Certainly somewhere in the top 10 :

The deadly sock sword
Another one that would still rank in my top 10 : The keris...
Personally I still find the indonesian keris a weird weapon.
Althought it is historically embeded in our country (The Netherlands)
Logic as a weapon are far to be found in the keris.
No hand guard, not symetric, waivy, becomming smaller, thinner and more brittle over the years due to warangan.
I know there are all kinds of reasons why a keris is as it is, but still.
