One Kershaw folder?

Composite JYDII, no doubt about it.

I haven't touched my Cyclone since my JYD arrived.
 
At last I decided....and I just recieved a Composite JYDII and a Speed Bump, I decided not to get the Cyclone...I'm very happy! Thanks to all who help me solve this dilema!
 
Good choices!

Now the only thing to consider is that Kershaw may discontinue the Cyclone. That would give you a nice knife from a collectible standpoint! :thumbup:

Kershaw: always messin' with your mind and wallet! :D
 
That's something to consider about...

Couple of questions: Wich is the HRc of the JYDII's D2 and the HRc of the Sandvick 12c26 used on the Bump Speed?, I couldn't find any info about it in the Kershaw homepage. By the way, Wich is the factory edge angle of the Speed Bump and the JYDII?
 
Not sure of the Rc, but the Speed Bump is Sandvik 13C26. I would imagine both knives follow Kershaw's MO and would be close to 40 degrees inclusive.
 
Thanks SPXTrader! It is always good to know the angles just in case, although I'm not planning using them by now.
I hope somebody could give us some info about the hardness of both steels...
 
I've never heard the Rc on the CPM-D2, but the numbers 57 to 59 keep popping in my head for the 13C26.
 
It seems like GG said somewhere around 58 on the CPM-D2 and 59-60
on the 13C26. I could be wrong. I also think GG mentioned the 14C28N
was going to run around 58, IIRC.
 
I looked at a speed bump and I got a spec bump. I like it much more than the speed bump. Black on black with the textured grips!! You will be happy!

DV, if ya wanna be technical, any layered blade is a composite, so it isnt exactly unique, more like 1200 year old technology.

Studlock is aptly named.

Im my experience (Im no metallurgist)....The CPM-D2 on my JYD and Leek seem to hold and edge and be harder to sharpen than the variety of 13C26 knives I own.

Perhaps. But I haven't seen a 1200 year old composite blade. Besides, the composite blade technology Kershaw is using isn't layered. Not on the new CB's anyway. :p
 
Ah, how well we twist words, you have my respect...Tony Soprano is just into Waste Management. True story.

I said that any layered blade was a composite, i.e. Damascus, or the katanas that blended not only different alloys but heat treatments...Kershaw has definitely been a ground breaker for using two alternating steels without fusing the two directly, but composite is composite, and layered or folded blades fit the bill.

Like I said, It seems like, and I could be wrong......So what's your point, other then "correcting" us??

Which seems to be a very fine service from you as of lately. :thumbup:
 
The question was posed which was harder, I just threw in my $0.2.

I wasn't trying to correct you, I was just posting what I have experienced. I know RC factors into hardness, wear resistance, and how brittle the blade is...but aside from that, Ive found that some knives rated at lower RC give me conflicting real world results from ones with higher ratings. Take the ATS-34 at 62RC and compare it to 154CM at 59RC, and you'll find them much the same in use.

I wasn't trying to put sand down your shorts...and Im just giving DV a hard time because he likes to mess with me too, then he emails me to tell me he's just playin...no harm intended to anyone, chill out.

I guess I need to go to sensitivity training again, sorry if you took that the wrong way.
