I made some 'fix n wax' using beeswax, Shea butter, some oil and some Pine essential oil. Can't remember exactly the details offhand, but it was from a YouTube vid. I melted it all down and poured it into some altoid tins. It's solid, but soft enough to rub into a bowstring, and I use it to coat my carbon steel knives and hawks between uses. It works great, I love the stuff. I lined the tins with wax paper,then after it hardened I popped it out, removed the wax paper and shaved enough off the sides to easily get it out to use. No rusty blades anymore and it wipes off easy when I want to use them. It's also safe to use on blades I use for food prep. I always have a tin with my gear. I've even used it on a few leather knife sheaths. How can you beat one substance that can wax a bowstring, protect your blades and treat leather?
