1. Awl
   Bump cutter
2. Set square
   Plumb rule

A bump cutter looks a little bit like a giant squeegee, and in some ways, that's essentially what it is. It's a hand tool used in cement work for smoothing the cement in an area, ensuring an even and level surface when you're done.

1. Chisel
   Sledgehammer
2. Screwdriver

1. Jackhammer
   Power drill
2. Leveler
   Jack plane

Drills are some of the oldest tools in the world, far older than many people realize. Hand drills date back 35,000 years in China. Electric drills are actually quite a bit older than you might assume as well — the first one was patented in 1889.

1. Wood saw
   Hacksaw
2. Bow saw

Hacksaws are specifically designed for cutting metal as opposed to a regular handsaw intended for wood. Thanks to their versatility with blades that can be easily swapped in and out, you can cut any number of hard substances with a hacksaw, from plastic pipe to ceramic tiles.

1. Power wrench
   Cordless drill
2. Impact driver
   Adjustable spanner

An impact driver is different than a regular power drill or even a hammer drill insofar as it increases the power being delivered perpendicular to a screw or a bit. This means increased torque, like using a long wrench to loosen a bolt.

1. Siphon filter
   Planer
2. Adjustable spanner

1. Combination square
   Awl
2. Ladder
   Trestle

A ladder is an idea so simple it would likely be impossible to guess when and where it was first invented. It's worth noting, though, that there are 10,000-year-old cave paintings in Spain that depict them, so they're clearly very old.

Hand saws may seem a little old school and even antique, but they're pretty much invaluable. A power saw can be very useful, but a handsaw is so simple and quick to use to make a quick cut of wood you'd do well to make sure you have one in your toolbox.

1. T-square
   Float
2. Tape measure
   Spirit level

1. Reciprocating saw
   Coping saw
2. Jigsaw
   Sawzall

1. Planer
   Impact wrench
2. Nail gun
   Biscuit joiner

A nail gun is pretty much what the name implies — a device that uses the power of compressed air to shoot a nail into a surface. It works a lot faster and more effectively than just using a hammer and also works well in places where swinging a hammer just doesn't work.

1. Chainsaw
   Miter
2. Radial arm saw

1. Socket wrench
   Wire strippers
2. Adjustable wrench
   Needle nose piers

1. Putty knife
   Utility knife
2. Mason's knife
   Straight edge

Utility knives have a utilitarian sort of name because they're good for pretty much anything. Obviously, cutting open boxes is one of the primary uses, but any cutting will do. In many countries outside the United States, they're known as Stanley knives, named after Stanley Works, the company that manufactures them.

1. Skeleton gun
   Spirit level
2. Laser level
   Flashlight

Having a flashlight handy is never a bad idea for any number of construction jobs. The obvious would be any electrical work when there is no power for other lights, but of course, any work in basements, behind walls, under stairs, and in other dark places can benefit from a little light.

1. Gaffer tape
   Duct tape
2. Plumber's tape
   HVAC tape

Duct tape and duck tape are two commonly used names for the same product, and weirdly, both are correct. The original tape was made from something called cotton duck cloth, which is where the "duck" part comes from. It changed to "duct" sometime after WWII.

1. Stud finder
   Laser level
2. Oscillating multi-tool
   Pad sander

Stud finders are obviously meant to find wall studs, but they can do so in a variety of ways. Early stud finders used magnets in an attempt to find studs by locating the nails in them. The latest versions use a kind of radar to detect studs in walls.

1. Set square
   Scale pan
2. Wall chaser

1. Crescent wrench
   Basin wrench
2. Monkey wrench
   Torque wrench

A basin wrench or sink wrench is specially designed to be used on sinks or basins. The head pivots on the handle, allowing you to get into confined spaces to work, which, traditionally, you'd find under sinks where you can't fit a regular wrench.

1. Nail punches
   Wood chisels
2. Linesman set
   Socket set

A good socket set ensures that you'll always be able to find the right size socket for the job. A man named Pete Roberts sold the patent for the quick release socket set to Sears for $10,000, who believed the invention was nearly worthless before making a $44 million profit in 10 years.

1. Plumb bob
   Set square
2. Spirit level

1. Concrete mixer
   Wheelbarrow
2. End frame
   Head pan

A concrete mixer, as you might expect, mixes concrete. You pour the water, sand, stones, cement mix, and whatever else you might need into the barrel, and the mixer keeps it moving, so it blends but doesn't set.

1. Pickaxe
   Brick hammer
2. Chisel
   Mallet

1. Head pan
   Ball-peen hammer
2. Hard hat
   Bucket

Hard hats grew out of the tradition of dock workers putting tar on their heads and allowing it to cure in the sun to protect them from falling debris. Novelist Franz Kafka supposedly invented the modern version while working for the King of Bohemia.
