Probably a stupid question...

I noticed this on a couple of knives, including my Kershaw Groove. Can someone please tell me what it does?

Without that deliberate weakening, the lockbar would be too stiff for convenient use.
 
Well...it is...a really...somewhat question. :P
But as you can see, not all of the knife guys can tell ya what it is.
Without the notch, I think the only creature that can really close the knife must be gorilla ;)
As you said, It appears in some knives, not all of them, cuz only thick liners or frames need it, the thinner liners dont
 
Obviously, that knife is coin-operated, like a pay toilet in Europe or a parking-meter... please insert exact change! ;)

Seriously though, as others have already said, that cut-out sets the 'spring' tension of the frame-lock.
 
Interestingly there are two grooves in that lockbar. In my framelocks, there are only one. I'd be interested though in seeing a design with many shallow cutouts extending up the lockbar towards the lock face.

You would then be making the entire lockbar weak and springy. I've seen up to three or four small cutouts lined up, but the majority have one large cutout while some have have a double cutout.
 
That's where you keep your pocket lint.
