Hypothetically speaking, of course.
I always wondered that. If we had a zombie apocalypse, and there would be the kind of slow walkers (not the fast runners from Dawn of the Dead), would they really be as threatening as they appear in games like The Walking Dead? Sure, they still got the strength of a full grown human, but as they are slow and dumb, a sharp tool should take care of them... two machetes would be perfect though.
Even if it would be you vs. hundreds of them, as long as you don't get cornered you should be able to chop them down, one at a time. Or am I missing something? I just want to be well prepared :D
