Ive had many different brands but have yet to pick up an emerson. I'm intrigued by the cqc7, cqc15, and cqc8. I figured it is time to break out the wallet. Has anyone had all 3? Which model seems to stand out the most of the 3? Which model performs the best in every day tasks? Which knife seems to carry the best? Im also open to serrations if they would benefit the knife's every day usage. Any suggestions and input would be great, thanks!
