 Great Knife!
I had a few Archeology classes back in college (Idaho State). Professor Mark Plew was a world class flint knapper who made surgical scalpel blades out of flakes of obsidian back in the late 70's and was a contemporary of Don Crabtree.  He told us when a thin flake is knocked off correctly the edge is the sharpest any man made edge could ever make. The reason is that the molecular structure of the obsidian is such that it can cleavage all the way down to the last molecule. Thus giving the sharpest edge possible.

Adrian:) Steve just posted a link to Jay Fisher. He sure is a talented artist in his own right but you certainly did him proud on this knife. I look at a lot of other designer's work for inspiration. I have a big journal full of ideas and stick drawings. LOL I cant draw worth a toot.
Your knife is so breath taking Adrian,  first of all you made it entirely of stone and out of your own imagination and skill. Then again you have inherent talent of knowing what looks good together as true artist. I think rocks love you Adrian:)

Good information Philip.

Amazing work on the knife.  And the obsidian is just beautiful.

Silly question though.  How did you attach the pieces?  Just epoxy, or some sort of joining mechanism?

Jon, the pieces are glued with epoxy, indeed.

Thank you again,

Whether you think you can, or you think you can't, you're probably right.

Adrian that is just outstanding!   yes16

I could picture a beautiful dagger with a Morrisonite handle made the same way. 

I studied a lot of archaeology while going for my MA.  Flint knapping always intrigued me and I have always had great respect for people who could knapp stone and carve and polish it to such shine and beauty. 

You have a real talent Adrian.

Oh my this is simply lovely.  The handle is perfect for this and almost looks like it grew that way.  Outstanding workmanship and I look forward to seeing more of your hard work.

Adrian...........I don't know how this thread slipped by me.....this is the 1st time I've seen it...................... hide35

That is some fonominal workmanship.  The shine on the obsidian is out of this world and the picture jasper (always close to my heart) is a perfect match for the handles.  All I can say is Phewwwwwww................

That is one amazing knife. How long did it take you to make a the knife? It's a work of art. Nice positioning of the picture scene on the grip, sweet! Ajo.

Adrian, that is just abut the prettiest thing I have ever seen. WOW!

You guys and your knife handles and now this.
Will have to try my hand at the handles first. Maybe in the new year. Would sure like to learn.
They are all works of art.

We LOVE your knife, Adrian! Tutorial ... TUTORIAL!!!

BTW, Here's Wikipedia on Obsidian sharpness:

"Obsidian has been used experimentally for blades in surgery, as well-crafted obsidian blades have a cutting edge many times sharper than high-quality steel surgical scalpels, the cutting edge of the blade being only about 3 nanometers thick.[34] Even the sharpest metal knife has a jagged, irregular blade when viewed under a strong enough microscope; when examined even under an electron microscope an obsidian blade is still smooth and even. One study found that obsidian incisions produced narrower scars, fewer inflammatory cells, and less granulation tissue in a group of rats.[35] Don Crabtree produced obsidian blades for surgery and other purposes,[34] and has written articles on the subject."

We can easily vouch for that! We often find that our Davis Creek obsidian has bitten us only when the other partner points out the dripping blood ...  help26

Thankfully, the wounds are (generally) tiny, easy to clean, and heal very quickly. So, that provides an answer to the question "Do you miners ever get cut by your obsidian?"

"Uh ... Like, YEAH! DUH!!!"

Lovely blade, Adrian!
