hello,
sae kye hyung sam bu uses the same patterns as world forms 1 and 2, the exception being the block is a choong dan yup mahk ki that is excecuted from hu kul ja seh, and the kick is a roundhouse, or tollyo cha ki, using the ball of the foot. ki haps are done on the final kick going each way, same as the previous 2 world forms.
hope that helps.
Tang Soo!
