The sharp side is on the inside; so you require two motions for the same result, the second being extremely predictable and using the same blade, less likely to pierce armour. Also pole-arms are generally best used to keep space between you and your opponent because they're most deadly on their outer ends; not to invite them to get closer before striking, at which point the weapon can be trapped leaving you defenceless ;p

Removing the sectioning would be good. Another thing I'd have to ask would be one side being heavier because it carries the blade, so that it's limited as a bo-staff (it's perfect balance is what makes it so versatile, after all.)

Also working on posts. Should be up by tomorrow.
