One of the little known (well, to non-archers) but common problems with archery is that of the breaking bow.
No particularly common with the fibreglass, take-down composites or compound bows, it is - unfortunately - an all too common occurrence with wooden bows, and especially longbows.
Witness below - what happens when a wooden bow breaks at full draw (that is, the string pulled all the way back).
In nearly 20 years of shooting, I've only ever witnessed this event four times. And each of those four times the archer has stepped away from the broken bow with no injuries at all.
We thank all the Gods (and Goddesses) that she still has two eyes.
