In the Light Novel, Kirito uses the skill when he was fighting Heathcliff in Collinia (coloseum). The anime takes this skill out.

I do recall it being used (in the Light Novel) when Kirito is testing Dark Repulser with Elucidator in Warmth of the Heart (Lisbeth story).

And again, Light Novel, Kirito uses this to defeat Sterben AKA Death Gun in GGO.
