>>63818575 (OP)>Was dual wielding swords actually a thing?Yes, it was rare overall outside of speficic instances.
In the West, the most common example was the rapier + dagger combo during the 16th and 17th century, which was mostly used for dueling, not on an actual battlefield.
The other notable example is Miyamoto Musashi's use dual wielding.
Dual wielding was pretty much unheard of in Japan until this decided this prodigy wanted to make a whole new "school" out of dual wielding.
He taught his students how to dual wield, but was pretty much the only samurai of note who used this technique.
If I'm not mistaken Musashi's use of dual wielding was mostly for facing multiple opponents, as well as for area denial.
The main observation about dual wielding is that the off-hand / main-gauche blade needs to be small in comparison to the main blade in your main hand.
At least that's what's historical examples tell us.
The samurai had the longer katana in the main hand and shorter wakizashi in the off hand.
Same with the dagger and rapier, the dagger is much shorter.
Doing a bit of research on this, other Historical examples include the Dimachaeri Gladiators in ancient Rome and there's a list of asian martial arts which do include dual wielding, but there's very little in the way of actual battlefield use for dual wielding. It's mostly used for dueling and martial arts.
