I'm 15 (I started on my own and getting small lessons from my farrier on basic blacksmithing no knives involved) and have made knives for a long while (or so it seems...about 2 or 3 yrs.) and i remember when i was that little guy saying "make me a sword" or "how do you make a sword". You have to keep in mind that kids that ask this aren't TRYING to be obnoxious. I completely agree with what you all say don't get me wrong! i preticularly like the quote made above "When someone comes up to me and says "Make me a sword!" I say "Sure hop up into the forge!" I've started with knives to learn how to heat treat and temper and have made several large knives that I have taken through XXXX and they dont crack, break, or loose their edge. I am now making an attempt at a short sword about 30 in. long. I'm not trying to brag and all I'm really getting at is: Anyone my age or younger that wants to bladesmith heed the advice above! Try and find someone who specializes in blades (not dissing my farrier who is quite good at it) and try and see if they are willing to teach you or find a blacksmiting guild and get contacts. You can't go from 'S' hooks to swords. Take your time and learn the basics.
Sorry to rant!
