Pickaxe

A pickaxe is a tool designed for digging, but let's face it... it's best used to dispatch someone who has thoroughly pissed you off. A pickaxe is distinguished from other types of axes by the fact that one end of the head is a sharpened point, while the other is blunt. Boring people use these for agricultural purposes or for mining, but those who really know their stuff recognize it as an effective, if albeit clumsy, tool for vanquishing zombies. One solid blow to the back of the melon will make just about any zombie drop like a bag of apples.

In fiction
The effectiveness of a pickaxe was most memorably demonstrated in the 1985 black comedy film The Return of the Living Dead. Two morgue attendants, Burt and Freddy find themselves in the unenviable positition of watching their subjects rise from the tables to attack them. When a crazy naked zombie lunged at Burt, Freddy whacked him through the back of the head with the pickaxe.

A pickaxe was also used in the "Pretty Much Dead Already" episode of AMC's The Walking Dead.
