New 1660CB Composite Blade Leek pictures (with 3D bonus!))

Took me some time to view the 3D, but now I am able to see it, it's really cool.
Thanks for making and posting those pics.:thumbup: You're a real good photographer.

The normal pictures are nice too. I really like the look of the composite blades. That leek is one of the nicest I've seen so far.
Especially this one looks interesting:

Before, I thought the three metal layers were parallel(like in laminated), but on that picture it appears that the copper "crosses" the entire edge on that point.(Copper line continues on the edge)
That would mean there isn't any D2 behind that point(not that it would be necessary)

I've highlighted the part I'm talking about in the next pic:

So if I'm correct, in a composite blade the steel is layered horizontal(when looking at it edge down), with a "curved" form,
while in a laminated blade, the steel is layered vertically in straight sheets.

Looks like an even more innovative technology than I thought before.

It's pretty cool technology that they've given alot of thought to...the irregular weld line adds weld strength by creating a longer weld surface for a given blade lenghth. The concept used with the JYD2.2 composite blade adds even more strength because of the interlocking pattern at the weld join...good stuff! :thumbup:

Glad you could see the 3D.
Thanks for the complements.

Kershaw's composite blade technology looks like it has quite a bit of potential. Here are a couple of older threads with more info about the underlying technology.

Thanks for that last link. There are nice pictures and very clarifying information in it.
For the other people that missed that thread, here is a picture from it:

Pics aren't as good as the rest of you, but I wanted
to point out how so very perfect one of mine is in uniformity.
The 2 steels join up at exactly the right spot.
I have 2 more, 1 almost identical to this one, and one
only slightly off. Just a hair.

I hope I don't get too attached, as my Dam Leek might
get jealous if I start carrying the CB. :eek:

Here is a photo that shows blades being assembled:

The copper layer goes between the two segments.

Actually I think all of them should join at exactly the same spot since the pieces are all cut identically. What it looks like is that the grind has been evolving since the first run. Look closely at the BOD on mine versus yours.
 
I posted this in the sticky pictures (sounds "dirty" :p ) thread but worth repeating here -

Good observation -
my BoD is also Mar 08 and its grind is different for the earlier BoD of Feb 08 -
and those are different from the earlier photos used for Kershaw's brochure and released photo -

The bottom two crops appear to show a hollow-ground blade...must have been a prototype.
 
The Composite Blade pieces are laser cut, so there will be slight variations from piece to piece, thus blades will not be exact.
