|The back of the plane iron must be flat.|

Yesterday, I got it out to show my apprentice, and I became more curious about it. I used my set of Japanese water stones to get it ready for use. So this afternoon, I had a cross-cultural recreational experience, using objects from three continents.
First I polished the back side. Despite what you may see on the Fine Woodworking website, the object isn't to turn the backside into a mirror in which you can see your face. But in order to get a good edge, both the front and back must be polished, at the very least at the cutting edge. In the series of steps shown in the photos the object is that both the back and secondary bevels shine.
The drawing of a similar plane below is from The Teacher's Hand-Book of Educational Slöjd by Otto Salomon. The brand on mine is IPBO, stamped on top, and the plane iron was made by E. A. Bergs Fabriks AB in Eskilstuna, Sweden.
Tomorrow, I'll put it to use.
Make, fix and create...
