I used to work with a group of historical re-enactors, we used to do jousting tournaments and demo's of other medieval weapons. I was just the schmuck who carried shit around. But I got bored whilst waiting for things, and started playing with swords. They were too heavy, too wieldy for my weedy muscles, so I downsized and downsized and eventually found my niche with bayonets.
I idled away many a freezing cold afternoon whilst waiting for the big guys on the horses to need me, twirling and throwing and just generally getting jiggy with those bayonets.
Sadly, like skateboarding, it's a skill I once did well at, but have not practiced for so long that I suspect if I picked one up now, I'd be a blithering spazz. Shame, that. I'd like to take it up again and work at higher levels, one day.
