I'm seriously considering a CQC 7A as my first Emerson knife. The question is which one? The full size is 4.65" folded while the mini is 4.25". The blade length on the full size is 3.3" and the mini is 2.9". I tend to carry smaller knives more frequently than larger ones just due to the convenience factor and the environment in which I work. However, the mini seems to be larger and heavier (3.75 oz) than other knives of similar blade length. The full size is only about 0.5 oz heavier and 0.4" longer. Which do you prefer? Which do you believe is handier and more useful for general cutting tasks and as a backup for self-defense. Thanks.
