What is the most cutting efficient thing we ever created?
What you do speaks so loudly that I cannot hear what you say. (https://www.thenakedscientists.com/forum/proxy.php?request=http%3A%2F%2Fwww.activity4life.com%2Fphoto%2Fsheepbouncing.gif+&hash=159acaa741febc5b65a3b1d93c7395d2)

I'm sorry I have to ask you what exactly you mean with "efficient".

Hey babe now what do you think it means [^]

I don't know. If you take a 100 tons knife and you make it fall from a 100 meters frame, it would cut a lot of things, but at the expense of a lot of energy. So, if it's energy wich you are talking about, a normal high quality knife could be more efficient than a laser cutting device for industry.

There is clearly no single answer to this question, because it depends what you want to cut. a diamond is not much good for cutting foam rubber and a hot wire isn't much good for cutting steel and a hacksaw isn't much good for cutting glass. Its like a game of paper scissors stone :-)

Exactly.

So if we had a top of the pops of sharp thing what would be number 1 ? I think i have the answer but i could be wrong (i often am) so come on get off the fence and give it your best shot. Or should I say stab! LOL [^]

Probably it would be a diamond blade, since it's the hardest material I know. If we can talk about a device, instead of a physical blade, then I would say an X-ray laser (little wavelenght) or a very thin, highly energetic, electron's beam (same reason as up).

Sharpest Manmade Thing
A field ion microscope (FIM) image of a very sharp tungsten needle. The small round features are individual atoms. The lighter colored elongated features are traces captured as atoms moved during the imaging process (approximately 1 second).

So, which is good at cutting which?
