First off, agreed that haki sucks, it's pure bullshit.
Second, we know Enma is a greedy sword, it takes all the haki it can get and more. Oden had Enma since he was 9 and grew to be a beast that he could freely pour his haki and be fine. Don't know if Enma can store haki but I can't dismiss it doesn't have residual haki from Oden since Kaido keeps bringing Oden up with Enma non-stop. It was also the only sword to cut Kaido in Zoro's dragon twister even though he used all three.
Third, saw a theory that the reason the Scabbard could cut Kaido his because they inherited Oden's will and willpower = haki or some shit like that so they have his haki. Reason why I don't want to dismiss this theory is because we know how close the Scabbards were with Oden and so when they inherited his will, they also got his haki that allowed them to cut Kaido's skin plus Kaido's comment. Haki sucks.
Oden wanted to beat Kaido and open Wano, I think after those are done we'll stop hearing about Oden's haki completely and Enma will be 100% Zoro's sword, probably a weaker version but Zoro will make it strong again with his own strength. It feels like Oda is going with Hero wants to beat Villian > Hero dies > Followers and swords gain his power > New Hero comes and is capable to wield sword > New Hero beats Villain > Hero rest.
