First off, no new inventions here. I wont make any claims to that as this is pretty old technology. Below is a picture of a CP Titanium/Stellite 6K diffusion bonded "san mai" sandwich in which I made a knife from. With major help from Darrell Lewis of Bodycote,(Thanks Darrell) we had a small piece of this material made up to try in knives. I gave the Titanium outer layers a quick anodize to show the Stellite edge better. It is obvious in the all natural form, but I am such a poor photographer with a poor camera it shows up better anodized like this. The material is about .160 thou thick.

There are some obvious advantages and disadvantages with the material. One disadvantage is the CP Titanium scratches rather easily. Next batch we will try 6AL4V for better scratch resistance and strength. Another disadvantage is it is going to be fairly expensive, but we have no idea how much it cost yet.

Advantages are exceptional corrosion resistance, and the cutting power of Stellite 6k. We may try a Talonite version and or different center alloys in the future. It is also much lighter that solid steel or other alloy blades. I plan on weighing it and comparing the weight to a steel bar the same size, but a guess is 20% lighter than steel. Not sure about toughness yet, but the laminate should be considerably tougher than solid Stellite, just dont know for sure yet.

We have done no destructive testing or cutting testing yet, but it should cut like Stellite 6K.

It was fairly easy to work, easier than a solid bar of Talonite or Stellite.

I have been kicking this idea around for years and have to thank the vision of Mike Snoody for his Sharp Fusion stuff kicking me in the butt to try this! Thanks Mike! :)

And here is the disclaimer, this diffusion bonded stuff is not to be confused with Sharp Fusion from Mike Snoody, Corn Fusion from Larry Harley, or any other fusion stuff! :D We just got to think up a catchy name now.......

Ill post another picture of the finished knife in the next day or two, thanks for reading! :)

Good one Bob! Right now that is a descriptive name. I should have sent you the picture to sharpen up, it always comes out darker in the forum than on my screen for some reason.....
 
Rob-

What a great effort. No matter what the results, you're sure to learn from it and push the envelope thereby. Thank you for sharing your development, and I'd love to see test results as soon as you have a chance to try it out.

Great work!

Thanks Will, you brought something up that so few people recognize, learning and pushing the envelope. I will certainly post test results, good or bad.
 
that looks like a Pikuni II in the image above.........nice!!

..stellar fusion.......


and "where are my neck knives" MAYO!!!! ..you pencil necked geek!!!!!!!:p :p :p:cool:
 
Rob, that's great looking stuff.

I bet you could get pretty crazy with annodizing the titanium in different colors and corresponding the G-10. [insert Homer Simpson-esque drool here}

As a someone relatively new to customs, aside from the weight and anti-magnetic properties the titanium adds, what are the primary reasons this would be advantageous?

Would this be more advantageous to someone looking at Stellite for their next blade or someone looking at Titanium?

Hope my question makes sense...
 
San Mayo?

Neat Rob, ir certainly is a good test for getting your grinds even. Now hurry up an anodize that whole knife so we can see the colors flash!
 
Nice work, Hunka.

Keep us posted on your progress.

Bet you'll have something really cool ready just in time for our next bout at Ruby's!!! ;)
 
Rob,

I lightened up the image a bit for ya. Not sure if it helped much, though.

TMW, that looks much better, thanks!

Blues, cant wait man! I dont think we talked about knives at all last time.

Yeah Jerry, you got to make sure to take even amounts off when you clean up the Ti outer layers. And it is anodizes as far as I can take it with my marking methods machine.

kawanin, it is! :)

Tom Mayo, Larry Harley already has the Corn Fusion name cornered. And let kawanin know that I sent the neck knife to you yesterday, and by the way, I need more stencils to mark your name! :D

cpirtle, the material is non magnetic, but it will not go through an airport metal detector, I took a piece of this and some 6AL4V to the airport and neither material made it through. The wands they are using also picked both materials up. You are right about anodizing, I dont have the proper equiptment to anodize it in rainbow colors. As far as other advantages over stellite or Titanium, it is too early to tell.
 
Rob, is Stellite conductive? I can see the anodize now. Heat should give it some color I would think. Can't wait to try some!

Yeah Mayo, and if you want me to drill the rest of those holes for you, you'd better send me a couple more drill bits! :D
 
HMMMMMM????

Rob,..Jerry,.... Sans Mayo.....



I wonder:confused: ...who else has a hand in making all those Mayo knives,.......




(besides those kids down the street):p :p
 
It would be like a Mayo & Onion Simonich.... get it... Simonich--Sandwich.... awe forget it... :)
 
OMFG that was the worst pun ever. And a mayo and onion sandwich would be too disgusting to eat anyway. Course, if all three of 'em teamed up on a "Talonite in Titanium" knife, it would be the...well, you know. Rob could grind the blade, Ken could do the handles, and Tom could do what he usually does...drill a bunch of holes and sell it as his own. :D
 
Jerry, I am not sure what you mean by conductive, but the anodizing was done cold, no heat involved. I used my electro chem etching machine and the Ti anodizes and the Stellite dosent.

Also Jerry, I went to the PO and got the package, I forgot you were supposed to drill the holes for Tom, so kawanin your knife from Tom will be delayed a few days while Jerry does the drilling! :D

Chad, I have never been drunk enough for that kind of sandwich! :D Please hold the Onion and Mayo!
 
Rob, my reason for asking if the Stellite was conductive had to do with putting one of the electrodes on the stellite, so I could anodize the titanium all over evenly without one of the electrodes getting in the way.

How about a Possum Sandwich with Mayo and Onion? :barf: :p :D

So now we're talking Hossom Possum? Definitely sounds like a sandwich that could bite back. I'm not far from Ralphing here, boys.
