It appears from Wikepedia that there was a John Wyatt in Birmingham at the zenith of sword making and involved in steam machinery and in particular cotton mill machinery but rubbing shoulders and involved on the periphery with the great sword makers of that time. viz;
Quote" 1738: Lewis Paul and John Wyatt, of Birmingham, patent the roller spinning machine and the flyer-and-bobbin system, for drawing cotton to a more even thickness, using two sets of rollers that travel at different speeds. This principle later becomes the basis of Richard Arkwright's water frame.
1741: John Wyatt, mechanic and inventor, designs and constructs a cart-weighing machine, later referred to as a compound lever weighing machine; the design works by way of levers that hold in place a platform, no matter where the weight is placed the load is transferred to a central lever. Weights attached to that lever then help in obtaining a reading of accurate weight. The simplicity, efficiency and accuracy of the weighing machine proves extremely popular across England, subsequently weighing errors are reduced to approximately one pound per ton, this remains a high standard of measurement into the mid-19th century." Unquote. So although I am unable to tie him down to sword blades it could be that he became involved ...or it is purely speculation...
