Consultants are experts (i.e. anybody from out of town) in a certain field - technician, DB pro, Agile coach, etc. The difference between a consultant and an [contract] employee, is usually, that consultants don't spend all of their time at the same place. So you can ignore the part about screw drivers and flashlights, if you won't ever have to bend over under the desk and behind that PC. You still need your tools, which may very well include flash drives, ebook-reader, laptop, portable disk, etc.
Hope this clears things...
