can a blade be ao sharp that, when a silk scarf floats dawn across it, it will cut it in half?

Question

the movie the bodyguard, had a sword that kevin cosner had. it showed that very thing.

Answer 1

Complete fiction. I have a knife that's as sharp as a scalpel and it requires at least some force to cut something. A floating scarf is not heavy enough. A scarf held tautly would be cut by the weight of the knife, however.

Answer 2

I observed this ultradramatic trick in a action picture, some years in the past. Theoretically probable yet quite no longer likely. The handkerchief would probable could fall with precisely 0.5 of its weight on the two aspects of the blade. The blade would probable could be completely aligned alongside the path of the falling handkerchief , and not purely sharper, yet additionally thinner than that's now achieveable to grind a blade. considered one of those knife would probable be completely ineffective for the rest besides the reducing of falling silk handkerchiefs.

Answer 3

Such a sharpness is possible but it would have to be the tip of the blade is 1 atom thick then a namometer up 2 atoms thick etc etc.

Answer 4

if the required force is met to drive the scarf down at the blade precisely... plus air resistance shouldnt be so high so that gravitational acceleration would not hinder the force...

Answer 5

thats not a sharp blade thats called trick photography
