“the scientists found a complex structure of layered calcite crystals held together by super-hard natural cement.”

Almost as if someone(thing) designed them.

But will the knives have the patented Accu-grip Control Ball?

[EternalVigilance]

But seriously, if this could be made to work it would have a tremendously positive impact on manufacturing.

Like a self-cleaning oven?

Their bite is worse than their bark!

Hmmm, self sharpening knives aren’t exactly a new idea, just expensive to make.

They are laminated with the hardest metal being a thin sheet for the edge. The metal then gets progressively softer as you move away from the edge. It then wears itself sharp.

Never sharpened, but the blade will wear down quickly. Sea urchins deal with this via replacement since they are alive. Blades? Not so much.

Now, make a living hardened steel blade that stays eternally sharp and grows to replace lost material, and we’re talking! Meanwhile, I’ll stick with hardened steel, high carbon steel, various alloys, and the like. And a good sharpener...

Forget the sea urchin.
What you need is a crysknife made from the tooth of
an Arrakis Sandworm.

"....and believe that technology based on the same principle could create everlasting bladed tools."

Sea urchins die - they are not "everlasting".

I'd like to thank the sea urchin along with the quail for pooping out the egg that makes the urchin so freaking delicious.

[RandallFlagg]

Reminds me of a custom lightsaber that someone had built.
By the hilt was the printed warning, "Do Not Sharpen."

Langoliers ping.

Frowning takes 68 muscles.
Smiling takes 6.
Pulling this trigger takes 2.
I'm lazy.
