Instant Chucks

I need gopher-chucks!

—--The Chosen One, Kung Pow

Nunchucks are fun! The Ninja love them, and they are one of the most famous martial arts weapons around (next to the katana). The best thing about them is the fact that they are so easy to make! All you have to do, is take two random items, and connect them with a rope or a chain, and there you go! Instant Chucks!

Forget practicality, this one runs on pure Rule of Cool. Being such an easy weapon to make, a Combat Pragmatist can make some while locked in battle. If he is fighting multiple enemies, Asskicking ensues, if not, they will be discarded very quickly.

Sub-Trope of Double Weapon and Mix-and-Match Weapon.
