"Prior to the eighteenth century,
almost all planes were made by their users. This was
part of the 'ate and mysterie' that was imparted to
the apprentice by the master, and his early training
included the making of plane stock for the blades
the master provided.
There was little standardization of
form, and the maker was free to indulge his fancy in
style and decoration."
