Diamond knives in our future - could be

I guess the day is a-comin we'll have to put a laboratory on our list of tools to buy or make.

Roger is always thinking! I think the diamond/steel blades would kill the ceramic knife business once and for all. Speak about possibilities, But we know how cheap diamond ain't!
 
Diamond ain't cheap, but methane process they're using uses cheap materials. I just let some methane loose a few minutes ago. ;)
 
Anyone ever read The Diamond Age? At some point it'll become just as cheap to make stuff out of diamond (as in carbon) as anything else - one molecule at a time. Diamond is really pretty cheap. I'm holding out the for the solid diamond knife. :D

Wow, a diamond knife.

Now you can pry with a fillet knife, and it'll never need to be resharpened.
 
Diamond is extremely brittle though, so it would make a very poor knife in most cases.
 
The way I read the article, they actually GROW the diamonds on the surface - not imbed them. So, I THINK they mean you shape the steel, then the treatment grows diamonds on the surface :eek:

The carbon atoms present in the methane dropped onto the substrate and formed a thin layer of diamond there.
