The Korean word Bonguk geom refers to both a sword and a sword skill which are said to have originated from the sword skills of the Hwarang from the Silla Dynasty. This is why the sword is also called Silla sword or singeom (신검). The term bonguk geom literally means 'national sword'. By including this skill in the Muyesinbo the Joseon warriors stressed the independent valor of Korean swordsmen. They do this by telling the story of Hwangchang, a boy from Silla, who killed Baekje's king while performing a sword dance, geommu, at the court.
