When Yeung Gor went to Dook Goo Kau Bai's cave after having lost his arm, he was presented four of Dook Goo Kau Bai's swords by the Divine Condor: the first sword, I believe, was known for its extraordinary sharpness and was used by Dook Goo Kau Bai in his youth. The second sword was the Flexible Sword. The third sword was the infamous Heavy Iron Sword. The fourth sword was the Wooden Sword (the last material sword that Dook Goo Kau Bai supposedly used during his lifetime).
How did Yeung Gor arrive at the conclusion that the Heavy Iron Sword was the right one for him? It was heavy, awkward, and blunt...the *last* weapon you'd imagine that a fighter who had just lost his right arm would want to claim as his new armament of choice. What led Yeung Gor to pick this sword rather than Dook Goo Kau Bai's other swords? I could see why he wouldn't want to use the Wooden Sword at that stage, but why not the first sword (the sharp one?) or the Flexible Sword?
