Chainsaw

The Chainsaw is a new Close Combat weapon introduced in Left 4 Dead 2. It has not been seen in the beta footage as of yet.

It has unlimited uses, meaning that it can be very useful when the Survivors run out of ammo in a middle of a combat situation where it's too dangerous to use the pistols, such as hordes with a Hunter hiding somewhere among the Common Infected. and in too much danger to use the Pistols in critical such as Hordes with a Hunter inside of the horde and so. Like the other close combat weapons, it can kill every Common Infected in one hit, but it has its disadvantages as the Survivors cannot use any other weapons while carrying the close combat weapon, making it extremely dangerous when facing Special Infected, as it will take couple of seconds to throw it and run to help a pinned Survivor.

The Chainsaw is not really meant to be used against Special Infected; using it on a Boomer will spread the bile over the Survivors, against a Charger, Hunter and Smoker will take time for the Survivor to reach it, making it a dangerous situation, and against a Witch or a Tank will do little to no damage at all, so the chainsaw should only be used against Common Infected.
