When a locksmith was left with this huge safe on his desk, he realised it wasn’t going to be easy to crack into.

It was impregnable from the outside, with a seriously thick metal door. However, this safe-cracker, who goes by the name of unkapier was savvy enough to manage to gain access to the safe’s interior.

When he found out what the contents were, he was amazed.

Luckily for us, when this locksmith was given the task of trying to open this monster of a safe, he documented it step-by-step. He shared the images online, stating “I’m a locksmith, got to open this safe today.” And what a cool safe it was, the make of it is ‘Mosler’ who are now out of business but used to manufacture boxes and bank vaults from 1874 through to the 21st century.

It was a known fact that Mosler vaults were impenetrable, so he knew he was in for a tricky task. These vaults were even used throughout the Second World War, and were installed in the Mitsui Bank in Hiroshima, Japan, and even survived the bomb dropped on the city. We’re unsure as to whether anything these days would be able to withstand such force.
