THis is rather common actually. Almost across the board, the serrations on a knife will be chisel ground.
A chisel grind, if you don't know (and even if you don't, you can surely guess by its name) will be flat on one side and only ground on the other, like this: |/. Every major manufacturer that I'm aware of does their serrations this way.
Usually, the rest of the edge is a normal grind, a V grind. This does vary though. Spyderco for example (the undisputed king of serrations) chisel grinds the serrations on their combo edges and V grinds the plain section. Their fully serrated blades are completely chisel grinds, while their plain edge blades are normal V grinds.
CRKT meets V grinds and chisel grinds halfway. There's still a V, but one side will be ground more than the other.
The reasons for doing this are a result of comprimise. Chisel grinds aren't terribly popular for plain edge knives because they're not as balanced. They're trickier to use for detailed work (since we're all used to more traditional V grinds), and when cutting, a chisel edge will have a tendancy to want to curve in one direction.
The problem is that serrations are almost always done with a chisel grind. Probably due to complexity of manufacter.
So we're left with 3 options for combo edge knives:
1. Fully chisel the entire edge, both serrations and plain edge (I believe Kershaws might be done in this manner, at least my old 2420 was).
2. Chisel grind the serrations, V grind the plain edge (Spyderco, Benchmade).
3. Go halfway like CRKT.
They all have their points and problems. A fully chisel ground edge, as said above, will have a tendancy pull to one side. With a chisel/V edge, you have 2 different planes where there's an edge, and your cut might not line up right or be as smooth. The CRKT halfway method, of course, is halfway.
So, in a nutshell, your knife is normal. If you get a Griptilian, the plain edge section will be a V grind, but the serrations will be chisel ground. AFAIK, the only manufacturer that doesn't make a serrated edge that isn't lopsided is Chris Reeve on the Sebenza, but even then, it's a staggered lopsided serration (ground on alternating sides).
