I don't know, Toriko wasn't really all that strong at this point, end of pre-timeskip Zoro actually was probably stronger when it came to cutting attacks. Plus he has a whole hour to do it, I think he could pull it off with difficulty of course. Post-time skip Zoro might be able to do it, CL 80-99 creatures honestly? Not even one of them was town level in DC (the power gap once creatures get 100+ is insane), and an 85 was able to cut the corn, Zoro Post-timeskip is probably town level, but we haven't seen him go all out yet, so I'm a bit hesitant to say he does it with ease, he was able to cut through a Pacifista pretty easily though
@YoungChief: you seem to forget that getting though death falls (which creates a mushroom cloud almost the size of the everest) is one of the conditions to get to the shining gourami which was lvl 80. death falls is way above town level. and hanya panda had the strenght to put gourmet casino toriko in trouble (even though toriko bested death falls with his 36 ren kugi).
toriko said the baby BB corn was as hard as a GT robo. i like to compare GT robos to pacifistas as both are harder than steel and made of alloys.
@othus12: I know, but Zoro didn't even have to try when cutting the Pacifista, given an hour I'm sure he could manage against the BB Corn.
Pre timeskip zoro swords cant do anything against the BB corn, Post time skip cuts it with a lot of difficulty
So basically this ^
