I think I've seen that Bark River puts a convex edge on held at 13 degrees. Pretty darn good for a factory knife company. I truthfully don't know what most of my knife angles are at. I thin them down every time I sharpen them until I start to see dammage. I also sharpen free hand so my edges are also a little convexed. It's very interesting to see how low people can take there edges compared to most of the factory knives, it's crazy. I think more people should try the thinner edges. Probably, I'm just guessing, 10 degrees per side may be a good general point for most steels.
