How many people in the LUK SIU FUNG saga could pull their weapons free of the grip of the title hero's Ling Sai 1 Finger?

As far as I can tell, these individuals could:

1. Sai Mun Chui Sheut

2. Yip Goo Sing

3. Old Sabre Tyrant

4. Gung 9

I suspect that these might:

1. Dook Goo 1 Hok

2. Yuk Lohr Saht

Anyone else?
