I see no reason it works differently for different weapons aside from the obvious fact that the nature of attack determines the kind of damage being done. COA just amplifies whatever you use it with; it doesn't work differently for different users. If you use it with a sword, it cuts better and if you use it with a punch it hits harder.
Yeah, that's pretty much what I said in my previous quote to you. It was advanced COA but we were never given the confirmation about which level of COA it was but we later learned that Zoro doesn't have internal destruction but he still managed to damage Kaido which could only mean that it was a barrier armament which Zoro clearly posses.

lmao thanks man. This is one panel I needed the most to prove my point.
@HA001 I guess COA is not needed to not touch things.
Responding to your comment: If that were the COA's differential, Luffy would only need to put more strength in his punches, to overcome the durability of KAIDO, and this is not the case.
ODEN touched KAIDO during the cut, Ryou's definition is internal destruction without touching the user, there is a difference between a punch and a sword cut.
When KID says: can a punch work on KAIDO? This clearly shows that the normal COA is not enough, and the same applies to KILLER, who has a sharp weapon and introduces himself as an impressed person after Luffy's ACOA demonstration.
That's why the standard COA, the same COA that Luffy used there in 921, doesn't work.
KAIDO claimed that the sheaths would be using RYOU, more superficially, the sheaths needed to touch KAIDO to pierce it, this goes against the concept of not having to touch the user, as luffy demonstrated by punching that tree, there is a difference from Ryou (ACOA) in sword, and punch.
But by no means is the normal COA drilling KAIDO.
That is why ZORO used ACOA, KAIDO was cut by TATSUMAKI, Ryou luffy also caused damage to KAIDO, although superficial, in the same way that the sheaths also caused superficial damage.
