i have a 806D2 and a commander, and, personally, if i could have only one, would take the 806. of all my EKI stuff, the commander is the one i carry the least, dont get me wrong its ok, just not as good as a spec-war/SOCFK/waved CQC7 imho, i guess i like those tanto blades. and i like the AFCK handle vs the commander handle myself, imho the AFCK is one of the all time greats, a classic, ya can still get the AFCK 800 at
www.newgraham.com (i think) for like $70 or so, a great deal for a great knife.
the big plus for the commander is the wave, but ya can open the axis BM knives almost as fast and they prob are more sturdy than a liner, but have never had any lock probs w/EKI either, the wave is something else though, once ya try it you will like it i bet
but, overall i would prob take the 806, keep in mind the AFCK is one of my all time favs though, really fits my hand well, i'm sure others will disagreee w/me on this one, no 'dis' to ernie meant, the SOCFK IS my all time fac production knife!!
the grind is kinda funky, but once ya get used to sharpening them, ya can get them plenty sharp,, and bandityo rebeveled one of mine to a std 'v' grind, and its really sharp also, but the std one will also get plenty sharp too, just takes some getting used to, for me anyway.
