I thought the same thing too about the sawing motion of the file. Not sure how I knew, but I knew that was a bad idea. Something about going with the grain, not against it?That video was pretty good. Notice he held the handle of the file in his left hand. Normally, you would move both hands together when draw filling. But when draw filling the file handle is held by the left hand. Why? Because the file teeth won't cut on the draw when the file handle is in the right hand. Single cut files have teeth that are cut into them in one direction only, so they can only remove metal in one direction. The push cut he demonstrates is the usual way to file but draw filing gives a finer edge, imo. If you try to file, with a single cut file, in a back and forth, sawing motion it will ruin the file in short order.
I found some things in the barn along with the ax, that need sharpening.
I've filed the pruning saw and the small clippers, working on the large clippers now. I discovered a makers mark, "Keen Kutters" on them, I'm going to go over them with a soapy brillo pad now to clean them up.
I'm saving the ax for last.
These are the "before" photos.
