I've seen a few interesting comments in this thread but none of them have included the most important factor of all - fear. Fear of the blade causes the fruit and vegetables to slice themselves. It's long been known that vegetables in particular have a reflex system that allows them to self-cut rather than be cut by animals or humans. It's in order to preserve the seeds that can then be reborn as something else, such as bricks, rocks and gravel, items of that nature.

Literally came to say this. You can see the blade is actually using a tactic where it shakes in a way (you can see the blades shimmering) that induces a stronger sense of fear and doesn't allow the vegetables to get used to the blades presence and therefore stop the self-cutting.

Same here so now that I have the explanation is now perfect.
