It depends. Would they be left handed or right handed? Do they concealed carry? Is this sword for self defense or agressive attacks? Define what you mean by 'Zombies'. Will they wear kevlar rotting flesh? Why do you hate zombies so much? Are Zombies really like Bigfoot and the Loch Ness Monster: myth and legends? If so, they may require special steel. Do you need to attack them, or can you peacfully coexist? Have you exhausted all your other Zombie killing options, or wil this be your go to method? Will you have a neon green handle on the sword? I believe they only die from the neon green handled weapons. Why not just shoot them? Knife fighting is really not a good option. C'mon, have you ever heard of defending yourself with a sword? Only a shotgun will work, so long as it has neon green on it. Where will the sword be made? Only 'made in the USA' will work. Japan, China, European, nope. Won't work on US zombies. Which brings up an important point: how many Zombies sneek across the border from Canada daily due to our lax policies on border control. What are YOU going to do to fix the problem. Did you vote democrat last election? If so, the Zombies will take away your sword. That's what they do, and you caused it. So, which stars are Zombies? If a Zombie is hot, is it ok to do IT with her before you kill her? I mean, it's not like they can say no. Will the Zombies come from the East Coast or West? East coast and west coast Zombie music are TOTALLY different. Which also begs the question: What will be the soundtrack for the killing scene, and what type of boombox will you need to carry with you?
So I would say, depending on your answers, either might be ok.....
