Matt Smith put his degree in Computer Science to good use as a software developer, before quickly realising he didn't want to do that forever. After exploiting digital systems for fun and profit, the crossover into the family business of locksmithing came naturally and he became the 7th generation to assume this profession. Initially the skills were put to dubious use but then a legitimate career emerged after devoting many years picking what were previously considered unpickable locks, and making tools to do so.

Now, he does physical security consultancy, training and designs/sells high security lockpicks for professionals. He also designs high security locks, which he thinks are definitely unpickable!
