Swords and Blades in One Piece have different "Grades" that reflect their quality. But how is a Blades "Grade" created?
We also know that supposedly that a "Grade" can improve over time with the right user, but who or what decides what a Blades "Grade" is?
Is the the Swordsmith that Forges it? And who are the ones who are keeping track of all the "Graded" Blades?
