A shotgun, on the other hand, does end up being useful because of the huge impact spread all throughout, possible causing the zombies body to fall apart to uselessness.
So much hinges on the nature of the zombies!
The only problem with trying for decapitations in melee is you really need to get inside their guard, you need to be VERY accurate to hit the neck, and you need to hit it with a ton of force, especially with as short a blade as you find on a machete. Maybe if you could get your hands on a claymore it would work. That's another reason I was going for an impromptu warhammer instead - I just have to hit the head rather than catch the neck and sever the spine, and it's much easier to pull free.
I suggest the Mighty Kilij, Weighted tip so when swinging its going to cut right through anything it hits. also Used by Vlad the Impaler, clearly nothing cooler. Wanna see what it can do? google kilij deadliest warrior.
The problem I see with the Kilij is that it's still a cutting/thrusting weapon, which would only be effective against RAGE-style zombies. Against undead, you really need something more likely to flat-out either destroy or remove the head.
And don't read too much into the weapons used by unbeaten warriors: Yes, Vlad used a Kilij. However, Miyamoto Musashi never lost with either katana or bokken, and William Marshal defeated over 500 knights over the course of his career, mostly using lance, bastard sword, and mace.

Katana looks cool and all but... no... just no... to much upkeep and severing the spine would blunt it to ineffective very quickly. Also it only has one cutting surface so you would have to redirect the angle every stroke. Also to be effective you would have to keep your arms horizontal a lot which would tire you out faster.
Guns pretty much also a no.. not only do you run out of ammo and are loud thereby drawing the attention of more zombies but also in real world situations it has been shown police have about an 11% hit rate so 9/10ths of your shots would miss... and thats just aiming at a whole person not something the size of a canalope also thats people(the police) who are trained and have an average of 95% rate in target shooting. Panic, adrenaline and increased heart rate will throw off shots.
Bats are kind of inefficient since there is a pretty good chance that it would not break open the skull on the first hit. Unless perhaps you hit them with all your might gut then again you would tire yourself out relatively quickly.
Crowbars are to heavy for extended use as well. They are also slow so you would be overwhelmed a lot quicker.
Personally I would choose a riot shield and a Mace. Something with Spikes to concentrate the force of the blow to break apart the skull easier. Also a Mace is only 3lbs or so and gives you better reach than a hammer and you don't have to pay attention to which way it is facing. It also uses an up and down motion for the most part. Which is a lot easier to do then the side to side you would have to do with a sword. Riot shield would be used for pushing back and giving yourself breathing room if there were more than one.
You have 2 categories of katana's:
1. the ones you can afford and are dull, of bad steel that will break or bend on you, and that look shiny but are utter crap.
2. the ones you can not afford and are incredible weapons that require a ton of maintenance of which you usually have no clue in the first place.
And than there is the Cold Steel 2 handed katana:
basically a machete in a katana form. Strong, durable in rather good steel. And most of all: dead cheap.
Only issue: you might have to resharpen the edge, so some knowledge is required. As with any blade.
I hate advertising for any one company, but as far as the sillyness of this tread goes: that one...
And if on a slightly bigger budget, the warrior series.
So much for the fun.
Now for the real stuff. Since zombies aren't that common in real life, this is all a fun and hypotethical 'what if' tread.
Do NOT get these things as toys! They are not toys and will surely put you in the hospital if you goof around with them.
Only order one if you see a zombie, just make sure to ask for express delivery
Do you guys hear yourself speaking?? Seariously!!
The only thing what would happen i f you buy a katana sword is that reality hits you and you realise you just trew away lots of money. wich you could have used to buy more beer!
I'm no rockstar .., i'm a fucking legend!!

Very, very easy to make. Recipe can be found on your fave search engine.
Any weapon that requires on muscle power for it's killing force will be of limited usefulness in something like a Zombie Apocalypse. How long do you think you can keep swinging a sword, or a baseball bat, or a knife, or firing arrows? A few hours and you'll be completely exhausted.
Weapons relying on muscle power also require physical space to operate, but also require close contact to inflict harm. A man with a sword can be overwhelmed by unarmed opponents. Realistically, you might kill a few dozen and then you're toast.
Ppl watch to much anime/games where the protaganist cuts ppl/zombies as if they were paper
If you want a Katana, then you should ask Sephiroth
