What weapon would you use out of the 31 things!!!

[Griff]

31) I would use a combination of a bo staff with a blade at either end (commonly called a swallow, see chrono cross) and Jujitsu.

Something like Seong Mina in SC?

Kinda I guess, but a blade on each end, like this: http://www.vgmuseum.com/scans/scans4/cc.jpg

and jujitsu is a martial art like karate with more emphasis on pressure points and take downs.

edit: Zidane's ultimate weapon would be another good example.
