First, you said that the blades are 4' in total, and now the scabbards are at 2'? What does not make sense now is the length from the pommel to the base of the blades, where the sword "sits" at the mouth of the scabbard. With that definiton of length for a scabbard, a 3-foot sword is ideal, but is much too short for 4' swords.

Anyways, here is proof from the Light Novel that neither sword should be more than 4' long. So, prepare to be spoiled.
