Seeing as you are using a cocobolo burnisher like I do I will share my 2 cents worth. After sanding edges smooth with 220 or higher I use saddle soap on the edges then burnish with the cocobolo thingy on a dremel I use it about 10,000 rpm. I then rub on a mix of 50/50 beeswax and parrafin that I melted together and formed in ice cube trays. Then go over it again with the burnisher. Heat is the key. You want to produce enough heat from the friction to melt in the waxes into the edges. Simple, and quick.
