Ok, as it seemed that the subject of Zoro's broken sword was a hot topic in the stickied chapter 426 discussion, I decided to make a thread dedicated to it. It's clear that Yubashiri is the sword that gets destoyed – You can tell by the hilt. So the only thing left to discuss is what sword he replaces it with.
Short term (till the end of the arc at least) I think that he'll use the cutlass he picked up on one of the Marines until he stumbles upon Funkfried. After the arc, i figure that they're going to have a chapter dedicated to him getting a new sword. As to what sword it is, well, we don't know. I thought that maybe he would pick up either the first or second generation demon splitter, but then I figured that Oda would probably go with an original model. Probably one of the 21 Oo-Wazamono (21 great works or something like that) like the Wadou Ichimonji is; at least I hope. I figure that one of the marine captains, lieutenants, or even the vice admirals has one that he's take. What do you all think?
