This is a video of the fun-loving Aussies of Youtube channel How Ridiculous attempting to crack progressively tougher safes by dropping a 2-ton axe blade on them. They also destroy a bunch of other things in between. The finale, an absolutely massive safe, takes a very respectable 20 hits before finally giving up the ghost. That means if that were your safe, it would probably be pretty well protected from robbers armed with axes. Paul Bunyan would still totally f*ck it up though.
