Even if I buy the most expensive raquet in the world, chances are I'm
not going to beat Pete Sampras, nor will I be able to beat Tiger with
the most costly clubs.

No doubt that is true, but it is an inappropriate comparison. You probably
couldn't even use Sampras' raquet or Woods' clubs. They are designed to be
used by experts with perfect form; a non-expert will find them very
unforgiving. After not skiing for a while I couldn't make a turn without
falling on my expert skis; had to go back to my softies to get my form back.

Professional woodworking tools are easier to use, more precise, do things
automatically that are difficult to do otherwise, and more durable. They
won't make an expert woodworker out of you, but they will sure help.
