Vivi---That's 8° per side. I suspect that would make a weak general-purpose edge. What do you use such an edge for?
Oh you know, the usual....cutting PC power cables, chopping and batoning, and the ocassional food prep.

As you can see thin edges aren't that weak.
All kidding aside that knife is my true EDC and it does absolutely everything I would use a folding pocket knife for. I don't know the sharpening angle exactly, but if you'd like I can take a photo or video of me sharpening the secondary bevel to give you an idea of how close I hold it to my stone.
I'm still trying to figure out what people use 40-60 degree inclusive edges for on a small knife. That's thicker than my large choppers are.
