Yu Shin Gum Bup
Willow Spirit Sword Method
The Yu Shin Gum Bup was formally founded in 2008 by Ian A. Cyrus in order to bring accuracy
to the Yu Shin HapGi Mu Yae experience. Since the precursor to Hapkido (Yu Shin HapGi Mu
Yae), Daito Ryu Aikijutsu is, for the most part, based on extensive use of the sword, it was
necessary to formalize a sword curriculum in order to fully appreciate the depth of Hapkido (Yu
Shin HapGi Mu Yae). The curriculum of the Yu Shin Gum Bup was mostly derived from the
teachings of the Itto Tenshin Ryu as taught by Arvind Rajguru, Sensei, Joseph Simms, Sensei
and Fredrick J. Lovret, Sensei.
