The heaviest object sword-swallowed is a Dewalt D25980 demolition hammer weighing 38kg (83lb 12 oz). Thomas Blackthorne (UK) swallowed the 24mm (.94 inch) thick drill bit, then held the full weight of the hammer and bit for over 3 seconds, on the set of "Guinness World Records - Die Größten Weltrekorde", in Cologne, Germany, on 23 November 2007. The hammer was switched on.
