Experience the legendary smoothness and edge retention of Aogami (blue paper steel) in a western metal bodied handplane.
This thin laminated replacement plane iron has been made and carefully heat treated for us by Tsunesaburo Hamono in Japan; they are a drop in fit and shouldn't require any modifications to the plane, no mouth filing, changing Y levers etc, just take the old one out and pop the new one in.
Honing angles are the same as for carbon steel irons (25 / 30) and being laminated they are a pleasure to hone freehand, keep them clear of diamond stones though as the soft iron supporting layer can damage the diamond surface.
