The Kershaw virus is coursing quickly through my veins.

Can't get enough of those beautiful combination blades!

Keep it up Kershaw!
 
Very nice pic, boxant!:thumbup: Where the heck did you find that JYD II composite with no handle. I've never seen one before so it must be pretty rare.

Hold on to that baby for investment purposes!!!:D
 
I have and love the Tyrade and just picked up the JYD composite earlier today.

I'm also going to get a SG2 JDY and put the composite blade in the Ti framelock.

I was concerned it would not work but comparing them side by side the blade lock areas look the same. My knife guy agreed with me.
 
The D2 Leek is way up on my "want to buy" list. Only blade I own in D2 is a BM 730 Ares, and it has a killer sharp factory edge. I am very glad more makers are producing knives with tool and other forms of non-stainless steels.

I love the D2 Leek. The feel of having such a powerful edge on such a small/sleek knife is dead sexy.
 
The regular D2 used by other mainstream manufactures is a very different beast from this CPM D2 as used by Kershaw and Spyderco Military Ltd. This CPM D2 beast is said to take a keener cleaner edge and will take a harder by 1,2 point HrC temper while retaining the same toughness and at the same time is more stain resistant. So this CPM D2 is the real ants piss compared to regular D2.

The reason Kershaw makes the composite blade is because its prohibitively expensive to make the whole blade out of CPM D2. Besides the weld line makes for a very pretty blade while giving a cheeper price and hard edge with softer spine.

By the way, there is another variant called Friction Forged D2 which makes regular D2 behave like CPM D2.

Hey, thanks for the info! Good to know :D
 
Nice set BoxANT!:thumbup:

As kevtan mentioned, the old D2, sometimes referred to as wrought, is nothing like the newer CPM-D2. The latter will take a finer edge, as the carbides are physically smaller. Someone once compared them as denim to linen. One's tougher with bigger materials in the weave, while the other has finer materials. Both are very tough steels, but the CPM D-2 is a lot more rust resistant than D2.

CPM D-2 is right up there with SG2 and ZDP in my book!
 
That's great info on the D2, thanks! Now I'm really interested. My current all time favorite tool steel is M2, which I always preferred to standard D2. Sounds as though CPM D2 may compare favorably in its ability to take and hold a thin, keen edge, with the added ability to better resist rust and stains. Gotta check one of these out- sure seems as though the current crop of knifemakers (both custom and production) have become very skilled at separating man from money:D

Fairly high praise- if CPM D2 compares favorably with steels such as these, it makes the D2 Leek one of the best values on the market.

Both the Leek CB and the JYDII CB are incredible values.

I am waiting for the RAM CB to be added to that list! :D
 
ZDP-189 is still a monster compared to CPM D-2, and SG2 has a bit of an edge as well (both in alloy and hardness). However, CPM D-2 does have an excellent balance of toughness and edge holding. My best comparison would be with the old M-2 knives from Benchmade.

Don't mean to speak for SPX, but I think he was just saying that CPM-D2 is in the same group as ZDP-189 and SG2 because it has so many great qualities. I don't think he was saying that they are all the same, just that they are all great steels for their own individual characteristics.

I think it's great that we have several "super steels", each with their own "personality" that can be applied to different areas of need. ZDP will hold an edge FOREVER;), SG2 will whittle peach fuzz, and CPM-D2 will do a little bit of both!:D

Cheers,
Jon

Agreed.
I love the balance of properties in CPM D-2. It gives you a razor edge without putting up a fuss (easy to sharpen), and kicks up the toughness a notch higher than any stainless steel in it's class. For a medium-hard use knife I'd say it's just about ideal (perfect for the JYD II).
If someone would make a good knife in CPM M-4 that would take the cake (better edge holding), but since that hasn't happened yet CPM D-2 is the best we've got in my opinion.
