I will be taking a trip towards the end of summer to Hawaii, and will likely be doing a lot of snorkeling. I haven't done it since I was a kid, and am now wondering -- do I need/should I carry an EDC knife while in the water? I know that H1 steel would be a natural choice. However, I wanted to know if it's overkill to carry one? Also, if you do carry when snorkeling, what method do you use to carry? I'm guessing that IWB and pocket clip carry is probably not a secure method when swimming. Thanks for all your help and advice.
