Re: What sailing knife do you use?
For everything I do in and around salt water, I love anything Spyderco makes in their H1 steel. It takes a fantastic edge, it never rusts, it's simple, and not expensive. And I'm a "knife geek."
I've carried one in the pocket of my lifeguard shorts, and given it no maintenance for a year now. Not a speck of rust on it. They're worth the price.
