In 20 years service I flourished a sword only 3 times after training, all on parades, so I'd wholly endorse the cufflinks suggestion. The pair my parents gave me and which I wore on passing out parade at Cranwell are some of my most prized possessions and were/are worn very regularly in both RAF and civilian life. That said, when I retired from the Service my wife gave me a fabulous momento - a George V pattern RAF sword which hangs on my study wall and is a constant and very welcome reminder.
