Yes, I remember them teaching us that in Boy Scouts; if no knife sheath is handy then just substitute your rectum.
“Maybe you could form some kind of rudimentary lathe…”
A rather disturbing person where I used to work showed us how you could turn an ordinary plastic credit card into a lethal slashing device by sharpening it. (If you had to disagree with Dave, it was a good idea to do so by phone, or with other more well-adjusted people in the room.)
Jawbone of a donkey? 
With all the use of chainsaws, I’m surprised you never see anyone using a pole pruner against zombies - so much better than having to get close to them.
I’d use Colt .45. It fires round, dull blades that fly through the air. Also, it’s very loud.
Failing that, the corkscrew on a swiss army knife must be useful for SOMETHING, right?
“Major Mountjoy-Standfast can’t out-think a bunch of gormless watchmen and civilians and some veterans with garden forks?” said Lord Venturi, who had no idea of how much damage a garden fork could do if hurled straight down from an elevation of twenty feet.
The messenger, who was a sub-lieutenant and very nervous, couldn’t find the right words to explain that “unarmed civilian” was stretching a point when it was a 200lb slaughterhouse man with a long hook in one hand and a flensing knife in the other.
This was, after all, the area of small traders, porters, butchers and longshoremen. And so standing in raggedy lines in front of Vimes were men who, every day, peacefully and legally, handled things with blades and spikes that made a mere sword look like a girl’s hatpin.
–Quotes by Terry Pratchett, Night Watch
“Some folks call it a Kaiser blade. I call it a sling blade, mmhmm…”
Ooh, glad you posted this. I had it in mind but had no idea what it was called.
Better than a spokeshave: I give you the drawknife. If you can get behind 'em, the perfect decapitation tool.
Ok, add: wood axe, fire axe, adze, hoe, mattock, pickaxe, flensing knife
No, actually I was thinking of an issue of DC’s Hell Blazer, where Constantine had to make a demoness magically invisible to the forces of Hell. He did it by carving a pentagram on her heart. To do this, he had to get to her heart; so he pulls out a surgical tool with a two-foot long curved serrated blade that’s smaller than a scythe but bigger than a sickle. No idea what the thing’s called.
Ooh, ooh! How about a notched mastic trowel?, or a linoleum knife, or a drywall hammer? Hey, how about a Peavey hook?
The garden tools I use are:
Hedge clippers
Lopping shears (short, thick blades)
Weedwacker
Lawnmower
Mattock
Hoe
Hula-Ho
Shovels
Bow rake (rigid teeth)
Brooms (supposedly not dangerous; but did you ever hit someone in the shin with a broom handle?)
150 feet of electric cord (good as a noose)
And remember the words of Sweet Brother Dick Whittington:
“It’s better to beat your swords into plowshares! You hit a man with a plowshare he’s gonna KNOW he’s been hit!”
ISTR that in The Faculty, the cutting arm off of a paper cutter such as this one was used as a weapon.
Ooh, I was gonna say that! My meager experience working on trail maintanence in a national park has taught me that those things can slice through soda cans with no trouble. Pulask axes, too - highly useful in all sorts of situations.
Thisice-axe look likes it could do a decent job against a zombie.
They wouldn’t be particularly practical, but if you’re specifically outfitting yourself to ward off a zombie invasion, these could be some fun footware to have around. And by that, I mean they could lead to the bloodiest fight scene ever.
Nail-clippers?
Actually, the Google links at the bottom of this thread are more than useful in this instance.
Obvious, obvious, obvious.
Lumpy. Make your hero a potter and use clay tools.
Perhaps the detached chain from a chain-saw could be used as a flail for a hand-held weapon or a bolo for a thrown weapon.
A hefty low-geared gasoline tiller would mangle someone nicely.
