Diamond Knife Blade

If your reading this you must be a bit of a drongo like me. I was the first drop kick to get caught.:rolleyes:
 
Epsilon; I know you are having a heatwave in AZ. I can tell by this post'g, you have been out in it to long without a hat.:D :D :D
 
ROTHLMAO!...

What I want to know is how come there's 15 views but only 3 of us admitting it?

I'm trying to decide if you can profile it with lightning bolts Dave! HMMMMMMM:eek: Anyone have the phone number for Debeers!:D
 
YES,
You got me, but guess what! The Crucible process or powder process might allow for the mixing of diamond particals in such a way that it
could be a partial diamond knife. Instead of carbides, you would
have diamonds. Sharpening might be a small problem, however.
 
Don how long do you figure before someone tries this? You could even do a thin core with diamond in it so you could shape the rest of the blade normally...maybe sandwich Timascus over the diamond core... Okay now I'm betting it's only a matter of time. :D

Mmwa ha ha ha. Ah, yes. The heat. That and boredom. It rained yesterday though, which was nice. Rain... aaah.

You still have to ask yourself "what if". A diamond blade. If you actually lucked out and found a flat long and thin piece then curfed (sp?) one into a blade. How would it perform? Can a diamond occur like that in nature.

I have asked myself this for sometime. Why not? It is not unfeasible, just highly unlikely to make one from a natural diamond. Should somebody actually find one, would you sell it? Or make a knife from it? Get the money for having a cutter/jeweler snatch it up or perhaps the challenge/performance interests you most? Questions, questions. I'd make the knife.

The real question in mind is durability. I'm not a rock hound or expert on the subject, but in metallurgical terms hardness often mirrors brittleness. See what I'm getting at? However, the tensile strength seems as though it would be so insanely high, could you even break it with bare hands? Would there even exist a yield strength? If so I would assume it almost matches tensile. Thing is, metals are polycrystalline. Diamond would be mono. So the mechanics may work differently. I am unsure and that may make all the difference, especially in the case of slip planes and polycrystalline lattices versus a singe crystal. Hmmmm. And Don I have thought about the Crucible idea also. I would be very curious to see if it could be done or something similar. I think there are serious but expensive possibilities there. Money may be the only real issue. Same reason I believe we haven't colonized Mars yet. :cool: Aaaaaaanyways, gimme your input guys. Lets test these theories!

shhhhh I wasn't here:cool:
if you cast diamond dust into the edge_ this would be cool
but sharpening it would be a bear for users.:confused:
 
diamond fractures tot easy for a solid diamond blade, i sold them for a couple of years part time. the henkel co, came out with a culinary knife a few years ago that was a chisel edge with diamond dust imbedded in some way on the edge. they sold it as a FOREVER SHARP KNIFE. it wasn't and they fizzled away
 
I've got a DMT Diamond Steel Diamond Sharpener..........I just thought this was the next new product evolving from that idea.
