the journey of the sword...
Following what Triquetra said, the sword starts off on it's own all shiny and new, but it doesn't go far on its journey before it realizes it's not the only sword in the box, I mean, world! It's first challenge is another sword!
"Wait, we're like CLONES of each other! And we have the same powers!"
They fight, because after all, isn't the function of a sword to DO something, not just look all pretty and floaty up in the clouds! But they're evenly matched, they cannot accomplish anything by fighting. So instead, they remain "opposed" but not clashing. The fact they are at an angle, though, implies to me that they are still ready for action. They still haven't quite acceped the existence of the other, or the "others" right to exist.
