Massive swords and axes that WAR and DRK have access to are generally supposed to be used as crushing weapons, given how long or wide or even both in rare cases with some slashing properties because of the blade being sharpened...

I'm just taking guess of that's weapons like that would have been used IRL in ye olde times...

Also in the God Eater games the Buster Blade has crushing properties as well as slashing properties, and then you have the Heavy Moon weapon(if Warrior and Dancer weapons had a baby) in God Eater 3 that has the same damage properties as the buster blade...
