Maciejowski Chopper Earring (pair) curved grip

I designed most of these weapons after 13th century pictures from the Maciejowski Bible. We call this one the Maciejowski chopper, after its function. It chops. I tried a life size replica with a straight grip a while ago, and the momentum it has is really wonderful. If it doesn't chop, it will break something for sure. Or add a nasty dent to your helmet and/or skull. I'm wondering how the curved grip would impact balance and moment of inertia. Even though I would not be able to afford to print a life size one... it also is against Shapeways regulations to print weapons larger than 10cm!
