Before I saw the light(wave), I carried a Butch Vallotton SOF. Now, I carry a blact T Waved CQC-7 to and from work, then switch it inside my secure building for a Boker 3040 Ceremic utility. The Boker is perfect inside dress pants. Outside work, I augment the folder with a 4" bladed Cold Steel Safekeeper II push knife, which has been converted into single edge, bead blasted, and carried in a kydex neck sheath. If you study martial arts, push knives are a natural for pure defense. I'm waiting on a C/P I&I Tanto w/ wave to replace the CQC-7.
