I want to replace it with one that i can keep on the rib at all times for easy access and it won't rust. I understand that it needs to be of a surgical s/steel grade to ensure total rust proofing.
Is anyone aware of such a knife, how much and where i can get it from?
Surgical grade does not mean it won't rust.
I don't think that any grade of SS is completely rust-proof; some are more rust resistant than others, though.
The best procedure I've come up with is to keep a coating of silicone grease on all exposed metal surfaces on the knife. A handle that can be disassembled helps here, as you can coat the entire piece of metal. The grease lasts longer than oil does. Use a grease certified for incidental food contact, and you're safe consuming the evidence of being attacked by that rampaging salami.
I've got a Underwater Kinetics dive knife that has been on my gear for years with no discernible rust problems. I think it's made from 420 SS. Their new ones are some proprietary SS blend called Hydralloy.
I dislike the titanium knives because they're too light. I like the heft of steel, as it makes it feel like I've actually got something in my hand.
