John Harding has been in engineering one way or another since he left school in 1959. First as a Panel Beater, he then managed a hand tools store for around 10 years in the 70s/80s, selling hand tools, cutting keys and repairing locks and repairing, refurbishing and selling used hand tools. In 1990 he bought the Key master franchise for Bristol passing the BLI exam in 1994. He ran Key master (Bristol) until 2011 when he retired. Since then, he has retrained as a trainer for safe use of abrasive wheels and grinding equipment to PUWER 1998 and has also found his previous tool shop experience invaluable in the re-sharpening, hardening & re-tempering of chisels and other hand tools.
