It is either a auto-bend spoon (http://aleena.com/tilford/video/autobendSilverware.html) or there are 2 handles, one handle that is completely detached from the spoon, and the second handle that is hidden between his fingers at the start of the video.
Use your brain for internal thinking, not external stupidity.
Glitch: I think it is like your second idea. In the beginning, he holds the spoon quite strongly and always covers the space between his thumb and index finger. In the end before he snaps the spoon, he looks at it suspiciously and that is the moment when he lets the detached handle slip into his shirt pocket (covered by his arm).

Even if it was real, you'll have to spend even more money to buy new spoons. It's a pointless skill.
