There is some wisdom in the talk about "Never rely on anything that needs charging, feeding, or sharpening". Only some. Frankly, I'm a believer in finding every advantage you can get, and technology is one of them.
Now a lot can be said about the utility of the humble claw hammer in an undead Apocalypse - it can be used as a small crowbar, nail up barricades, break heads without going dull, and can be found just about anywhere - often with ergonomic grips no less. However, most reanimates don't use ranged weapons, and are quite beyond a person in close combat - so melee weapons aren't that great in the first place, and blunt ones even worse - blunt trauma and knocking the brain around inside the skull works terrible wonders on humans - but doesn't really work on the buried vonrable parts of the reanimate - for that you want to remove or crush the head entirely. Either use and axe or sledge hammer - something that fits on a tool belt just isn't enough.
You should know by now, I am anything but an advocate for carrying around a lot of firepower. If
you look like you're expecting trouble, people are going to be more
than happy to oblige and all that. (Guns just make some people too jumpy
and others too overconfident - and when they meet - never a good
thing.) Still, I keep a Kalashnikov derived rifle with me (a model 101
in 5.56mm NATO to be exact - people ask all the time.) though I hardly
ever use it, and a hidden handgun too (.38 Super Colt 1911 derived
target model - I st - liberated both guns from a collector's basement
after the Event.)
Similarly - if you've got some plans - you don't need a big vehicle, or a lot of friends - but going alone and fast isn't for everyone.
