Do you think that a 12 year old very mature girl should have a pocket knife?

My friend is 12 and she is very very mature and she wants a pocket knife. I think it would be fine but she wants to know what other people would say. She has handled knives many times before and her parents are fine with her handling them on her own. She has even used kitchen knives to carve little spears out of sticks and says she wants a pocket knife for camping, fishing, and just for going outside because she likes to carve stuff out of sticks and likes to experiment with that kind of stuff. The only time she has ever gotten cut by a knife was when a knife fell through a picnic table and the point stuck in her toe but she said it only stung a tiny bit. She is very eye-hand coordinated and skilled with using her hands. She says she wants a swiss army knife.

So, would you say that it would be okay for her to have a swiss army pocket knife?

Thank you
