Let’s say I have two planes, one bevel-down and one bevel-up. I also have a plane iron with a bevel angle of 25 degrees. Let’s assume that this plane iron could fit into either the bevel-down plane (at 45 degrees) or the bevel-up plane (at 20 degrees). In both cases, then, the angles of the the two surfaces that define the irons’ cutting edge are at 45 and 20 degrees to the sole of the plane.
If all other things remain equal, will these two planes work equally well, or will the bevel-up or bevel-down position make a difference to the plane’s performance?
A secondary question: does the back-side angle of the plane iron affect how it cuts, or is it mainly the front-side angle that matters?
