Adam welcomes back to the cave Riley Kolbow (aka @worksbydesign ) to check out his latest project: a nearly unpickable mechanical lock! We learn about Riley's iterative process designing this lock, the ways in which locks are most commonly picked, and the key that makes Riley's lock a challenge for lockpickers.
