  Mood:Ninja, plz...
Perfect single-crystal diamonds of more than two carats (the average engagement ring is less than a carat) churned out in a day. Scientists create the gemstones using a process called chemical vapor deposition (CVD), which grows diamond crystals one carbon atom at a time.

The jewelry industry has shown great interest in ersatz versions of the 45-carat Hope diamond, but other uses could prove more lucrative. Using CVD, scientists will be able to cheaply mass-produce diamond semiconductors that are hundreds of times as powerful as their silicon counterparts.

So, when can I send off one of my sword blades and have the edge diamond-reinforced?

Edit: And can they build a super-intelligent computer AI into it at the same time? ;]

I read a sci-fi/fantasy book where the main character had a blade made where the actual blade was diamond wrapped/reinforced with metal. He wrapped it so it would not be quite so obvious.

There's a blade I'd like to work with.

Diamond is tough to grow on steels - no one has really done a good job of it. Typically diamond coated cutting tools are made out of tungsten carbide.

Keep in mind that diamond is very brittle (compared to metals). Coating an instrument like a sword would not much use, since it will probably chip off when you strike. Obviously a blade made out of diamond would not last a single swing.

There are some other excellent options though. Titanium nitride and DLC coatings will significantly reduce wear. Of course, then it is harder to sharpen your blade. I doubt they coat swords with that though. I dunno how many people you've whacked with yours, but I doubt most people's swords get much use these days.

I was thinking a bunch of microdiamonds embedded in the blade edge would lead to a tougher, extra sharp edge. Certainly an all-diamond sword is a terrible idea.

I doubt I'll ever be so unlucky as to have to pick up sword in self-defense. And since that's the only way I can see myself killing anyone, I think my swords will thankfully never taste blood.

Hey, just as long as it's not named Armstrong... ;)

It's news like that that makes my day. DeBeers-- you're on notice, you greedy, price-inflating bastards.
