I once had a set of disposable chopsticks that broke such that one of the sticks split longways for about 3/4's of it's length, and I effectively ended up with 1/2 and 1 & 1/2 chopsticks. I think that's the worst I've ever seen.

hmm i'm no expert at breaking them apart either ^_^

honestly, to get a split that bad, you pretty much need to be TRYING to do it like that.
