You might want to look into some stainless steels. A high carbon will rust before you can get it out of the tacklebox. I’m working on one in AEB-L but it’s a personal project and I have a few orders to get out before I can play with it.What kind of Hi Carbon should I use for Fillet knives?? I had a request for 3. Also he wants me to use Cypress Wood do I need to stabilize it??
