Strengths
The user of the Meijin Meijin no Mi can instantly master any weapon they pick up, which allows them knowledge of how best to defeat someone who uses that type of weapon, and what weaknesses the weapon has. Strangely enough, the fruit sometimes makes the user more persuasive with their words, as words themselves can be considered a type of weapon. This is most prominant in the current user of the fruit, ???, who has been able to win battles with just his words, and even managed to convince a marine vice admiral to free him.

Weaknesses
The user suffers from standard Devil Fruit weaknesses. The fruit does not grant the strength, speed or stamina required to weild some weapons, only the knowledge, which can lead to a major weakness in the user's attack stratergy's.

The third non-standard weakness, is that the user cannot master things that they don't consider weapons.
