The knife is a simple forged one. The para-cord is on cause it is easy and fast to change. This is just an experiment to see if washing, cleaning, and waxing each time on the water will keep it in decent shape.
I'm not concerned if it gets destroyed. Heck most of us destroy a blade just to see how well it was forged in the first place. I wouldn't expect anyone buying a nice hand forged high carbon steel blade to use it in these conditions. Yes I do have cheap SS knives that I use in salt....but they aren't mine.
Just trying to see what happens to one of my throw away blades on my boat
Even if it gets all rusty, it can be cleaned up & sent to St Judes next year with a warning "Don't use for Salt Water Fishing"
