Weapons, part 1.

Alright, weapons or skills, weapons or skills...?  Skill with weapons?  No.  Today is a weapons day.  'T's get started.

Wrenches:  Large or small, adjustable or fixed, heavy or... not quite as heavy, wrenches are hefty, effective weapons.  A good whack from a wrench can do a lot of damage.  Lighter wrenches may not have the cracking power of larger models, but you can throw them from high up for fantastic results.  As a bonus, you can dismantle about nine pieces of technology out of ten with an adjustable wrench and a screwdriver with a bit set.  However, wrenches are heavy and unwieldy.  You could do as much damage with more accuracy and less effort using a hatchet.  Wrenches also tend not to have "grippy" handles.  Some tools are made for swinging, so they get nice, shock-resistant grips.  Wrenches are designed to give you leverage when you're turning a nut or screw, and since they don't need grips to do that, they're not made with them.  You can wrap electrical or sports tape around the handle for a rough surface, but it won't be as good at absorbing the shock of a blow.  Generally, it's usually better to have a wrench in reserve than as your main weapon.  Still, if it's what you've got, use it how you like.

Shovels:  A bit tricky to place.  You certainly want them for construction-- building houses, walls, trenches, booby traps, that sort of thing-- but they really aren't made for combat.  If a zombie were coming at you, it wouldn't just slow down for you.  Hitting a fast, head-sized target takes practice and timing, and the shovel makes that job even more difficult by being overly heavy, awkward to grip, and, depending on the shovel, prone to breakage.  And the first swing, if it does connect, will probably just delay the zombie for a few seconds as it gets up from your attack.  On top of that, a shovel has a ridiculous delay between swings.  Even if you use the edge of the shovel, you have a very low chance of getting a kill.  It's incredibly useful, and you certainly want to bring one with you if you can, but mainly for building defenses and fortifications.
