It's not impossible that a carpenter or electrician might need some metal bent, but they generally wouldn't do it themselves. A plumber, on the other hand, will have a blowtorch in order to be able to bend smaller pipes by first softening them.

1. Carpenter; to turn on the big saws.
   Electrician; to turn off the mains electricity.
2. Plumber; to turn off the mains water.
   Plumber; to turn off the water in that room.

The stop cock key is used by a plumber to shut off water to the house itself. This means the plumber can work without the pipes leaking all over him and everything you own!

1. Plumber; a fish hooker.
   Electrician; a fish stick.
2. Carpenter; a wire threader.
   Someone else; a fabric puller.

Sometimes you need to find a cable in an area you cannot see into, or pull it through a space too small for your hands. This fish stick is designed to let you pull the cable where you cannot reach or see.

1. Supermeter
   Watt meter
2. Zapper
   Multimeter

The multimeter is better than the ordinardy volt meter. That's because it measures voltage, current and resistance all at once.

1. Cutter; an electrician
   Jigsaw; a carpenter
2. Slicer; a plumber
   Saw; a stonemason

This jigsaw is very useful if you are a carpenter. While stone masons do use saws, they could not get much out of this one, however, as it only goes through slim pieces of wood.

1. Bevel saw
   Curver
2. Router
   Hugger

This isn't the one you use to get onto the internet. This is what a carpenter uses to make the edges pretty on a table or other item.

This is a radiator key. It is designed to open the valve so that water can come out of your radiator. That means you can check levels and be sure that there is not an air bubble trapped in the pipes.

1. Electrican; spark meter
   Electrician; magic meter
2. Electrician; tick tester
   Plumber; current meter

This tick tester is also known as a glow meter or a sniffer. It detects electrical current in a circuit without you having to make any contact, which is much safer for many circuits.

1. Crusher; a plumber
   Holder; an elctrician
2. Vice; a carpenter
   Slider; someone else

Carpenters are not the only ones who use a vice, but they're the only ones in this question. Electricians and plumbers might use clamps to hold things in place.

1. Electrician; because you can't always turn all the circuits on and off until you find the right one!
   Plumber; because water and electricity do not mix.
2. Electrician; because they can't work on a circuit that is on.
   Someone else; for reasons unknown.

It's easy to turn all your own circuit breakers off until you isolate the right one, but you can't do that in an office building. This device helps you figure out which one isn't working without making potentially hundreds of people mad at you!

1. Someone else; a jack
   Carpenter; a crusher
2. Carpenter; a raiser
   Electrician; a hoist

This is a jack, and mechanics use it to raise your car so they can get at the underside or change a tire. It's not for electricians, plumbers or carpenters!

This is a tone generator. It serves a similar purpose to a voltage detector, but instead of lighting up it makes a sound. If you have an electronic keyboard, it probably has similar insides!

1. Electrician; a deburrer
   Plumber; a deburrer
2. Carpenter; a deburrer
   Plumber; a smoothener

This device is called a deburrer. It's designed to smooth out the surface of metal objects. Deburring is a major cost in manufacturing, and if your pipes are not properly deburred, you will get blockages all the time.

1. Carpenter; a hammerback
   Plumber; a pipe puller
2. Carpenter; a nail puller
   Electrician; plug puller

This clawed-looking device is for pulling nails out of things. Most hammers have one on the other side of the head from the side you used to knock in the nail in the first place!

This is actually not a carpenter's tool, though it looks like one as it is a saw. A reciprocating saw is largely used to cut conduit, which as we've seen is used to trail cables or bundles of cables around buildings.

This is a plunger, of course - we're giving you an easy one to reward you for your performance so far! A plumber uses this to break up and dislodge basic blockages. It's something you should own and know how to use, as it will spare you a lot of misery.

1. Plumber; because it is rust resistant.
   Carpenter; because it can double as a chisel.
2. Electrician; because it is insulated.
   Someone else; because it looks cool.

The main occupational hazard for an electrician is being zapped. This handy screwdriver has a little outfit on that saves its owner from that fate.

1. Electrician; a reamer
   Plumber; a chopper
2. Electrician; a cutter
   Someone else; a zagger

There are tubes in your building that carry electrical wires about the place, called conduit. If you cut them with regular tools, you can end up with jagged and thus dangerous edges. A reamer will ensure this doesn't happen.

1. Carpenter; a plumb line
   Electrican; a ballstring
2. Plumber; a nutstring
   Someone else; it has no name.

This is the ultimate tool in carpentry! You can make one yourself and use it to test whether your vertical lines are on the square or not.

1. Carpenter; a wallhammer
   Stonemason; a sledgehammer
2. Carpenter; woodhammer
   Plumber; a pipebuster

This is not for carpenters, electricians or plumbers. It's for someone else; a stonemason or other type of craftsman who needs to take out a section of wall. He may well be working with all the others, though!

1. Plumber; two point laser
   Electrician; two point laser
2. Carpenter; Darth Maul laser
   Someone else; super laser

This is a great device to help you figure out where to put say, a light fixture, when you can't mark up the ceiling easily. You map it on the floor and use the laser to show you where to put your circuitry.

This is four-post hoist and you use it to lift up a car. It's thus used by a mechanic, not a plumber, electrician or carpenter.

1. Carpenter; a lathe
   Plumber: an unclogger
2. Electrician; a sparker
   Carpenter; a smoother

A lathe is used to smooth the surface once your item is finished and ready to be varnished or painted. It takes the rough parts off with more vehemence than sanding and more precision than sawing.

1. Plumber: pipe split
   Electrician; roto split
2. Cartpenter; wood split
   Someone else; metal split

This highly speicalized device is used for stripping wires that have a metallic casing. You cannot simply clip their casing safely, and the roto split will help you do it.

This is a pipe bender. It's used for when the pre-made pipe sections don't fit, and you need to curve or straighten them just a little to get them in.

1. Carpenter; a woodener
   Plumber; a snake
2. Plumber; a wriggler
   Plumber; an unclogger

This serves a similar purpose to our carpenter's fish sticks from earlier. It's about being able to apply pressure and reach where you cannot see.

Carpenters often mark in chalk before they cut. This way they don't have to make a permanent mark or risk losing sight of the right spot.

1. Red tape
   Fish tape
2. Sticky tape
   Gaff tape

This is a lot like our fish stick from earlier; it's used to get wires through tricky holes. The difference is that it can be very long and comes on a wheel to keep it neat.
