I encountered this problem and although I m sure you re all familiar with it,
it might be new for some new members.
So the thing is: the more you pick the lock, the more you damage it.
Yes, you probably all know that.
But what "damage" does it inflict?
The springs and the pins will wear and they will stuck in the bible or won t move at full lenght. They usually get stucked AT the shear line, which makes the lock can be opened WAY TOO EASILY!!!
I had this lock I couldn t open for a long time. I practised it for many days
till I could open.
And then....I could open it again and agian and again with less and less effort. I thought that it was me, who gained experience, but actually the damage I inflicted to the lock played an important role too. Sad story.
Now only 1 pin holds it, the other 4 are stucked.
If you have any ideas how these locks could be "resurrected", please share with me (us)!
Oh, I almost forgot: this is a video explaining overpicking:
