If you would like to brush up on your lock picking skills, you may be interested in a new product available through the online Adafruit store this week in the form of a large clear practice padlock. As the name suggests, the practice padlock allows you to see exactly what is going on within the lock, enabling you to hone your skills to perfection.

Thanks to its transparent design it’s easy to see the padlocks chamber, tumbler alignment, and seven pins and is a great gift for the men mechanically curious or budding locksmiths. “In a province somewhere in Tamriel, you’ve been stuck in a dank, dirty dungeon cell for who knows how long. You shake your chains at a rat scurrying across the stone floor into the pockets of a fellow cell-mate sleeping off a bottle of contraband ale. The rat scuttles back out with three lockpicks in its tiny rodent maw, and drops them next to you. Your first attempt breaks immediately in the padlock cylinder. Growling, you pick up the second lockpick and try again.”

The large clear practice padlock is now available to purchase, measures 50 x 44 x 22mm and weighs in at 116g.
