I just want to share my little experience.
You have seen the electric toothbrush called Oral-B? Well, I thought it could be a nice electric pick instead. So, I clipped the brush of one of the extra tips. Inserted a homemade small pick into the arm inside and glued the arm and pick together. So, now I got an electrick lockpick that works. And if I need more types of picks, I can buy extra brushes in the store cheap. And I can switch picks easily. Tried it on 1 lock, and got it open in seconds.
I will make a post later with photos so you all get the idea here.
