IMO, the tomahawk is a poor choice. The spike end could easily get caught. The machete is a better choice. I would have to choose one of these shovels and most definitely this crowbar.

You'll be breaking and entering a lot of places, so you'll need a good tool to get past doors and windows. And you don't want something too heavy to swing. The FuBar is ~8lbs, might be too hard to swing (or at least swing enough for a kill), so the shovel will come in handy for that. The serrated or sharp edge is perfect for cutting through shit.
