If all you have is a hammer, every problem begins to look like a nail.
There are times when having a screwdriver or pair of pliers makes a complicated problem trivial.
Nobody asks contractors, carpenters, etc, "Why learn to use a screwdriver if i already have a hammer?". Really good contractors/carpenters have tons of tools and know how to use them well. All programmers should be doing the same thing, learning to use new tools and use them well.
But before we use any power tools, lets
take a moment to talk about shop safety. Be sure
to read, understand, and follow all the
safety rules that come with your power
tools. Doing so will greatly reduce
the risk of personal injury. And remember
this: there is no more important rule
than to wear these: safety glasses
