Baseball Bat

Pull out the ol' Louisville Slugger ladies and gentleman, it's time to crack some zombie skulls!

Everyone has extravagant ideas of guns and chainsaws, samurai swords and pipe bombs, those people are why we are hiding underground for so long. Unless you own an ammunition factory, and a few silencers, you're going to want to give up on your assault rifle Rambo. Of course, we do want guns around, we want lots of guns, we have to remember that zombies aren't our only possible enemy in this scenario, but as for the zombies themselves... It won't take long before they are trained better than your Labrador to come looking for food whenever they hear a loud bang.

It's probably a good idea to avoid sharp objects too, everyone likes the katana in our favorite zombie killing video game, but it takes YEARS to become trained to properly use that weapon, and you're more likely to hurt yourself than a zombie without said training. As far as axes and machetes go, they will get stuck in EVERYTHING you swing at, so it won't be effective at fighting off multiple targets at once.

As boring as it sounds, we're probably going to want to stick to blunt objects. Carry that hand cannon with you just in case, but shooting a gun should be paired with running away fast, because you just rang the dinner bell for a bunch of brain hungry, flesh eating dead folk.
