Captured in Slow Motion: Fencing Flick!

Canadian Fencers - Calgary EPIC Fencing Club
As per Wikipedia:
"The flick is a technique used in modern fencing. It is used in foil and to a lesser extent, épée.
The 1980s saw the widespread use of "flicks" - hits delivered with a whipping motion that bends the blade around the more traditional parries and makes it possible to touch otherwise inaccessible areas, such as the back of the opponent. This has been regarded by some fencers as an unacceptable departure from the tradition of realistic combat, where only rigid blades would be used, while others feel that the flick adds to the variety of possible attacks and targets, thereby expanding the game of foil.
