The Lindsay-Lindsay #3 was made meticulously by Frank W. Lindsay, who is a recognized watchmaker, goldsmith and gemologist.  The numerous jigs and fixtures invented for a period of  five years for use in making this knife are masterpieces in themselves.  Every surface has been finished with unsurpassed patience.  For instance, the finishing of the male and female parts of the lock was stoned to a mirror to keep to almost optical flats for mating.  The stones and laps used to achieve this are less than 1/16 of an inch in size and required many days of hand work under a microscope.  The inside face surfaces of the handle have been finished to the same extent as the outside.  The corners and edges are kept much crisper and more square this way.  The folder is held together with screws and taper pins.   There are no glues or solders used.  All the parts are pressed fit.  This design made it possible for the inside faces of the handle to be engraved while it was apart.  A patent was applied for this design method.  The center 18K gold interframe was bright cut engraved.  The graver was kept polished to an extreme to accomplish this.  Humming birds were used for a theme for this piece.  They and parts of the flowing scroll are inlaid 24K gold.
