if you don't first think..."why don't I keep them both".
dammit... my dog has diarrhea... he let it loose again... third time today.
But seriously, they are two completely different knives... Look and compare...

Blade Metals
154CM STAINLESS STEEL
USA made by Crucible Steel, which is now back in production. It was actually our original choice, but was not being produced at that time in rolled sheets conducive to our manufacturing, and was later discontinued by Crucible for lack of demand. Developed for use in military jet engine turbine blades, 154CM has properties approaching and surpassing some carbon steel blends. It's nearly identical in make-up as ATS-34. We're very excited to be introducing it into our blade production, and we process it the same as ATS-34 with equally superior performance results. (ATS-34 STAINLESS STEEL A high carbon alloy steel produced by Hitachi®with super-fine grain structure which bodes well for excellent lasting edgesharpness. We temper to a Benchmade "custom" toughness which has proven to offer higher than average blade strength.)
440C
(from BMF FAQ's by Joe Talmadge)
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
You see, not only are the knives of different metals, but they are of different sizes as well. Honestly, I think a few of the CRKT's offerings are superior to the Mini-Griptillian, while the Mel Pardue would be nice to own. I myself collect Benchmades and carry a Stryker every day, but I would certainly not feel ill-equipped if I carried, for example, a CRKT M-16.
