Is there a legal age to purchase a knife in America?

Question

I'm 16 and yet I don't know if you have to be 18 or if there even is a legal age to purchase a knife. There seems to be nothing on the internet concerning this issue.

Answer 1

varies by county and state; call your sheriff's department

Answer 2

I don't think so but its probably a function of the municipality you live in. I got my first knife, a cheap hunting knife, at a fireman's bazaar when I was ten and I've had them ever since. Shucks when I was a kid no one even worried about a kid carrying one to school. I always had a Swiss Army knife in my pocket in elementary school.
