Re: Shinken Rust Problem
I use a product called "Frog Lube". It is modern and old thinking product. Made from plants and safe on the skin. It makes carbon steel semi-stainless in my experience, kinda like seasoning a frying pan.
I used it on wood items also. I have sensitive skin and it does not mess me up. I don't know if it would
sit with traditional martial artist. Bottom line is I have no rust where I use it.
