The smallest knife?

Found an article that I thought might interest some folks here. Not ready for EDC duty yet, but it makes you wonder (well, it makes ME wonder, anyway ) what is ahead for cutlery.

Enjoy all.

Now that's interesting.
And for once, I'm not looking at it from a knifeknut angle. I've cut tissue embedded in wax to make histological coupes, it's not easy at all. Make it too thin, and the knife will just rip up the slice. Make it too thick, and you'll see nothing under a microscope.

We used a replaceable razor blade for long razors btw. It used to be fixed blades on those machines (to be sharpened with a stone), but they're not used anymore. "Because noone knows how to sharpen them on a stone anymore, save for a few old laboratory people. It's too difficult." (quoting my teacher last year). I really had to restrain myself not to shout: "I know how to do it. And it's not difficult at all...bunch of sheeple!" I mean, how difficult is it to put a piece on metal flat on a stone and slide it across. It's not like your putting an edge at an angle of 30° or something. It's flat ground, and thin as heck.

Cool. Thanks for the link. I love reading about what is on the cutting edge of technology.
