I was looking at a Lie-Nielson plane today and noticed how different the chip breaker is. It is a flat piece of metal that looks like it has been ground on the blade side so that a little lip stick up at the end. The grinding marks really puzzled me. Like, how can they make it that way? The grinding for the majority is along the length of the breaker all the way down to the little lip. It's the all the way part that made me wonder what was going on. How can they do that?
What is the advantage of their chip breaker style over the bent Stanley type? What are the Hock breakers like?
