Mine is not laying a plane on its side when not in use. In the old days when we had tool boxes with all our hand tools [power tools not invented yet] in was keeping the edge on the plane blade. I know back the blade off, but I forget easily. So in the box I made compartments for the planes with the front held off the bottom with a small piece of wood. A lot of pics on woodwork forums show the plane resting on the blade, my blood runs cold.
BTW most of our jambs were in need of a clean up, so I bought a Badger plane for the job., wish I still had it, I think it went the way of my german jack and the 4 jointer and the Stanley 45. But I have a mate who still has his 45 and is selling it to me.
