Guys, he's talking about weapon description.
If you want to change that description check itemname-e.dat from system, also you can change the grade from weapongrp.dat
Regarding the weapongrp.dat, it should be 5th after ItemSound, for example "ItemSound.itemequip_sword 10 371 138 8 5" 5 means s-grade, 4 means a-grade and so on.
