Jack of All Trades, Wednesday, Per 1

"Sup, class," Hardison waved a soda can at the students as they entered the Danger Shop. "So, hopefully everybody had fun last week, but now we're back in the classroom, 'bout to learn somethin' useful." Again, he gestured with the soda can, over to several tables with enough space for everyone to sit. At each setting were several odd items: two bobby pins, an empty soda can, a pair of scissors, a doorknob, a padlock, and a combination padlock, the type that were often found in lockers. "Today, we're learnin' two quick an' easy way to pick three different kind of locks." Looking a little embarrassed, he added, "Uhh, standard teachin' disclaimer--I'm teachin' y'all this in case it comes in handy someday, don't use it on your fellow students on the island."

Off the island, well, he'd assume the students had a reason. And as for the adults on the island...well, likely they could take care of themselves.

"Now, most doorknobs have pin an' tumbler locks, which means there are tiny pins inside that, when you push 'em to the right position, will allow the lock to open." He pulled up a giant image of the inside of a lock. "The pins are in two halves, you see?" he continued, turning one section of the pin red, the other blue with the touch of a button. "The space in the middle is called the sheer line. The way a key works is that it slides into the lock, pushin' the pins to various heights so that their sheer lines all line up, an' then with a twist of the key, the mechanism turns over an' the lock unlocks. Now, keys are nice when you got 'em, but sometimes you're workin' with what you got on hand. I gave y'all bobby pins, but safety pins work two--any slim piece of metal that you can modify into shape. A thin enough knife blade'll work if that's what you got on hand." He was trying to cover as many times as he could, assuming that not everyone would have access to bobby pins throughout history. "You're gonna need two: one to be the pick, which is what you'll use to adjust the pins, and the other to be the tensioner. That just sits in the bottom of the lock, keepin' a steady pressure on the mechanism so that once all the sheer lines are lined up, the lock'll pop." He then went into detail on how to shape the bobby pins and then use them to pick the lock. Once his explanation was over, a transparent lock appeared at each student's place. "You can practice on that one until you get the hang of it," he said. "Then y'all can move onto the door knob, where you'll be relyin' on sound an' feel."

Before they could start on that lock, Hardison moved on, picking up his soda can and the pair of scissors. "Next, I'mma show you how to use a soda can to jimmy open a combination lock an' a padlock. Don't even worry about the combination or how the lock works--this is more a brute force technique that works because of how the locks are used. Padlocks an' combination locks work by holdin' two separate pieces together. Remove the metal bar an' suddenly the individual pieces are free to open up. So you don't gotta know how to pick these kinds of locks, cause all you wanna do is get that bar outta the way. An' the trick to that is exploitin' a vulnerability in how it connects." As he was saying this, he was busily cutting off the top of the soda can and cutting out several large squares of aluminum. Once the squares were free, he modified them a little further into M-shapes. "This is a shim," he explained, holding up one of the M's. "Or, it will be when I'm done foldin' it. An' once it's properly shaped, you can use it to pop a lock like this, easy."

Once he was done with his demonstration, he nodded at the assorted items in front of them. "A'ight, you saw what I did. Now you practice. Class is over an you can leave, well, as soon as you can leave."

Rey had never actually had to do this, but she was paying attention. Because you never knew, right?
