re: Best wood shaving from a handplane?

I’ll have to get a pic, but I was able to get a shaving or two off some knotty oak that I could read a book through. The plane is a fifties era Record no. 4 that I found in the rusty bucket at the tools refurb shop I volunteer at. It was headed for scrap because of chips in the top of the body. It’s brilliant and I love it.
