This is gonna sound pretty simple Nick, but to me it isn’t that much different than sharpening a regular double bevel, except that I’m only gonna file the burr up on one side. I take the burr off by laying the flat side of the head lightly on the flat on the file and push into the edge. When I’ve worked it to a fine edge or burr, I strop it off like a regular head. I’ll likely have an ElGrande in my quiver this fall; maybe I’ll get a chance to use it.

I use a regular 0 cut bastard file and sharpen from the edge keeping the same degree of bevel. Roll it over and knock the burr off. I then clean it up on a diamond stone by pulling the edge to me, then pull it on a hard Arkansas, strop on leather one way.:)
