I love the CQC-7 design, it just works for me. The CQC-7 feels great in my hand, and the blade length is big enough without being too big. I carried a Benchmade CQC-7, then a EKI CQC-7B while in the Army & they worked great. My current favorite & EDC is the HD-7.
Now realize, the Emerson CQC-7 takes a bit of an adjustment from other knives. The chisel grind is a bit different to sharpen compared to traditional knives. Also Emerson uses 154 CM steel, so if you are a steel junky, you might not be happy.
That said, even though I can't get it as sharp as my traditional knives, I get it sharp enough. I also like 154 CM steel & got tired of all the steel hype. Most times the added cost of the newer steel was not worth the gain to me.
