Pathetic cringe, that is not how the in universe characters will view it.
The scabbards did no damage, Zoro wounded Kaido but didn't put him down, but Luffy pummelled Kaido with G4 putting him down for several pages beforehand, none of the other supernovas did signifcant damage- Luffy was the only one confident that he was dealing damage, due to his internal destruction ryuo and superior physical stats.
Luffy on the other hand was boro breathed due to Big Mom's distraction, and earlier was exploded by Apoo's trick ability that knocked him out, and he doesn't have zoan regen, he was knocked out again by Kaido BEFORE LEARNING ADVANCED COC and reaching his peak strength.
Fresh Luffy with new COC peak strength would be more of a buff to current Luffy than restoring the amount of Damage Kaido has taken to him.
