The Sharpest Tip

Looks like researchers at the University of Alberta are one step closer to creating "The Subtle Knife".

Forget the phrase, "sharp as a tack." Now, thanks to new University of Alberta research the popular expression might become, "sharp as a single atom tip formed by chemically assisted spatially controlled field evaporation." Maybe it doesn't roll off the tongue as easily, but considering the researchers have created the sharpest object ever made, it would be accurate.

Hmmm, beware the Spectres.
