Kassau Busterblade

An unfathomably enormous blade bigger and heavier than most can imagine, much wider and heavier of a blade than standard greatswords. Many argue they are far too big to even be called swords - too big, too heavy, and too rough, made out of solid wrought iron roughly pounded into shape to barely resemble a blade - only their creators, the vicious barbarian tribes of the Kassau Matriarchy, can wield them properly.   As an unexpected side benefit, the blade's titanic mass lends itself extremely well to being used for maneuvers and for shielding one's body, as the bigger versions of the Busterblade are wide enough to completely guard one's torso, head, neck, and legs with little issue - granting a shield bonus that varies in size depending on the mass and width of the Busterblade(See Cost and Special, above).   Wielding a Buster Blade grants a +2 bonus per +1 Shield Bonus the weapon proves on all bull rush and overrun(not trample) maneuvers and a +1 bonus per on reposition maneuvers, and while wielding a Busterblade you can ignore the Size prerequisite on the Awesome Blow Monster Feat(And gain a +2 bonus on on all awesome blow maneuver checks per +1 shield bonus the weapon grants).  

At the GM's Discretion, a +2 or greater Busterblade could feasibly give partial cover when planted or otherwise used as a dedicated cover item. Likewise, a +4 or greater Busterblade might give full cover when used identically - at GM's discretion.
