New Composite Leek and JunkYard Dog II!

I've stayed away from the JYDII because of the clip, just ole' anal me! But the JYD2.2 is looking like it will have to come to my house, clip or no clip! Maybe STR is doing some slimmer clips for this series? Those are both some sweet looking knives! Just Kershaw, being Kershaw.:thumbup::thumbup::D
 
Woah! I have only collected AO Kershaws in the past, but that JYD2.2 is definitely joining the collection.

But why CPM D2? Why not CPM 10V or CPM M4 Rex or CPM S90V or even CPM S125V - with composite blade grinding should not be an issue.

Thanks, Vassili.

I'm guessing (and Thomas correct me if I'm wrong) but maybe because
It's going to be a regular production knife. Not everyone wants super
steels like S90V, ZDP-189 are S125V. I don't think the average knife
owner wants to spend as much time putting an edge on a super high
end steel that some of us knife knuts do. I don't own a knife with CPM D2,
but from what I've read from owners here on BF's, it's a pretty good steel.

I already talk about this quite a bit - there is no difference in sharpening "regular" steel vs "super" steel. I never see difference and to me it is just silly excuse from lazy manufacturer who do not what changes. I actually never hear this from Kershaw. I hope I will never hear this from Kershaw.

Thanks, Vassili.

I don't think you will ever hear that from Kershaw. For God's sake man they took 2 steels and jammed them into one blade in a technological leap no one else was willing to take on at this price point. I believe that the "safe" alternative of trying to get "regular" steels to play nice is enough for the Second composite blade of this type to reach production.

As for "super" steels in the future....That's the whole idea. The best steel edges with standard steel spines. Just give it time.

I just spent 1 hour re-profiling 13C26 down to 12 degrees per side
and spent 3 nights doing the same with ZDP-189 a few months back and
using the same diamond stones.
No difference?? :confused:

Geez...who would have thought there was no difference going from something
that is 59-60 RC to 64-65 RC??
 
Well a couple of the reasons we turned to CPM-D2 out of the gate, one was that it showed off the contrast between the two steels. Not all steels available with this technology turn "dark" when drowned in ferric chloride. CM-D2 was perfect for this application. Since this is all new to everyone, we felt it important that the consumer could really see the that there are two separate steels being used within the composite blade. ZDP-189 looks great as well, but the steel is not readily available for prime time volume.

Eventually you will see other exotic steels being used, but were just getting going.

We did a CPM-154/13C26 combination, and it looked a bit boring to us. A copper colored line separating two steels with the same finish. I'll post a pic of it tomorrow so you all can see, and believe you will see what I'm saying.

Once we get some time into these composite blades, I don't feel the contrast will be as important, but with its initial debut, I think it is vital.

Also CPM-D2 is a new offering from Crucible, which I think is pretty neat to assist in bringing it to market. CPM-D2 is performance oriented, processes well, and IMO makes for a nice intro steel for composite technology.

Don't fret Vassli, we'll get that upper lip of yours sweating...just need a little more time.:D

Geez... What kind of crap do you use for re-profiling? Try DMT Extra Extra Coarse D8XX.

Thanks, Vassili.

CPM S125V or YXR7???

BTW, If steels in composite blade have different hardness then you may highlight difference by bead-blasting I thinks. At least it is very visible on Lauri PT after bead-blasting.

From other hand you may consider coper separation line as a main decoration element - do some primitive ornament. Like Greek, Slavic or Celtic.

http://bibliotekar.ru/ornamenty/1.htm (it is in Russian. link at the bottom leads to next page - there are many types of ornaments there - African, American, Celtic, Greek, Russian....)

Some repetitive pattern of like simplified three petal lily flower...

Also you may embed something other then steel inside blade this way - like gold for up scale models... or titanium...

Thanks, Vassili.

no offense but even if you have an xxc plate from dmt the two steels will take different amounts of time.....considering you are taking the same amount of material off of each blade.....harder steel=longer time on the stones.....it's as simple as that....ryan

i can't wait to try one of these composite blades out......it will be interest to see hoe the steel sharpens up....i don't have nay experience sharpening any versions od d2

It may be some difference, but it does not really too big to consider it as an issue and refuse to produce knives from good steel based on this.

To my experience time I spend on re-profiling mostly depends on edge thickness not hardness. Diamonds has superior hardness over any steel and so to me it is in general matter of how much steel need to be removed. Even coarse diamonds take away not too much and require quite some time for re-profiling (and this has nothing to do with steel hardness) until that D8XX.

But I constantely hear something like that CPM S30V hard to sharpen or anything else then 420HC is hard to sharpen - all depends on given manufacturer. Like they know better what I need then me (just because they have more profit or less troubles with existing steel).

Thanks, Vassili.
 
OK, here are the images of a CPM-154/13C26 combo. Thoughts compared to the CPM-D2 contrast variation?

Thomas, this is matter of how line itself looks. Try to draw simple ornaments. I think you need to talk to professional designer-artist. I think Ken Onion is the best person to talk.

Thanks, Vassili.
 
I like the very bottom pic. The others almost look, well, unfinished I guess is what I'd call it. I really like the contrast. I also noted with the Tyrade how stunning it is and the Wow factor it brings out in folks. Its all due to that contrast I think. Without the contrast I believe the reaction would likely be more like my wife's was looking at this Leek in the above pictures with no contrast, "what is that line there? Is the blade cracked?" I think a distinct pattern showing its meant to be there at the joining mark of the two steels would help distinquish it from looking 'cracked' Thomas.

I'll tell you something else I noted in using that CPM D2 in the first round of slicing and testing I did with it. The performance was not what I'd call all that outstanding. The edge dinged a little more than I expected and it made me struggle a bit to get through hemp and hard wood like I thought it should.

It is night and day after sharpening it though and the performance and edge keeping has jumped up markedly also. I did not change the bevel angle or reprofile it at all. I simply resharpened it up and can only figure like I've noted with many other blades I've used with factory edges that knocking off any remaining flaking or whatever from heat treat (and maybe the acid bath perhaps), did wonders for the edge.

I noted this on other steels in the past where after the first and second sharpening the results improved noticably. This one was no exception. Its seasoned now and a great user. I had it on me all day yesterday.

When you get time Thomas I'd like to get answers to my questions in email on the technique for removing the CF overscales. I've had some contacts from guys asking me about that.

STR
 
You're right, Thomas, that 154/13C26 looks boring. Actually, it looks like an ordinary Leek that someone took a gold Sharpie to! The composite Leek looks great, can't wait until February to get from Jay (Jilbert). Makes me kick myself even harder for not getting the Tyrade when I was down there( at the warehouse sale) :mad:, especially since Jay doesn't have it up here @ W&W.

Happy New Year to you Thomas, and Happy New Year to everyone on the forums. Thanks for your opinions, advice, and experience. They have served me well this past year in creating and forming this new addiction/passion we call knife colllecting.

Rik
 
This is what I mean.

On my opinion this line is boring just because it was drawn this way (it looks like a crack - exactly). If you try bit harder, I think it may turn out better even copper line will only be different.

My point - I see great potential in using it as a main decoration, but it should be good artist to make it right. I can only imagine what pro can do with this.

Thanks, Vassili.
 
:cool:...Vassili your examples are very nice. I do, however, agree with STR on this one. I also prefer the CPM D2/13C26 version in that bottom photo. The contrast is quite nice while not becoming garish to the point of becoming a "novelty" knife. I'll eagerly snatch one or two of these CPM D2/13C26's up when they are available. The counter-points and illustrations are great though Vassili...:thumbup:
