Unlike Ssangsoo Gumbup, Woesoo Gumbup (one-handed style) uses only one hand in attacking and blocking having the sword on right hand and the scabbard on left hand.
As it is not using both hands, this style of sword techniques needs speed and turning, gathering, and distributing power of the body. Speedy block, attack and steps to the four cardinal points are the core of this style.
Woesoo Gumbup has two major styles - Sunbang Gumbup and Sungong Gumbup.
Sunbang Gumbup
The word Sunbang means 'defense first'. Thus, most of this style starts from protecting the body. But the protecting techniques are followed by prompt attack - normally stab and cut.
There are three types of block - Sangdan (upper), Joongdan (middle) and Hadan (lower) - Sangdan Bang uh (Bang uh = block) is to protect the head and Joongdan Bang uh is to protect the upper body while Hadan Bang uh is for the protect of the lower body. For Woesoo Gumbup uses only one hand, it need a lot of repeating exercise.
Repeated exercise of this block makes your body more securely protected and be ready for the next level - Sungong Gumbup.
Sungong Gumbup
While Sunbang Gumbup is 'defense first' style, Sungong Gumbup is 'attack first' style. The meaning of the word 'Sungong' is 'attack first'.
Prior to Sungong Gumbup practice, you need a lot of Sunbang Gumbup exercise as Sungong techniques need more of right position, stance and proper distribution of power.
