Was just wondering if anyone has any suggestions as to use for maintaining stainless steel dive knives? Someone mentioned to me that after cleaning the steel it should be coated with some silicone oil. Or perhaps something else?
If you can take your knife apart completely, and coat it in some kind of grease it will keep the salt off of it. I use some old O-ring grease, but anything that has the consistency of vaseline will work. Make sure you don't get any on the handle, you don't want this to be slippery when you use it.
Of course you should always rinse the knife off and occasionally remove any rust that has formed.
I usually clean any rust that has started on my knife, and then I sharpen it to a razor edge. This is necessary for cutting fishing line or kelp. Then I coat the blade with silicone to prevent rusting. This works pretty could; I have been using the same knife since 1961.
I buy them at the Dollar Store. A nice set of four is $1.08 after tax. I make gifts of them- my buddies think I'm a great guy.
I don't even worry if LP is cheaper or how much the LDS is marking up. Life is good.
