or normal straight sword. Nor is the Kan Dao quite as elegant and aerodynamic as a saber. The Kan Dao certainly lacks the exotic appeal of hook swords, sickles, butterfly wings and so on. The Kan Dao is just a tool for killing people. But it is a very good tool. Two Kan Daos of different weights and lengths were chosen. The asymmetry causes some interesting tactical considerations for the wielder, but even more so for the opponent. The Kan Dao as designed is intended primarily to hack off arms with heads and lower legs as secondary targets. That’s not to say we’d welcome being hacked in the upper leg – it is just that the thigh bone takes a lot of effort to cut through. The problem with the Kan Dao is it has limited defensive value. If the Kan Dao blow can be delivered the fight would not seem to be fated to last much longer. We’d not want to be parrying the thrusts of a skilled Wudang swordsman, especially if he has figured out that the Kan Dao is not much feared for its stabbing capabilities.
