In the fanfic, when Naruto coated his swords in Haki, it transformed his combat capabilities. Haki has different forms, like Armament Haki which can be used to harden the swords. This would mean his swords could withstand more force and deal more damage. His attacks would become more precise as well. Imagine Naruto facing a tough opponent. With Haki - coated swords, he could sense the opponent's weaknesses better. The Haki on the swords might also interact with his chakra in some unique ways, perhaps allowing him to transfer chakra through the Haki - coated blades for additional effects, like stunning an opponent on contact.
Coating his swords in Haki in the fanfic would change Naruto's combat abilities a great deal. Haki gives an extra layer of power. It could potentially make his swords more durable, so he doesn't have to worry about them breaking during intense battles. Also, it could add a new element to his fighting style. Since Naruto is known for his ninjutsu, adding swordsmanship with Haki - enhanced blades could make him a more versatile fighter. He could combine his Haki - powered sword strikes with his shadow clone jutsu, for instance, sending clones to attack while he uses the swords to fend off counterattacks.
