I have tried the multi-step burnishing processes with poor to horrible results. I had one attempt turn the edge to mush and caused the whole room to smell like a certain male bodily fluid. I am still searching for the proper technique. i still have to try a couple different things but i have a basic process that goes like this.
Skive/bevel the edge
Sand the edge
Apply water to edge
Rub vigorously with canvas
The result I have had was a very shiny slick edge. There has to be something else, some chemical that wont react to the oil in the leather. I am also deciding between buying or making a burnisher that will fit in a drill or drill-press.
If anyone has some tips or techniques that would help us out please post a reply.
