Another common fallacy is that they are 'Two-handed swords'. They are not.
The extra-long grips are to counterbalance the blade. There are a few instances when the addition of the off-hand on the pommel end can be used to add power to a strike, usually when the opponent is already down and the need to counter is less important than forcefully finishing the argument. There are a few that are SO long that they must be used two handed, more like a short pole-arm, but that is a bit unusual.
