Large medieval swords like that(such as the claymore) were used for concussion damage. In medieval times, when armor was plenty and slicing was pretty much useless, they instead opted to smash the **** out of the enemy, causing internal damage and broken bones.

Either way, the sword you made that was linked, Elk, is not aerodynamic. The blade may be, which is hardly even there, but the rest of the sword is not. You've got twists and curls, and metal forming what looks like a tangled ball of hair, then the rest of the sword is made of chunky rock and such. Just because the blade itself is sharp doesn't mean the whole sword is aerodynamic.

Zideruic wins.
