I dunno about everyone else, but I think this is all on the level. Obvoiusly yoo're a smart girl based on your replies on this thread alone. You also show signs on your site of someone who is just getting into the biz, knife selection, pricing, site layout (nice and neat btw). I like it, and wish you all the best. It's very cool to see anyone with that kind of initiative and smarts to pull this operation together and get it going at 15! (Nonetheless a girl, which is even a bit cooler, and not in a creepy way, just a refreshingly different way!)
There was a local knife shop for a while in my area that was owned and run by an amazing woman (ok, she was hot, too) who really knew her shiz, and carried top notch stuff. Proof enough for me that this can be done, especially by a tech saavy young lady such as yourself!
Hand around her and the other forums to keep in touch with the industry trends on what sells, and CAREFULLY listen to the GOOD advice (ignore the aholes that linger as well), and you'll do great!
