I would never pay NIB prices for one. I had an opportunity to get a CQC-13 from a member on here for a great price, so I had to give it a shot. I was reluctant due to my past experience with a liner lock wearing out on a Commander model within like 2 months time. For the used price I got it for, it’s amazing. Deep and solid lock-up, but it hasn’t worn out over the few months I’ve had it. I’ve always love the design of the the 13, nothing else out there really like it. The only thing I would change would be to put the chisel edge on the other side. Also, I think they have about the best pocket clip design out there. I’ll keep my eyes out for a used CQC-7B. Probably the only tanto design I would want. I wouldn’t want to pay much over a $100 for it though.
