I have found several of these types of videos.  Apparently, there have been
efforts in several European countries to documents the old ways of production
before the practitioners have all died.  I have found French, Spanish, and
German videos so far.  One video, related to this whetstone video, is a German
one showing a bunch of old duffers cutting and shaping huge grinding wheels from
native rock.  It's amazing how just a few men could cut and maneuver a huge
stone using just picks and pry bars.
