Wanji is not Sanji.
Wanji is a 40 yo cook who now resides in All Blue after getting bored of his duels with Mihawk.
Because of the connection a chef has with his kitchen knives Wanji can infuse his with the ultimate Haki, one that Mihawk could never obtain.
Mihawk always carries on him the tiny blade that he used on Zoro in east blue, to remind himself that he could never defeat Wanji
