Title: Laminated Coco Bolo Hunter
Post by: kbaknife on January 24, 2011, 12:33:00 PM
This one is a result of a lot of challenges for me.
I got the original inspiration for this from fellow knife maker Matt Bailey.
When I saw his knives this past year at his table right next to mine, I was sure he had been laminating Damascus on top of a high carbon core. After some cajoling on my part, he explained his process of laminating 203E to his 1095 and W2 core steels.
For those who don't know, 203E is a 'pressure vessel' steel - think propane tanks. When was the last time you ever saw a propane tank rusted through? There is enough nickel in 203E to make it HIGHLY! corrosion resistant, yet not so much to inhibit carbon migration.
203E has been used for decades as a Damascus nickel layer due to its propensity for carbon migration, yet enough nickel to etch in the Damascus contrast we all enjoy.
Here we see 203E as the outer laminate on my hunter.
As we grind on up through from thin to thick, I exposed more - to - less of the carbon migration from the welding process, and this etches out in a graduation of hardness giving the appearance of a "Damascus-y" display.
It is really rather lively in person. Right along the bottom edge we get this shiny pure iron layer that makes a nice "frame" for the laminate.
Mated all this up with 416 stainless take-down fittings and a Cocobolo handle.
(Thanks, Matt)

Way to stick with it Karl. For those who know anything at all about this stuff, that is an accomplishment. Nice even forging to boot. Lin

Nice job, looks like a few old propane tanks are gonna be hitting the bandsaw(empty of course)  Will a propane tank be straight 203E?  Anything else added for that particular application?  Thanks in advance.

I truly can't answer that question - I don't know if anything else is included when they manufacture the exact tank, I just know that 203E is the main steel.
I was able to get some of the raw bar stock of 203E, then just welded it up and went through my series of failures to produce a usable knife.

That is simply incredible.  One of the neatest knives I've ever had the priviledge of laying eyes on!

Thank you so much for sharing.

Just awesome Karl.... I love it.  That looks so much like refined wrought iron it isn't even funny.

It would be real interesting to see if you can get a similar patterning with any mild steel... I still wonder how much of it is more due to thickness of the mild steel jacket.  But... even if you got the patterning it might not show as well without the nickel to aid in etching differences...

Anyway... congratulations and I can't wait to see what else you do with this process....

I think you are correct, Scott.
The layering effect might be similar simply through carbon migration, but it's the nickel that gives it the contrast.

Karl,

That is an amazing looking knife. So, does it perform well or is it just a pretty face?

With the 1095 core having quite a "supply" of carbon, with what little loss I experienced during the laminating process, it should be a great performer.
I've done some hacking and chopping on some dense bamboo I just got in from California, and it seems to do fine.
I'm about to take one to a Texas hog hunt with about a dozen other guys and put it through its paces.
Should be plenty of proving ground right there!

Congrats on getting it "figured" out Karl, like I said this afternoon. Great job on one awesome knife Buddy!

Karl, that is very nice.  I appreciate your explanation.  
That looks like it was quite a venture.
