Well, as per performance....I've actually bought 4 minigrips, one D2, one 154CM and two 440Cs. Weirdly, each steel was a different blade shape, and thus maybe the angles are different, which can affect performance a lot (drop point on the D2, leaf shape esque (whatever benchmade calls it) on the 154CM and tantos on the 440C).
Honestly, I wasn't impressed with the factory cutting dynamics of any of them. They were all a little beyond satisfactory, none were impressive. The 154CM had the best factory sharpness, but only by a little.
I gave the other three away after some time, and I only had the 154CM one for a few weeks, so I never really tested its edge retention. 440C had pretty good edge retention, but definitely needed some maintainence, but not so much it'd bother me. The D2 greatly outpaced the 440C and almost never needed to be sharpened, but that said, I never got it super sharp. The Tanto 440Cs did get really sharp after a pro sharpening. In a few weeks I'll get a report from the friend I gave the 154CM one to and see how it fairs (it's replacing his aging Storm).
I guess the problem I eventually ran into financially with the Cabela's version is that at 70ish dollars, you've got some nice options available to you. For 10 more, you could get an S30V, G10, AO Kershaw Avalanche that, other than the lock, will completely devour a minigrip. You could get a Spyderco Dodo for 70 with S30V and G10. Plenty of good alternatives that quite simply outclass the D2 minigrip.
The 154CM version is definitely more on par with the other ~50 dollar competitors.
If you want a D2 Benchmade mid sized folder, I'd honestly say save up and buy a 960. The cutting ability is superior, the F&F is superior, the looks are superior...it cost quite a bit more, and if you're looking for a beater, there's no reason to get it over the Cabela's, but if you want a long term EDC in D2, this is the one.
