2008 CRKT catalog

I do love that new M21SF, with G10 and Veff serrations. Looks like one of those ideal workhorse-type knives.
 
I want a Fulcrum now. Anybody know when these knives will be available and how much they are?
 
9cr18mov though? Isn't that just Chinese AUS8?

it's 440C..

The composition the catalog provides is that of 440C, but the proper name for 440C in this nomenclature would be 10Cr17Mo. Moreover, the Chinese alloy name indicates traces of Vanadium, but there is no Vanadium in either their stated composition or in 440C.

Benchmade stated that they had some problems with Chinese companies stating that they were providing an alloy with the composition of "440C" and not actually doing so.

I don't think this is really the same composition as 440C. There is likely a measureable difference in performance due to 440C having an extra .1%C and 1% less Cr.
 
Wow, that's a LOT of new offerings! I too like the turtle, will likely pick up a couple of those. There's a lot of other designs I like also. Regarding steels, AUS-8 is one of my favorite steels, so no prob for me there. And the 8Cr and 9Cr stuff seems pretty decent, especially for the prices that most CRKTs go for. Hmm, looking forward to seeing some of these in person at local shops to see how they feel.

Would that difference be limited to corrosion resistance?

I believe that was Spyderco, not Benchmade, Knarfeng. That is what caused Spyderco to drop the "440C" markings they were initially putting on the blades of their Byrd line of knives. They tested the steel, found that the properties weren't right, decided on a more accurate name for the steel, based on its properties, and stamped in on their blades.

Now that you mentioned Benchmade and 440C, don't you find it curious that, for several years running now, Benchmade has listed their 440C as having way less Carbon then any other steel chart does? Take a look: http://benchmade.com/images/table_blade_steels.gif

Isn't 440C supposed to have between .95-1.05 Carbon, not .75, like Benchmade's chart indicates?

I had a question about one of the blades that Benchmade currently offers in 440C. I queried Benchmade about their 440C via email. In their response, they said that they run across the problem of having Chinese 440C not meet the composition, even though the Chinese considered it 440C. They said that the 440C they currently use is actual 440C. The implication was that at one time it was not.

Add:
I found another typo in the Benchmade steel information. When I queried them about it, they admitted the error and changed it within a couple of days.
I had never noticed this discrepancy. Have you asked them about it?
 
It could be a typo, maybe they meant 440B?

I would think that could be a possibility, except, (a) they don't offer any blades in 440B (they do offer some in 440C), (b) they have been making the same "typo" for years now, despite the fact that their chart has been updated at least twice, as best I can tell, to include the two different Chinese steels, and (c) 440B is listed as having .75-.95 Carbon.

I see. Thanks, Knarfeng. I do, however, still find it curious that they now have listings in their steel chart for 8Cr14MoV, 9Cr13CoMoV, and 440C, but the 440C still shows .75 Carbon, which is way low for that steel. for 440A, which is .65-.75 Carbon, or even possibly 440B, which is .75-.95 Carbon, I could sort of understand it, but for 440C (.95-1.05 Carbon), I just don't get it!?!:confused:

I have found several errors in various steel composition charts on different company websites. It's easy to make such. Lots of alloys, lots of similar numbers.

When I do find an error, I notify the company. Some companies fix it. Some don't. Benchmade fixed the other error I found. Perhaps I will harrass them again.

Best,

Would that difference be limited to corrosion resistance?

Based on composition, I would expect true 440C to have better edge retension, though much depends on the heat treat.

I have a Benchmade mini-pika II. It has a similar Chinese steel 9cr13MoV. In manila rope cut testing, it performed slightly better than AUS8, but well below that of 440C. I would expect a similar result from this Chinese alloy.
 
me too, but 440C is better.:D

I went to the Benchmade website and used their Contact link. I asked about the composition of their 440C. In their response today, they said they use 440C in blades so marked and that the Carbon content on the table was a typo.
 
Those Lake 111 and Laredo folders look awesome! Especially the lock-closed feature! The Turtles look cool, too.

Wow. They needed to update that 440C on their chart for a couple of years now. I thought they were using a "Chinese" version of 440C that came with lower carbon. They might have to look over the steel chart a little more, I think there might be a few more errors.
