Generalities

• Choices of "best" or "important" tools indeed vary greatly -- this is typically because the lists depend upon whether the tools will be needed for handyman work indoors, for outdoor housework, for garden work, or for tinkering in the garage. So, a list of "most important" will be completely subjective and according to your specific needs. Having one basic toolbox is strongly encouraged by many builders as well as home owners.
  
  

Hammer and Pliers

  Every home needs a hammer. Nailing or pounding things together are tasks common to householders. Some lists have pliers as an important tool, and you'll find types from needle-nose to channel locks. An author for MSN Real Estate notes that locking pliers or vise grips are considered "the pit bull" in your toolbox.
  
  

Screwdriver and Wrench

  Though both of these come in sets or kits with varying sizes and styles, one good screwdriver and one good wrench are handy to keep in the house. The concern arises when you have to choose between a flat-head or Phillips-head (cross-head), and manual or electric screwdrivers. Wrenches are useful for plumbing problems and auto work. Another common recommendation is the Allen wrench -- also known as a hex-wrench or hex key. These come singly or in sets.
  
  

Prybar and Other Choices

• The prybar is handy and comes into play for many kinds of projects. Get one that is 12 to 15 inches long, and made of hexagonal rather than spring steel. Alternatives for the fifth most important tool depends on a number of factors, but reputable lists indicate a 25 foot measuring tape, an electric drill, a block plane, a level or a putty knife. Consider your needs when selecting any set of tools.
