Attacking Momo with haki which Sanji blocks whioe grabbing Momo. The 1 ring is the middle part of King’s shin, and the second ring indicates the same sound that occurs when haki users clash.
Blocking again with his knee the second time and the black visual effects are again visible which means both use haki. The sound effect is a louder, more violent one suggesting Sanji yet again blocked King’s hakied up and fully powered up kick. He is expressing some discomfort but that’s to be expected holding onto Momo. Sanji is ina predicament having to shuffle Momo around
Again, King is looking like trash here. He wouldn’t have looked as bad if he would’ve used his sword to take down Big Chanter but no he actually kicked it down the waterfall. Sanji bested him here
So a shipwright squares equally with a swordsman, so wtf are you even arguing?
King is not a swordsman in as much as a karate black belt is a grappler. It’s secondary or even tertiary compared to devil fruit mastery
