The Kunz No.102 apron plane is a plane you will reach for again and again, due to its compact and handy size it can be carried in your apron pocket ready to use at a moments notice. The body is made from from fine grey-cast which is stress relieved and epoxy coated, the sole is then ground flat. The iron is produced from optimum quality tool steel and hardened to approximatly 62 Rockwell HRC. The plane iron is suplied sharpened but we would highly recommend you hone it prior to use, lapping the sole on 320g Wet and Dry abrasive paper on a flat surface i.e a piece of float glass will also take the plane to another level.
