I saw this finish and as a novice craftsman wandered how it would be done?

Just get a regular propane torch like the one used for soldering copper pipes. Light it up and sweep the flame back and forth till you get the level of doneness desired. You can use a wire brush or light sandpaper to smooth out the finish or get rid of some excess char. Finish off with a coat of clear polyurethane or varnish. Good luck.
With the flame of a gas burner.
