Spiked Bat (Dead Rising 2)

The spiked bat is a combo weapon in Case Zero and Dead Rising 2 that is found in Still Creek and Fortune City. It is a baseball bat with nails sticking out of it, which can be made by combining a baseball bat and a box of nails. One of its attacks is hitting a zombie in the head with it, with the nails sticking into its forehead. After a few hits, the barrel of the bat will be soaked in blood.

Trivia
It is unknown how Chuck got some of the nails to stick sharp end out as they don't appear to be long enough to go through the baseball bat.
