You'd be forgiven for thinking this padlock was favored for good looks alone, but it combines style with true security. It was invented in Helsinki by an office machinery mechanic when he realized the rotating cylindrical discs of the cash register he was repairing were imminently suitable as a lock mechanism. Made of solid cast brass, the body has raised shoulders for extra strength and greater clearance and a stainless steel shackle. Each key is specific to each lock which itself is virtually pick-proof.
