Wuxia characters frequently carry and use sharp objects. It's an occupational hazard of their career choice.
Still, I'm sure there are a number of wuxia characters you wouldn't trust with sharp objects because they're psychotic/idiotic/sociopathic or some combination of these qualities. Who would you include among your list of such characters?
Mine:
1. Gwok Fu/Ah Chi (they share the # 1 position for obvious reasons)
2. Lee Mok Sau
3. Mit Jeut See Tai
4. Sor Goo
5. Princess Jianning
Hmmm...all women?
