Baat Jaarm Dou Faat translates as 'eight chopping knives technique' , and not 'butterfly knives technique' as some have translated it, butterfly knives meaning Wuu Dip Dou. This advanced knives form is called 'eight chopping knives technique' because really the weapons are 'choppers' - they chop. There are eight sections to this form, and eight methods in the form to utilise the weapon. Many of the movements found in the Baat Jaarm Dou Faat comes from the boxing set - Tou Kuen, i.e Gan Sau becomes Gan Dou, Kwun Sau becomes Kwun Dou, etc.
Bou Faat - the footwork has some changes also, but the main area for development is the wrist and forearm which increases flexibility, strength and power. Each of the sections teaches the student to deal with weapons, i.e poles etc, coming in from different angles and also with multiple attacks. Like the Mok Yahn Johng and the Lok Dim Boon Kwun forms, this form is heavily supervised when learning by qualified instructors.
