We were arguing about the durability. Stick to that and stop confusing your self.
Durability?
What the fuck is there to argue? Sanji is a panzy ass bitch who got his shin cracked by weak fuck like Vergo.
While Zoro shurgs off a strong hit from a Marine admiral that obliterates the ground producing impact as big as diced Mochi and it didn't just stop there, Fujitora stayed on him the entire time meaning same force was constantly crushing Zoro.
And not just that he had enough energy left to overpower Fujitora with just one blade, his weakest blade. That is a literal top tier durability feat, shrugging a semi serious attack from a top tier. Sanji would have been entirely crushed from bone to bone in that moment.
