ELI5: Why are scissors "left-handed" or "right-handed," and why don't they work when you use them on the "wrong" hand?

This has baffled me, well, since I was literally 5.  Why is it that scissors only work in one hand?  Is it something with the blades?  I just remember picking up my left-handed friend's scissors and being so damn confused.

Because the way you grip scissors puts pressure on the blades forcing them against each other.  Using the wrong handed scissor causes you to force the blades apart, creating a gap in the blades that ruins the ability to cut.
