The Broad Sword form
consists of hacking and chopping movements. Of all the Tai Chi
forms, this probably looks the most martial.
Partly due to the fact that the practitioner is
holding what is obviously a weapon, but also because the form is done with
speed, and occasionally, overt power.
Despite this the movements are still circular and based on the same principles
of the form.
The broad sword is sometimes referred to as the knife form as only one edge is sharp, like a knife.
Perfect does not mean perfect actions in a perfect world, but appropriate
actions in an imperfect one.
-R. H. Blyth
