The Perfect Zombie Weapon

Admit it, you had thoughts about the perfect zombie apocalypse weapons. I know, you would have more then one. But play along, if you could have just one. What would it be?

Guns: Guns are cool. but they are loud and eventually you will run out of ammo.

Sword/Machete: Good choice. You can go a long way if you know how to use one but you to have to be close to the zombie.

Chainsaw: Lets be real, it would be fun buy totally unrealistic.

Fixed blade knife: This would be my second choice. I just do not like the fact that I need to get too close to the zombie.

Ok, my go to weapons in the zombie apocalypse would be a spear. A four to five foot shaft and up to two foot blade. A spear would give you the distance you need and it will never run dry.
