    ok, a few days ago i asked a few questions about the benchmade griptilian, now that i'm ready to order i was curious if i shoudl get the 440c one or opt for the newer 154cm bladed one

    would it be worth waiting for the 154cm blade? whats the difference between the two?

    thanks for all the help guys :bowdown:

    440 A - 440 B - 440C: The carbon content (and hardenability) of this stainless steel goes up in order from A (.75%) to B (.9%) to C (1.2%). 440C is an excellent, high-end stainless steel, usually hardened to around 56-58 Rc. All three resist rust well, with 440A being the most rust resistant, and 440C the least. The SOG Seal 2000 is 440A, and Randall uses 440B for their stainless knives. 440C is fairly ubiquitous, and is generally considered the penultimate general-use stainless (with ATS-34 being the ultimate). If your knife is marked with just "440", it is probably the less expensive 440A; if a manufacturer had used the more expensive 440C, he'd want to advertise that. The general feeling is that 440A (and similar steels, see below) is just good enough for everyday use, especially with a good heat treat (we've heard good reports on the heat treat of SOG's 440A blades, don't know who does the work for them). 440-B is a very solid performer and 440-C is excellent.


    ATS-34 - 154-CM: The hottest high-end stainless right now. 154-CM is the original American version, but for a long time was not manufactured to the high quality standards knifemakers expect, and so is not used often anymore. Late-breaking news is that high-quality 154-CM may again be available. ATS-34 is a Hitachi product that is very, very similar to 154-CM, and is the premier high quality stainless. Normally hardened to around 60 Rc, it holds an edge very well and is tough enough even at that high hardness. Not quite as rust resistant as the 400 series above. Many custom makers use ATS-34, and Spyderco (in their high-end knives) and Benchmade are among the production companies that use it.

    I'd go with the 154 :dunno:

    thats sort of my problem, wait few months and spend $10 bucks more for the 154cm, or hop on the 440c right now, although i would rather have the Doug Ritter RSK Mk1 model, but i cant bring myself to pay that much ($125) when i could get the other one for 65 ish

    I like how they say 154CM is the 'hottest high end' steel around, wouldn't that be more along the lines of s30V now? From what I've heard unless you're VERY hard on your knives I don't think you'll be able to tell a differance in the 2 steels. Although I really love my Ritter ;)

    BTW, not sure it it's still working, on knifeforums.com in the general discussion forum there was a coupon to buy the remaining Ritters from Aeromedix at the old price, worth a try.
