It seems we need much more detail, like usetime, knockback, and such to see if it would be extremely powerful or not. It *seems* like a broadsword, which doesn't make too much sense, as the Pirates already drop a Cutlass and the Shadow Chests are prehardmode, making it either OP or UP depending on what it's balanced for. Coming Shadow Chests would also make it irrelevant since Night's Edge is so close to the tier and you have the hardmode ore swords right after it, along with the Breaker Blade around the same time, not to mention the fact that you won't even encounter one in a shadow chest half the time. It also just doesn't really fit the theme of, well anything. Pirates nor Hell are very likely to contain French Fries, let alone one that functions as an oddly powerful weapon (As in the fact that hitting someone once with it will do comparable damage to chlorophyte broadswords, not talking about its balance since we don't know the usetime)
