Patent concerning tools

[Fredmad]

I search some informations concerning tools using racking or overlifting (reverse picking) methods.
If someboby knows any patent concerning tools using these methods it would be great for me if possible to have some link.
I need that to explain the history of opening method during my courses.
Thank you.

I have been trying to conceptualize a tool like this for a year or so, but instead of sidebar locks, for picking a pin tumbler. I just wasn't sure if there was any kind of metal that you could cut into strips that thin and still get them to do what you want without binding or breaking. You would basically have the same pin by pin control of the lock like you were picking a tubular lock.

Phew - I was beginning to think this was a Frenchie-only thread!
If you mean "overlifting" tools, there are some discussions on the advanced thread relating to this. I don't know if there are patent refs though.
