I'm surprised. I have 3 CQC models, a large, a small, and an auto, and all of them are sharp and hold the edge.
I also has Mark II and it sharp same as Microtech. Most important difference is that MOD has thickest edge on the market, while MT has thinest edge on the market. So MT cuts better and eazier to sharpen, MOD require more effort then average, but it got very sharp as well.
MOD and MT on my opinion are both build with performance first and price second, so both are pretty good made and have perfect quality. MOD I think pay mor attention to CQC and less to cutting perfection while MT more focused on cutting. IMHO MOD is bit more comfortable in use in many respect, not only CQC - but one follows another. Side bumps on guard is very usefull as well as fishlike handle shape.
I am not CQC expert but I read really good review, which stated that Mark is perfect for hand to hand fight and it's geometry allows utilithe more technicks then any other knife - it was Vietnamize specnaz vet review not a martial artist, I trust him in this regard (here it is in Russian -

). So if edge thickness not critical for this reasons. But I guess you need to be trained and experience fighter to utilize it's ability, for me it is just very comfortable in my hand.
So if you are looking for almost perfect cut and may appretiate it (may may not even notice) you should choose MT, if CQC important to you and you will be able to utilize Mark features you should get Mark I or II.
I wish I have MOD Mark II with MT edge on it...
Mark I and Mark II is two MOD knives I was talking about, I do not really may say too much about other models.
Thanks, Vassili.
