I felt urged into this, it is a live experiment.  The handle does not want come off and I am not going to pull it off.  Now I have started I think I should go all the way, with guidance I hope 

 .  I hope my pictures will be good enough.
  I can already see that the blade is quite old and more pitted than I thought.  The juice does seem to be reacting and making darker looking areas.  If I wipe off the juice, it is at the moment a little more difficult to see the pamor/forging.  However when I inspect the blade with a glass I think more interesting patterns are being revealed.  I will carry on for a day or two, then come back with more pictures and attempt staining.
