Hi I am a person that can do edges like what peter was doing. I make and sell a burnisher that can be used on a dremel tool that can get edges lie this. I have had Bob Park use my tools and does like the effect it can get. Go to my website and look at the short video that I have there demostrating the use of my tool. www.leathertools4u.com. as for the wax, I use paraffin wax. I also use sand paper to get my edge smooth.
