Cutting efficient ?
« on: 18/09/2006 20:52:58 »
What is the most cutting efficient thing we ever created?

What you do speaks so loudly that I cannot hear what you say.

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

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  :-)

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).
