Put the fat bevel flat on a stone or diamond plate. Keep that angle and get the whole edge until there's a burr on the left hand side.
Then do the same thing to that side. Line the bevel up so the ANGLE is the same, then when you've got a burr along the entire right hand side (big bevel) THEN strop. I use leather with some sort of compound. There's a green brick somewhere that people get pretty good results with.
