I know we have stainless this and stainless that and wonder bar steel etc.Titanium,so it won't rust,doesn't make an all round good blade material though.Sharpening is maintainence also,if titanium doesn't hold a good edge or is hard to sharpen then it really isn't maintainence free either.I don't think wiping down a knife with a tuff cloth or a drop of lube in a pivot area on a folder once in a while is much maintainence.I've had very few problems with rust in my lifetime,even with non-stainless steels.If you wish to have a knife that doesn't rust under any condition,then I agree with going with talonite,but talonite will eventually get dull and require sharpening maintainence.It's a nice concept "Maintainence Free" and the industry has made some exceptional innovations.
However;In reality,if you gain in one area,you usually lose something in another.Whether it be edge holding,cutting performance,ease of sharpening,corrosion resistance, etc.they are all tough attributes to have in one type of steel.Well there is my two cents,but I don't know anything anyway,I'm just rambling.Take Care,Ralph
