In 1965 I participated in a cane rod making class at Esslemont School, Ellon. It was sponsored by Sharpes of Aberdeen, and the tutor was one of their rod makers. You started with the rough cane blanks and finished up with the rod of your choice, built to Sharpes specifications, As a matter of interest, which may be relevant to the current debate, the rods were finished with a few coats of good quality yacht varnish, applied very lightly with a fingertip. How things have changed !
