A cordless drill
No doubt about it. I bought a DeWalt 14.4V three years ago, and it's been invaluable to me. alt text http://www.homedepot.com/catalog/productImages/300/34/34c4b1f5-f4c7-465c-b9bb-f0a9ba2cd2ef_300.jpg

A good weight crowbar
Use it for lifting, prying, removing, bashing, demolishing and most importantly, against zombies and headcrabs.

Utility Knife

For about $10-15 USD you can get 100 utility knife blades, so you don't have to worry about sharpening your knife/breaking the blade (except your eyes of course!).

I use mine for all sorts of stuff.

A power miter saw (compound if possible).

It will cut anything you'd cut with a circular saw (other than large sheets), and you'll also be able to cut any trim pieces you'll ever need. Adding and replacing trim is a relatively easy thing to do and can quickly add value and better the appearance of a house. Few things come as close the a bang-for-the-buck arena.

Non-Contact Voltage Tester.
This comes in very handy to make sure you turned off the correct circuit breaker before doing any electrical work. And really helps if you have some funky wiring in your house and not everything in a single box is on the same circuit.

Screwdriver set

screwdrivers http://img339.imageshack.us/img339/7803/31032044.jpg

Your exact types will differ by country, but you likely want:

  • Slot-head (2 or 3 sizes)
  • Phillips (atleast size #3, maybe #2 and #4)
  • Robertson (atleast red, green, and black)

Rubber handles will save your hands after a bit of use. Also, try to find black tipped drivers, as this means they're hardened and shouldn't wear down as quickly.

A reciprocating saw (a.ka. sawzall) -

  1. Makes short work of any tearout job.
  2. Gets into places that other saws can't.
  3. Great stand-in for a chainsaw outside (for small stuff)

Fire extingusher

http://a.imageshack.us/img291/47/firekz.jpg

I have something similar to this Kiddie Single-use from Home Depot because of its ABC rating:

Suitable for use on Class A (trash, wood, & paper), Class B (liquids & gases) and Class C fires (energized electrical equipment). The Full Home unit is fitted with a pressure gauge that provides at-a-glance status, is manufactured from lightwieght aluminum and a tough nylon valve assembly.

  • Mult-Purpose Dry Chemical
  • UL Listed / Rated 1-A, 10-B:C
  • Suitable for use on most common fires

Better to have it and not need it!

I'm surprised no one has mentioned them but I think a good set of chisels are invaluable. Any time you're working with wood, a sharp set of chisels can be the key to getting a good fit and finish.

Safety Glasses

alt text

Not really a "tool" per se, but one thing I ALWAYS and is stress ALWAYS make sure I have in my tool box and wear all the time.

Had a friend that got metal in his eye and had to have the metal drilled out, creeped me out so much that I now wear safety glasses anytime I do any kind of work around the house.

A small pancake compressor. You can easily borrow / rent the tools, but having the compressor for so many jobs comes in handy. Can also be used without a tool to blow stuff off, fill tires, etc.

A Good Multi-tool

enter image description here

My personal favourite tool was my Gerber - though I know some people also like/prefer Leathermans. This is one thing where going cheap is not worth it. Anything Gerber, -Leatherman, -SOG, or any other quality tool brand really shines when compared with a cheap $10 variety. Seriously - save up for a few months and buy a good one. You'll be very glad you did.

I used mine almost daily until I lost it :'(

I'm saving up for a new one :D

A ratchet with a gator-grip head. That is, unless unlike myself, you really like digging through a toolbox full of sockets for every job and can't identify the sizes on sight.

BTW: I have no interest in the company that makes Gator-grip, I just didn't know the generic name for this type of tool (if there is one).

I love Japanese saws. They cut on the pull stroke and leaves a very narrow kerf (the channel that it cuts). I find that it cuts through wood a lot easier. Cutting on the pull stroke means that the blade won't bend. For saws that cut on the push stroke (most western saws), the blade might bend as you push.

I have this all purpose one, Japanese Modern Ryoba Saw, at home. One side is for ripping (cutting to a certain width) the other is for cross cutting (cutting to a certain length)

A straight edge is really important. I actually have a 48" long aluminum ruler/straight edge that has a significant depth. It's great for drawing long lines and I sometimes use it as a guide for a circular saw or router.

Lineman's Pliers

Lineman's pliers are a sort of heavy duty combination of wire-cutter and pliers. A pair of lineman's pliers accompanied by a pair of wire strippers is about all you need to do just about any home wiring project. I've also used it to pull out staples and nails, bend sheetmetal, cut open tubes of silicon, and even as a light-duty makeshift hammer when I didn't want to walk all the way back to the garage.

A hammer drill

Something you'll definitely want if you're doing any kind of drilling into masonry or stone. A bonus is that these can typically be used as just a regular drill by turning off the hammering action, so it's basically a 2-in-1 tool. Some even let you turn off the drilling action so you can use it like a small jackhammer.

Workbench with a Vice

This may not count as a "tool", but not having one can make DIY projects difficult. I don't have one, and trying to sharpen a mower blade on your kitchen table is sub-optimal. Then there was the metal bracket I needed to drill a hole into... holding it with my hand...

I've had my eye on this bench from Home Depot. I like the steel work surface. I will need to drill holes to bolt the vice to the top, though.

alt text http://www.homedepot.com/catalog/productImages/300/82/82549c7e-6099-4381-84be-7b72a7c3afd4_300.jpg

Update: Last weekend, I bought this bench along with a 6" vice. My dad and I assembled it as a weekend project. We drilled holes for the vice and secured it with 1/2" bolts. Overall I am pleased with it. It did require a drill for assembly, which was a little unexpected. Here are the photos. (Sorry for the poor lighting, a good workshop light is next on my list!)

Cordless Impact Driver

alt text http://www.lcdpayless.com/images/ryobi/RyobiOnePlusImpactDriver1.jpg

The ultimate compliment to your cordless drill - it does everything my cordless drill sucked at doing!

  1. Drives in screws without mangling the fastener head (phillips head screws anyone?)
  2. Removes rusted/stuck items like you wouldn't believe (Read: no rounded out screws or rounded off nuts/bolts)
  3. Cordless Drill will not drive a 3" screw into a stud - Impact Driver doesn't break a sweat.
  4. Compared with cordless drill, much less torque transferred to your wrist makes it more comfortable to operate

A Picquic.

enter image description here

[I would have left this as a comment on the screwdriver-set answer, but I don't have sufficient rep.]

If you're in Canada, the one tool I'd recommend above any other is the standard Picquic combination screwdriver. Canadian Tire's page is probably the best example -- judging by the reviews, I'm not the only one who loves it. :)

I've used mine for years, on almost every job I've done around the house. In a pinch, the bits also fit well into a cordless drill. There are probably good equivalents in other countries, though I've not run across any myself.
