Check out this item on Uri Geller, via James Randi.
[Geller] has selected one key out of a bundle of borrowed keys, and told a participant on the show to hold it between his hands, saying:
Here is a key. Try you're strong try to bend it with your hands. It's impossible is that right? It's impossible. No! Keys are impossible to bend!
As he delivers that second "impossible," Geller sees to his horror that the man has visibly bent it! You can plainly see that in the video in a brief extreme close-up. Look at the video frame shown here, in which you'll see inset at the lower left a magnified view in which I have accentuated the direction of the body of the key in red lines and the direction of the shank of the key in green lines. The fulcrum for the bend is of course immediately between the man's two supporting fingers, where the force is being applied. That's indicated by the yellow arrow.

, with a picture of Geller bending a key himself. Looks like hard work.
