In LUK SIU FUNG, the title character's signature move of catching swords (and other weapons) between his index and middle fingers was regarded as a unique and much admired ability. Even sword gods such as Sai Mun Chui Sheut and Yip Goo Sing openly admired the skill.
For elite level fighters, however, is such a move really that difficult to pull off? In various adaptations, both Gu Long and Jin Yong characters (including the Greats of the CONDOR HEROES TRILOGY) are observed pulling off similar moves at various times. Is "Ling Sai 1 Finger" really all that unique a skill?
