But if you have a counter weight on the opposite side of the pivot, it means you're aren't holding the "business end" from as far as you can, which means you have a shorter moment arm (which is the whole point of a counterweight. No one wants a building crane whose operator is miles away from whatever it's lifting!). But for a slashing/chopping weapon, it's easier to just hold it from as far as you can from the blade increase the arm of the moment and therefore the force applied to the blade. That way, you not only make your weapon lighter (no counterweight = less mass on the handle = you can add more mass to the impact end), but also gives you extra reach.
