Oh, on the dirk/dagger thing...I poked around way back then and a couple of things came to light. First, the false edge is not sharpened and is designed to slip between joints and pry some space to cut through with the bottom edge. Second, the laws in most states are ambiguous, and often were designed for stiletto-type stabbing blades, not hunting edges with round tips.
Third, and most important, it is pretty much up to the discretion of the LEO in the situation to make the initial determination. The LEO's attention must first be drawn to the knife, and the KPH is not an attention getter, and the charge would--if made--be most like a "piling on" of different counts, done to create a more impressive case for the state's attorneys to decide to prosecute.
Have fun, be safe.
