User blog:123545/Zoro's new sword

Is it me or did zoro get a new sword after time skip? Is that one sword that zoro keeps holding( the one w/ the flower like cross guard on the sword) new or old? Because looking at his past swords the cross guard doesn't look like theirs. If it is just me, then is it shuusi or something like that( the sword he got from ryumma at thriller bark)?
