Kershaw Fans,

Please explain the composite blades on some of their knives?
The blade looks unusual so it must be like a carbide saw blade.
How is it bonded to the other steel? Welded?

Thanks,
ken
 
Yep, ken, they are what kershaw calls "pattern welded", with a thin layer of copper in between the two blade steels. The patterns not only give the blade an artistic look, but I believe they also help to strengthen the bond of the two metals by increasing the amount of connection between the steel, as compared to a straight line weld.

They're a really cool class of knives in the Kershaw lineup, and pretty soon, the Shallot will be out with ZDP-189 on the cutting edge and the brand new Sandvik 14C28N on the spine. keep yer eyes peeled!!:thumbup:

Yep, what JM44 said.

Current models are

1660 Leek w/CPM-D2 Edge and 13C26 Spine
1725 JYD II w/CPM-D2 Edge and 13C26 Spine
1850 Tyrade w/CPM-D2 Edge and 154CM Spine (limited 2000pcs)

New
1840 Shallot w/ZDP-189 Edge and 14C28N Spine

I'm sure there will be more offerings through the next year.
These types of blades offer the user a better cutting edge,
and the beauty of the blade at an affordable price compared
to the entire blade being made of the edge material.

I am pretty sure that "Pattern Welding" is the term used to describe the modern Damascus process and not what the composite blade construction method is called.
 
The two Laser Cut blade parts are Brazed in a Heat Treat Process using Copper material as the bonding or Brazing material. after Brazing the blades are annealed to allow for finish machine work,and then off to be hardened, after this stage of the process the blades are returned from Heat Treating and finish ground.

AHHH!!:eek:, you are absolutely right rb!! Thanks for pointing that out. I must have answered this one a little too quickly.:o

But......you did get the gist of what I was saying, right???:D
 
The blade on the Tyrade is just amazing. I think it has the qualities of a much more expensive knife at a much lower cost. and it just looks cool.
