Okay, a tuning fork actually looks like this:

Well, at the time of this writing, I still haven't tried tuning my guitar to a tuning fork. The truth is, I haven't seen anyone yet using this kind of tuning method. The local guitar stores doesn't seem to have this one on stock.
I did a little research over the Internet about how to use this thing. It's fairly simple once you are good at discerning pitches. A tuning fork only offers a single pitch tuning reference commonly known a the "A-440 Pitch".
