For sale is a 2" Lie-Nielsen plane iron for Lie-Nielsen #4 or #5 bench planes.  The blade is made of A2 tool steel hardened to Rockwell 60-62.  It is then double tempered.  The blade is close to a 1/8" wide which helps to prevent chatter when cutting.  The web site says these fit only Lie-Nielsen planes, not others like Stanley.  The surface of the blade is ground front, back and the cutting surface.  The blade is 7" long.  The blade does not have a micro bevel but one can be added after sharpening.  The angle of the blade is 25 degrees as shown in my pictures. ( bevel guide not part of sale).  The blade will be ready to use with just a little honing and then you can decide if you want to put on a micro bevel.  See pictures for these are part of the description.
