Nanomachines, son

Never mind... I am stupid... she is holding it an putting pressure down... .-.

... I had to face palm and then unfacepalm in like 2 seconds

Then how did she take the picture if she is using the other hand to put pressure. Eiter someone took the picture or she took the pic with her mouth.

Or maybe.... she's holding it with her mouth O_O

it's a ceramic knife

"Let's take a picture"

We would see a lot a' blood.

unless it was a hot knife. So hot she cauterised herself

That doesn't look like ceramic though. You can break any knife if you are doing stupid things with it. Using it to pry things open, jamming it into things, etc. Also putting it in the dishwasher can cause this. The high heat messes up the steel, making it more brittle (and harder to keep sharp) which means more likely to break. That's why you should never put a good knife in the dishwasher.

steel rather bends than breaks, and if it breaks you can still see a little bit of the bending around the breaking edges.
