Something a little out of the ordinary for you guys. I was reading another forum pertaining to real life swords and there was a thread about what sword would you make for yourself in an end of civilization type scenario where all you had access to is simple machine tools. One of the designs someone came up with looked kind of like a mini buster sword, people started joking about adding materia, it was re-drawn with slots (3 instead of the traditional 2 for some reason), ect...

Which got me thinking, in that scenario what three pieces of materia would you want to take with you?

The original scenario is as follows:
Let imagine that you are visiting friends or family in a place (cities, provinces, states) where private ownership of guns and swords are illegal. All sudden the area experience an economic catastrophe which lead to a state of general lawlessness. The mayor, cops, government officials all left and took their family with them to a better place. The government no longer exist and the citizens are left to fend for themselves. You are trapped there.

Gangs in large number began to terrorize the population. Gangsters organize in large group began to raid various neighborhoods, killing, raping, and pillaging. The gangsters armed themselves with various make shifted and improvised weapons. The weapons were created by gang members who learn how to make them while in prisons. They are well armed and well organized.

(and then lots of details about the constraints on the construction of the swords)
