... these little laser whip finger thingies that they activate by touching (or pulling) their fingertip and then producing a thin little whip that they use to slice through people?

I think they used it to strangle and decapitate a guy... and slice through another one.

Was it Highlander 2?

For the life of me I can't remember!!!!!

Johnny Mnemonic. Monomolecular filament. In the story it didn't glow, it was invisible.

That's right... JM: The Matrix Preloaded.

Thanks.

"I want room service!" was the worst line in any movie ever... I'm glad Val Kilmer dropped out.
