Wooden ninja tools were not as sturdy as real ones, nor were they as heavy.
Aside from interference from the environment, controlling one's strength had to be extremely precise. As with Mirai's demonstration, striking targets in different directions at the same time was even more difficult.
Mirai naturally heard his low voice. He was not surprised that Kakashi had noticed it.
Mirai smiled and turned sideways to look at the awestruck youths. "The key to practicing kunai techniques lies in controlling your strength and movements, just as I said before. Without that control, there's no point in making everyone persist in training and endure hardship. If you handle it properly, stones work just as well."

With a slight exertion of force, he threw the stones at several wooden stakes.
However, in everyone's eyes, the result this time was merely several stones striking several wooden stakes. The visual impact was nowhere near as powerful as Mirai's earlier kunai throw.
Kakashi was the only one staring intently at the wooden stakes struck by the stones.
Bzzz—
The stakes trembled slightly. Then, at a certain moment, the kunai on the topmost guideline of the stakes fell straight down.
