I know it is a folder, but it makes an excellent dive knife: a Spyderco Pacific Salt, Atlantic, Salt, or Salt 1. Read this: (it is from TazKristi of Spyderco: "Here's a couple of real-world examples...
There is a writer for Sea Kayak magazine who received samples of the Salt Series for an article he was writing. He admitted that he was very skeptical of any company's claims of a guarantee (we guarantee the Salt Series knives will NOT rust). His office sits on a pier near Seattle, so he promptly took a couple of mason jars down to the pier, filled them with sea water, put the knives in and sealed the jars. He tried for a couple of months to get those knives to rust. I believe he is in fact still trying, we hear from him every so often and he is continually amazed that he can't make them rust.
Also, the Salt Series knives are used heavily by an account of mine that supplies deap sea divers (working on off shore oil rigs in the Gulf). The divers love the Salt Series knives so much, they won't dive with anything else anymore. I receive pictures from them about once a month and it's been very interesting to hear their experiences. These divers are in some of the toughest environments under water and they don't have much time for maintenance, so they really have come to depend on the performance of the Salt Series.
I hope this info helps. Please let me know if you have any other questions.
Kristi"
