The Abus 65/50 padlock has already been sold millions of times worldwide, and recently proved its worth once more when it foiled a locksmith and his 24" bolt cutters.
The brass padlock is marketed as a 'piece of balanced engineering and security' with a paracentric 5 pin cylinder designed to make it a very difficult pick, even for a professional.

It's 8mm hardened steel shackle is designed to prove more than a match for any cutting attack, a fact concurred by the locksmith in question and his broken bolt cutters.
