im 15 too. get a mora and a cheap hatchet or a billhook and a folding saw. then read for a few hours on this forum, then try battoning, feathersticks, chopping down a small tree and lots of other beginner things like that. then get yourself a firesteel and find an old cotton teatowel and a tin and make some charcloth. spend a couple of hours trying to get a flame from charcloth ember in various materials (to start with try thinly torn tissue papre and a few woodshavings). once you can do that easily try building a fire from that flame using your feathersticks and kindling you have chopped up. then you know how to get from ember to fire so try a firedrill (bow, stick and two blocks of wood, youtube it) and try getting that to work (much harder but can be made basically anywhere. then some other more advanced stuff like spoon and bowl making (get a couple of crook knives) and shelter building and within a year you will have spent loads on random bits of kit and be weaving crayfish traps and building birchbark canoes!
inspirational or what!
also, look at the knife laws. but basically for bushcraft all you need to know is you can have a knife if your parents buy you one (or 40 and counting in my case
). understanding parents are very useful in bushcraft or it can be hard to get going, and you need to be responsible and accept now that your going to get burnt and loose blood, but its part of the learning curve and a decent scar is a very good reminder of exactly what NOT to do (dont cut towards yourself if you want to keep your macaroni cheese down in my case!)
good luck!

you will find a lot of better quality and more expensive tools out there but that should get the ball rolling!
