You've heard of a paper shredder, but this is a hand shredder. Often used by the mafia when they want to remove fingers.
Just kidding, it's a hand-operated paper shredder. And, it was seen on TV! Oops, no, it is just "Similar to items seen on TV."
OK, now that I have made fun of the paper shredder, I have to say that it is actually a good little shredder. I like that it is manually operated (instead of electric) because I think it is safer to have in a household that has kids. Also, the blades are hidden, making it difficult (but, I'm sure, not impossible) for a child to hurt himself. Yes, "himself"...girls wouldn't stick their fingers in a paper shredder. The death-and-destruction gene is on the Y chromosome.
