Let me start by addressing a couple of important questions- namely, are wands real, and do they work?
Well "yes" they are real and the use of a wand to help people focus, means that "yes" they can actually work. Forget the Harry Potter image of what wands do, wands focus an individuals energy!
Wands are personal things that are very much attuned to an individuals personal energy (for this reason lending or borrowing wands is an idea that often results in less powerful magic).
Wands can work, if you believe that they can help you then they will. They are even more powerful when you make them yourself!
