I have been interested in a CQC7A for some time but have been reluctant to get one due to the comments about quality control issues at Emerson and the negative comments about the chisel grind blade. Please let me know your thoughts on this knife. The knife would be used primarily for general utility tasks and as a last resort defensive tool. Also, I notice that the part serrated version can be purchased from SMKW for $70. The cheapest that I have found the plain satin blade model is $86. Is the part serrated that much of a disadvantage to forego the cost savings? Thanks.
