Hakirite

Hakirite, the Leaf Cutter, is Ryusuke Sanada's signature weapon; A black gripped Katana with a simple oval-shaped pommel made of steel. The cross guard of the sword was a steel black with a design of a serpentine dragon coiling around the blade present. The blade was made of reinforced metals to increase its durability and the central ridge was adorned with the blade's signature blue light, an odd material that began to glow when it interacted with Chakra - such as through Chakra Flow. The scabbard was a simple black with the same blue light on its lower end, however it was in less of a flowing design than on the blade - being a single straight line.

Hand crafted by Ryusuke Sanada himself, Hakirite, replaced Ryusuke's old katana as his main weapon. Ryusuke developed his Kenjutsu techniques around using this weapon and it eventually became symbolic of him. Attributed to Konoha's Blue Lightning for the blue light that it produced. The reinforced metals used in its construction make it stronger than regular blades but not so far as to become immune to being damaged. It is simply harder to damage than the regular katana but this increase in durability also required an increase in the blade's mass making it a heavier weapon, and thus harder to swing than other Katana.
