In 2016 there was a ruler trick thread going. I happened to have been given the two planes pictured. Because of that thread I decided to work up the newer of the 2 to show how I was taught to sharpen. I don't use the same ways now but it does work just fine. The plane is a newer Stanley, one that's not supposed to be quality. I did nothing to the plane. I took the iron out gave the bevel a rub on a medium/fine carborundum stone, laid the flat back across the end of the stone pulled back and out over the edge to remove the wire edge. Stropped it on leather with green. Tried it on rift sawn oak, hickory and the shavings are shown. Tried it on QS oak edge for thin shaving, it's shown. Did a little end grain on construction lumber. No back flattening, no ruler trick. You be the judge.
