Just from the looks of it you can tell this is no ordinary stick, oh no, this is the Stun Rod.
Resident Evil 5 features some pretty imposing weaponry, which kind of relegated the stun rod in the minds of many players. It's is kind of a shame because although it's a close quarters weapon like the knife, it has a shocking surprise that can deal a heck of a lot of damage.
I vividly remember using this instead of the knife when I ran out of ammo playing RE5, where it saved my skin on more than one occasion. Give it a shot (?) sometime, you won't regret it!
