As part of all the information on the benefits of a closely set chip breaker I noticed that honing it was part of the equation. I'm set to work on the one from my Lie-Nielsen #4 but want to make sure I have it right before taking it to stone. The side that rests against the blade should be flat correct? Don't think that should take long on an LN cap iron. The other side should be hone to 45* or greater with 50* or higher optimum?
