Friction polish is a finish that cures from the heat generated when the wood is rubbed with a cloth or paper towel while spinning on the lathe.
The most common version (and most commercial friction polishes) are shellac based. They produce a very high gloss, but aren't known for resistance to wear.
There are also oil/wax friction polishes that are great for utilitarian items. The fairly common mineral oil/wax finish used on treenware is an example that is known for being 'food safe'. I make a version that I use on tool handles from boiled linseed oil, and paste wax that I liquify by dissolving in turpentine. Finishes the wood, but also feels good in the hands.
I make a friction polish using lacquer that is much more abrasion resistant than the commercial shellac-based polishes. Equal quantities of a good quality lacquer, lacquer thinner, and an oil - I use pure tung oil, but boiled linseed also works if you are satisfied with the slightly stronger amber color.
