Hi Norman,
yes, i have some blades which were covered with shellac. Shellac becomes discolored and ugly after some decades.
I use Nitro thinner or Aceton to remove the shellac. After that treatment the blade must be oiled thoroughly.
If i have wood with shellac I use very fine sandpaper (from 1000 or 2000 to 7000 grain) and a metallpolish called "Gundelputz" for the finish (thank you very very much for that tip Alan Maisey!).
