When in civialian dress or garrison uniform I rotate between a Spyderco Police, Benchmade Stryker, and Spyderco Military. All are clipped in my strong side front pants pocket. All work reasonably well within my Manaois Eskrima training at my skill level. I also use a large varity of training blades in practice. I have trainers that match the size and shape of my carry knives and longer fixed blade trainers aso. I also regularly train with a large 15" bladed barong trainer and a 17" bolo trainer. In Iraq I rotated between a Gerber MK II, a CS SRK, and a CS Tanto attached to my IBA and Tactical Tailor MALICE Vest with the same folders clipped in my DCU pocket. I find a fixed blade of about 6" to 7" to work the best for me combativley. Here is a little secret, a lot of the FMA guys I know are really not that into knives and most dont even EDC a knife, at least in the states. In the PI its a different story.
