edge retention of serrated vs straight : used carpet

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.
 
Ten degrees per side would be a solid place to start and just pick up any of the single bevel blades from Rangar's Forge for $5-$10. Just make sure to full regrind the edge before judging the edge holding and durability. Since they are so cheap you can use them fairly hard and thus get an idea of what that profile can and can't do.
