Place it at the cut where the sword is revealed, then follow with a metal pipe clang for the impact, and save the anime wow for the character reaction that follows the reveal.
O tym dźwięku
This is a very short katana sound effect, lasting under half a second, centered on a single sharp metallic slice. It feels sudden and tense, like a blade flashing past in a single moment, and it leaves a quick dramatic jolt rather than a lingering mood. Its brevity makes the impact feel clean and immediate, suited to a sudden reveal or a fast cut.
