Can anyone recommend a fixed blade knife for heavy saltwater use?

I’m looking for more of an EDC knife. I’ve been through many Civivi and Vosteed knives but they end up rusted real quick. I do live on an island and spend much of my time on the boat fishing and whatnot. I just purchased a Benchmade Mini Adira and am waiting on delivery, just wanted to see what else you could recommend on the fixed blade area. Thanks in advance!
