I am looking for suggestions on a good knife for use in, and around, water. I would like to find a knife I can keep on me (preferably IWB, but around my neck also an option) at the beach or while rafting and wet-wading while fishing. I would really like a folder, but my main concern is getting sand in the pivot. A short fixed-blade knife would probably also work. I have looked at Gerber's River Shorty and River Runner and was unimpressed. I'm also obviously concerned about corrosion too. From what I have gathered on these forums, it looks like a Spyderco Salt would be a great option, but I'm looking for other solutions as well. Any thoughts would be welcome. Thanks!
