I have just been listening to an audio book version of a Dr Who novel: The ambassadors of death.
At the end of the story, a disgraced general picks up a his swagger stick and is arrested by the military police.
I thought I have no idea what a swagger stick is for. By the magic of the Internet I know now and my life can go on. I assume it is no longer used to beat squaddies. I would rather have a sword or machete.
