OFFICIAL TIERLIST OF WEAPONS THAT WOULDN'T SUCK DICK IN THE ZOMBIE APOCALYPSE:

Weapons will be ranked on 2 things.
1. How viable they are to kill a group of zombies, as a single zombie poses negligible threat to anyone who isn't already going to die at that point.
2. The amount of effort, training or other factors needed to use the weapon effectively. This list assumes all weapons can be cleaned and maintained properly.

S Rank:
>Mace
>Broadsword
>Bilhook
>Axe
>Hammer
All items can be used effectively with little to no training or familiarity and can be used effectively in cramped conditions.
A rank:
>Guns* (caveat of them being useless without ammo and attracting more zombies)
>Halberd
>Spear
>Zweihander
>Bow and arrow
>Crossbow
All items are effective but require additional items to work, or training to operate. Some items are not suitable for confined spaces
B rank:
>Dagger
>Sling
>Explosives
>Pike
>Artillery
Situational use at best
C rank:
>Flamethrowers
>Anything that requires a certain method for proper use, such as Katanas or fencing rapiers
Impractical, especially if you don't know how to use it. Your Katan might be sharp but blood loss ain't doing shit to a zombie.
If you disagree you're a faggot.
