The Speed of Light is the same for all observers.

On this note,

When you snap scissors hard enough, the very tip of the blades can pass each other faster than c. (no proof provided, something I heard in a pub)

What you heard in the pub is bull.

Not even REMOTELY close ... infact, not close at all. I believe the person probably thought "Speed of Sound".

But even then, I doubt the tip could exceed the speed of sound. The tip of a whip does exceed the speed of sound and that travels MUCH faster than scissors?

Not entirely, although worded ambiguously. I interpreted what he said as the caveat below, which like above is theoretically possible.

Tbf my post still stand as true, I just bust out the ninja edit as I was on my phone and typing copious amounts is a pain.

The speed of light is constant unless it is passed through a media and then it's effected by refractive index blah blah.
