If any of you have watched the Takumi no Sato (Village of Artisans) filler arc, you would know about the Fujaku Hishou Shouken (Weaklessness Soaring Short Swords). They had the ability to perform powerful Futon jutsu at minimal cost of chakra. I felt they were really powerful and their potential was wasted. Fujaku never seemed to have a Fuuton affinity. All she did was channel chakra into the blade and it converted it into Fuuton chakra and allowed her to perform powerful Fuuton Ninjutsu. Imagine if Naruto had it. His natural Fuuton affinity amplified by them. Imagine the possibilities. It would also keep true to his Uzumaki heritage. So what do you guys think. Were the swords wasted on the filler arc?
