@mr meowgi I agree and disagree. With a long sword it is certainly terribly balanced for reverse grip but for a short sword it is well balanced to train for both offense and defense.
@HourglassVillain there are sword that work with reverse grip but they are within long dagger territory the ones they are using are normal swords neither greatsword nor shortswords closer to a bas**** sword which is between longsword and shortsword
its not gonna be effective with that style of combat
