Your replica is an overpriced piece of stainless steel that's going to break when it hits anything harder than a stalk of bamboo. And even if you do have a real sword, well, it won't do you any good against those guys with guns, no matter how good you are with it (and just looking at you, I can tell you're not good with it at all). And it's not a real magical sword made by Elves anyways. Because neither Elves nor magic exists!

Also, swords may not need to be reloaded, but they do need to be properly maintained in their own ways. If you don't want them to rust or lose sharpness, then you need to oil and sharpen them regularly.
