What's wrong with the CQC7-B:
Three things, it has a geometric edge shape, it is a liner-lock, and the handle is not as ergonomic as either the Raven or the Spec War.
I like the blade on the CQC7-A. I had a Raven E1-A, and it was a good blade. Geometric edges are just not as versatile and efficient as curved edges in my opinion.
Liner locks are just not the most reliable locks. They are good when they work, but too many of them don't. Some of the most consistently reliable liner locks I have owned have been on the Benchmade CQC7s though. I don't know if that is a function of the design or not.
The CQC7 purports to be the strongest, baddest little folder on the block, and I just don't think it gets the job done. The REKAT Pioneer is the strongest, baddest little production folder on the block, and I think second place might go to the updated Stryker. I won't talk about the Sebenza.
I can't rag too hard on the CQC7-B though. I happen to be packing a Benchmade 970 in my back pocket today. It has one of the most solid liner-locks I've ever owned, and I hand satin finished the blade myself. The attitude factor is very high. After all, versatility isn't everything. I've got a custom David Boye folder in my front pocket for that.
