Just picked this little gem up on Engadget 
WARNING!!! Not for the squeamish though. 
Apart from that, quite interesting!

Tom, what kind of use are you going to do with it

Well, I noticed a difference.. depends on your cutting habits I guess..

it's OK to be "cutting edge" but this one looks too close to a "serial killer tool". if you know what I mean

As in that it won't splatter the deep red blood all around your gleaming white room, after you've bumped off the girlfriend?

I hate that "quantum leap" bullshit. A quantum is actually rather small, like electron kinda small.
I was never meant to be a surgeon, either. Nor a coroner.

Would it cut paper as well and tape and such I wonder, those are the only things I ever used a surgeons knife for
Otoh ... why would I ever want to layout PCBs with tape again ...
Anyway, looks like a cute knife thingie, not really suitable for killing, better bring an ax for that.

Yes but the quantum "an sich" was quantum leap in thinking about nature.

I still don't understand the term. Sorry to be pedantic, I just don't get using a term that describes nanoscopic terms to be a big thing.

To me it refers to a sudden change rather than to a big one ... but also see http://en.wikipedia.org/wiki/Quantum_leap

quantum jump: a huge, often sudden, increase or change in something, an abrupt transition.

That thing looks great for my home surgery!
Like that wart I burnt off. I reckon that thing would do an even better job than my Goot!

WOW! I thought I was the only one in the world that felt that way.
Of course what the originator likely had in mind was quantum tunneling where an impossible potential barrier is breached by the statistical probability of the particle being on the other side, and the speaker just shorthanded it, eh?
Edit :
Ok its proportional (by eigen value) to planks constant. But just how big is a quantum anyway?

Well, perhaps Reichskommisar Bush will propose the term entagled leap in his next speech?

It was that ruddy film wasn't it? With knob who says "wow what a trip" when he comes out of it. Then you spend the next 2 years playing 'spot the naff sample' on every goa trance record, because rest assured it was the record producers fave movie

 No, no, no! T'is not like that my friend. Especially for the physics-preoccupied souls here :

| Quote: | It was really only a short step — a quantum jump, perhaps — between the idea of a sudden change and a sudden large change. That’s the meaning of quantum leap, which sounds like total nonsense to anybody who knows about quanta. But before you complain about non-specialists using it wrongly, consider the fact that its first recorded use in 1970 was in — the science journal New Scientist.

Seems to me the link justifies Rex's complaint. Is it not the distinction between the clasical concept of change being allowed in infintesimally small increments and there being a smallest unit of change (particularly in electron energy) -- the quanta which prevented the ultaviolet catastrophy. Which problem was the shard in the eye Newton.

Maybe as well, but the quantum leap is more about probabilities I think, the chances of a particle going through a barrier that could not be overcome by classical means.
And then there is the Pauli exclusion thingie which says that no two identical fermions can have the same quantum state, and I thought that one was overcoming Newtons problem. The energy difference between two quantum states can be very small, just a spin flip for instance, or larger like an electron moving into a "higher orbit" (or to infinity).

That is what I thought was refereing to when I mentioned quantum tunnelling

Well, you could just as well say a quantum leap is literally a "leap of a certain size". It just doesn't correspond to the physics-connotation of the word quantum. In Dutch you have 'kwantum-korting' ('quantum reduction on sales prices') that signifies the reduction in price you get when you buy in large amounts.
