Nightstick

"♪ Gonna beat me a zombie to death with a nightstick~♪"

- Ellis The Nightstick is a close combat weapon, introduced in Left 4 Dead 2. It is only found in The Parish campaign, which are dropped by the Riot Infected.

The Nightstick is classified as a Bludgeoning weapon, and will spew blood, but will never dismantle the Infected.

Pros

 * Has the fastest attack rate of all melee weapons (except chainsaw).
 * Can be randomly dropped by defeated Riot Infected.

Cons

 * Has an incredibly small arc of swing
 * Poor hit registration on Infected
 * Odd animation for swing means that it's hard to tell if you have scored a hit

Console Command
There is only one console command for the Nightstick:
 * sv_infected_riot_control_tonfa_probability XX (where XX is a percentage written in a tens decimal form)

The code above will determine the probability for the Nightstick to spawn in dead Riot Infected. It is written in a tens decimal form. So the default is "0.1" it will have the probability of 10%, therefore, when the player inputs "1" (signified as 100%), every dead Riot Infected would always spawn a Nightstick.
