Day #2 almost blended into day #3, the last day of the event, filled with lectures and a competition, just like the previous days. Mr. Cherepov showed his safe lock that uses a matrix key. Decoder talked about how he created a tool to pick the DOM Diamant lock. Jaakko talked about his research on safe combination locks that could lead to such locks being opened in a few minutes.
After that, we had a lever lock competition. Last time, this was an impromptu thing, this year it was a real competition with a record number of participants. With only 2 minutes per lock in the first round, this was quickfire picking. Still, all the 10 groups had at least one person open a lock. The fastest 10 then tried to open six locks in the final. Only Lars succeeded in opening all six, winning him first prize.
