>> i want to buy a balisong but my dad does not know why i should get one if there is no use for it
If your 15 years old, then your Dad should have started to teach you 3 years ago, how to handle a knife. It's obvious that your a rich city kid, who can afford to hire people to cut your grass, butcher your food and make your clothing. Even build your house.
Still rich kid or not, everyone should learn how to use a knife and they should learn some of the basic survival skills. A Balisong is as good as any knife to begin with, because in the closed position it is safe to carry. Unlike a kitchen knife that is dangerous to carry. If a parent does not buy a knife for their kids, usually they will be playing with the kitchen knives.
When teenagers master the use of a simple cutting tool, then they can move onto more complex and vastly more dangerous cutting instrament like power saws and so forth. I know a 16 year old who last a finger to a power saw, because he was moved into it to fast, and they did not teach him proper respect. In fact, I know a lot of people who have lost a finger or even fingers.
So, it's best to start off with a simple tool like a Balisong or any other pocket knife, then move into fixed blades with a sheath,and from there onto more complex tools when the parent feels that the teenager can handle it without hurting themselves.
My wife could handle any sort of knife by the second grade. But she comes from a poor family and they could not always afford to hire someone to do there work for them. Thanks, JohnR7
