This wax is based on a number of old recipes for water-resistant protective coatings. I stumbled across the recipe while trying to make my own waxed cotton. I've used it in my amateur capacity as a blacksmith, melting it over the barely-glowing steel shortly after taking my workpiece out of the forge. I've used it on the wooden handles for my forgework, but where it really shines (almost literally) is on the leather sheaths they end up in. I even use it on my stitching to keep the final knot in place.
The neatsfoot and linseed oil nourish the surface of the leather, beeswax improves the water-resistance, and a citrus-based drying agent means you don't have to wait for days to use your newly-cared-for item! The balm leaves leather almost imperceptibly darker and with a satin finish.
The wax comes in a screw-top aluminium tin, so you can chuck it in your rucksack if you're going out and think you might need some protection - remember kids, always use protection!
If you leave the wax in the pot for a while, the surface will dry up, leaving a tougher protective layer. This can easily be scraped off, and the wax below will be like new.
Warining: it's not suitable for items that will be in contact with food.
