A character trained to fight “Florentine” is a master at wielding two weapons at once. He adds +1 to his Fighting rolls versus an opponent with a single weapon and no shield. In addition, opponents subtract 1 from any “gang up” bonuses they would normally get against the fighter as his two flashing blades parry their blows.
Although the first sentence says that the character is a master at wielding two weapons, there isn't an explicit statement that two weapons are required to get the benefit. Does this mean that you could use a sword in one hand and your bare fist in the other to get the benefit (i.e. only be wielding one weapon)?
Moreover, the last few words suggest that they have to be bladed weapons (thus you couldn't do a sword and pistol), but again, it's not explicitly stated. I would think that maybe it's implied that you have to have two blades.
To further the confusion, the Edge summary table says the Edge provides "+1 vs. foes with single weapon and no shield; ignore 1 point of gang up bonus", saying nothing about requiring two weapons or the type of the weapon, implying it's on all the time (two weapons, one weapon + fist, or two fisted).
The spirit of the Edge seems to suggest that two bladed weapons are necessary, but I just don't see the words of the Edge explicitly saying it. How exactly is it supposed to work?
