Laughing Cow Cheese (probably others) uses carnuba wax for the wrapper. That's a cheap source if you like cheese.

PS This is my 'magic' final coating for knifes. (I shouldn't post this - I should sell it. But, we're all pals.) It's all non-toxic stuff - so it's ok for kitchen knives too.
Equal parts of:
Purified Beeswax
Mineral Oil
Anhydrous Lanolin
All stuff available from drug stores. Melt however much in the microwave. All three dissolve in one another so they won't separate on you. Creates quite a nice cream-wax.
It adds luster, protects from rust and such, and resists finger prints.
Rub a small amount in with your finger over everything. Buff off with a clean towel - lots of buffing.
