Why it works
Quoting from the article:
They found that hydrogen binding initiated a domino effect, with structural changes propagating from the sample’s surface through all the carbon layers underneath, turning the initial graphite-like structure of planar carbon sheets into an arrangement of carbon atoms that resembles diamond … [T]he scientists discovered that hydrogen binding resulted in the formation of chemical bonds between graphene and the platinum substrate.

Let me know what you think – a good sharp knife is so nice. The Kyocera ones are also very light weight – great for veggies.
I've heard of ceramic knives but do not own one. Thanks for the tip, +Bill Carter . My kitchen knives are really a disgrace, considering all the cooking that I do. I will be checking this out.
It might be because although diamond is very strong and stiff, relatively speaking out is not tough – many ceramics and metals have a higher resistance to fracture. Have you tried the Kyocera ceramic knives +Rajini Rao? I have one and it is awesome.
I should look around for them, +Bill Carter . My veggies would appreciate a closer shave, I'm sure 🙂
Cool result! I am actually not sure why you can't have that knife today +Rajini Rao. CVD diamond and diamond like carbon (DLC) processes have been around for decades now. You can buy diamond-coated cutting tools for machining and drilling. Even my razor blades are diamond coated.
It's all in the phase..phase transition, that is! A serendipitous discovery indeed. I'd like a diamond edged kitchen knife, please 🙂
