I've always had a hard time finding a torque wrench. While I'm waiting for my picks to arrive, I found out a perfect homemade torque wrench: the bendable metal clip for a lanyard. If you bend it out straight, the end is just perfect for normal locks.
Anyway, to get to the point, I found a generic "Masterlock"-esque lock, and went to work with my lanyard clip and paperclip. WIthin 30 seconds, it popped open!
I'm addicted already.
