Im 17 right now, and have been going to blade show since I was 15. I went yesterday, and I didnt have anybody talk down to me or act as if I was inferior, even when I asked to see Medfords and Hobacks and the like. Nobody treated me like id never be able to afford the customs i looked at even though we both knew that was the case. I wasnt walking around spewing random knife facts out trying to impress people, but if I knew the name of the knife I wanted to look at id use the name, or if I had a specific question id use some knife "terminology". There's thousands of like-minded people in one room, all sharing in the same hobby. Nobody treated me like an outsider. I was talked to like I was just another knife guy. You'll be fine!
