Copper sword

Im not asking for a whole copper set, just the sword. It would make sense, since copper has been used for swords before. It wouldbe cool if the sword gets worse as it oxidizes, being able to remove the rust with a grindstone or a stone cutter and makingi it stay in good shape with honey. Also the sword would oxidize faster underwater and remove the wax by clicking a full cauldron or just holding it while under water. It would have 1point less damage than the iron sword (depending if you're on java or bedrock) and would lose 1point of damage everytime it oxidizes(max -3). Of course being crafted with 2 coppers and a stick. For a extra you could enchant it with channeling and get hit by a lightning bolt everytime you hit an entity. That's everything i could come up with my adhd
