"Standard-issue kunai would do it if your control is good," Sasuke said thoughtfully, flipping one of his own kunai out and testing the balance of it with an absent toss. "You can recreate the slashing effect if you extend the shape of your own chakra until the last minute, then release it in an arc from the kunai.

"It's easier with lightning, but here," and he tossed the weapon an easy handful of metres away, lightning chakra crackling into visibility around his hand and travelling with the kunai, extending into a narrow thread of light before he let it break. The chakra coalesced briefly around the weapon, lightning easily conducting through the metal, then sparked apart in a wide arc.

It was no earth jutsu, but it was enough to char the dirt in every direction, and now that Sasuke was thinking about it ... if Tsunade could concentrate her lightning-natured chakra into raw physical strength, maybe it could be extended to distance as well --

But more immediately, he looked at Sakura, waiting for her response. He'd spent too many hours teaching jutsu to Naruto and Hinata not to look expectant now.
