Weapon / Tool
One of the more useful items to surviving through a zombie outbreak, large or small, will be your run-of-the-mill Crowbar. Now, some of you may be asking "A crowbar? That doesn't really seem right. It has neither the long range capability of a firearm nor is it some cool or exotic melee weapon like a sword."
Actually, a crowbar can serve as a life-saving option in a variety of ways. Firstly, the crowbar is available in a few different types ranging from iron up to titanium, all of them making it a very sturdy item that will last after an extended period of use; meaning you don't have to worry about replacing it regularly or having it fail in the middle of a fight. Secondly, if you should need another one, crowbars are extremely common, being a regular household tool, and could be found in your average town or city without difficulty. Lastly, a crowbar is easy to keep on you at all times whether your supplies or as a secondary weapon so it is there when you need it without an excess amount of weight or frustration.
As a weapon, the crowbar is useful for the times when you are forced to deal with a zombie at close range. While we always recommend dispatching the undead at a distance whenever possible, the crowbar is sturdy and heavy enough that a good swing or two can shatter a Zed head; or, with a little bit of practice and aim, the end of the bar can be used to puncture a zombie's eye and scramble their brain case.
Of course, a crowbar is a tool before it is a weapon. For this same reason, the presence of a crowbar can be exceedingly helpful in the you can utilize it for its original purpose. At camp or in the field, the crowbar can pry open stubborn doors, locks, and more. Likewise, if absolutely necessary, this same bar of metal can be used to block a door that might otherwise allow a flood of undead spill out against you; giving you precious minutes to save yourself.

Stay safe out there, Survivors.
