In 1919, locksmith and inventor Harry Soref had a thought: if bank vault doors and battle ships were built in laminated layers of steel for greater strength, why not make padlocks the same way? At this time most padlocks were hollow and could be easily broken by a hammer or similar physical abuse. Master Lock is now recognized around the world as the solid, enduring name in padlocks and security products. Generations of people have grown up with Master Lock products at home, school and work. Today, a whole new generation has discovered Master Lock's new and innovative security solutions. As the largest global manufacturer and marketer of padlocks, Master Lock continues to build quality and value into its expanding lines of security products. As safety and security gain importance with the world's consumers, Master Lock continues to develop products that offer smart security solutions. Founded in 1921, Master Lock continues to build upon its founder's spirit of innovation, quality, and good value for the consumer.
