This is one of my many planes. It is a wooden one, but the wear on it is from sweat, and use. It never had wax on the sole. You might notice that most of the wear is from shavings going up in front of the iron.
I had a friend watching me plane some boards once, using no. 6's if I'm remembering correctly. He asked why I didn't pick it up when I pulled it back. I told him I did. He said it didn't look like it. I asked him to listen for any dragging sound when I pulled it back. He said there was none. Efficiency is not doing any more than you need to.
The force using a plane only needs to be almost all forward. That "almost all" is hard to describe with words. None is needed down. If you notice a difference, you are pushing down too hard.
