Questions for surfers :p

Hey guys, I have a project for design technology in school to make a bottle opener and for my target market, I chose people who enjoy the beach, surfing etc. I have compiled a list of questions for anyone who enjoys these things to answer about what they look for in a product like this.
1. What unique selling point would you be most looking for? By unique selling point, I mean something like a funky design or possibly a unique way to attach it to your shorts etc.
2. Do you mostly look at ergonomics (how the product interacts with the 5 senses, ie. how it feels in your hand), durability or design gimmick?
3. What stores would you go to, to buy a product like a bottle opener?
4. In what situation and where would you most likely need a bottle opener for?
5. What do you think bottle openers should have that they currently don't have as a standard?
I would really appreciate it if you could take the time to answer these few questions as it would really help my grade
P.S. Sorry if this type of thing isn't allowed in a surfing forum but I personally don't know any surfers so as I said, this would be of great help.
