I'm not precisely sure what you're supposed to do with this thing, but the experts at the Zombie Research Society say it's useful so I will take their word for it.

That might make the Zombie Apocalypse more fun, but what do I do with it in the meantime?

Just stick it in my garage? Whack weeds with it???

Presumably in the meantime, you should carry it around on your belt, never knowing how much warning you will get before the apocalypse.

It was originally designed so that truckers have a handy tool for cutting overcooked roadhouse waffles and murdering prostitutes, so you probably don't have much use for it in the short term.

Is this why restaurants no longer have names like "House of Waffles and Prostitutes"?

You're right that the apocalypse could come at any time, so it's best to be prepared.
