An important study for sword swallowers worldwide:
In his report, published in the British Medical Journal, Mr Witcombe wrote that sword swallowers knew theirs was a dangerous occupation. Because he could find only two reports in the literature of injuries from the practice, he canvassed almost 50 sword swallowers to explore their technique and its side-effects. “Sore throats – ‘sword throats’ – occur when swallowers are learning, when performances are repeated frequently, or when odd-shaped or multiple swords are used,” he concluded.
