I think the CQC-8 is a very good defensive folder. I carried custom and production 8's as a backup to firearms for a few years. The Super 8, minus the wave is perfect size for me, as I generally prefer larger folding knives. The design shares common ground with knives like the Benchmade AFCK and such, designed by/with input from military users who wanted/needed certain design requirements. Regarding the 4-inch blade on the regular 8, it's still one heck of a slasher/cutter. Most find the 4-inch blade just the right compromise in size, and still able to inflict a decent amount of damage.
