I don't want to turn this into some Prac-Tac discussion, but I do want to let you know that from my own experience and "knife-fighting" knowledge, that slash techniques are not very effective when your target has clothing. No matter how sharp the knife is, it's going to be a difficult task to slice through jacket and shirt(etc) and then through flesh to cause a wound. Stabbing would be more effective, unless you were in control and could make the precise artery cuts.
Now, more OT, I would have to say that I would imagine the serrations would actually help in a SD situation. If you're talking SD, you're probably talking about your attacker being human which means hopefully that they will have clothing on. I could see the serrations tearing through the fabric, whereas the plain edge may just glance off. I'm a plain edge guy, but then again if I was using the knife for SD I wouldn't be wasting time with slashes so I wouldn't need the serrations anyways.
Either way, that's my opinion. Good luck, man. Glad to see someone else likes the 0400 too.
