A good serration doesn't act like a saw though. A good, sharp, serrated blade acts more like a bunch of hawkbills, one right after another. Serrations are supposed to cut, not tear. For me, they work really well on a small knife, since they give a lot more edge length without increasing the blade length. However, I prefer plain edges, mostly because I can't sharpen a serrated knife as easily. But still, try a good and sharp serrated edge! They cut a lot faster through cardboard and rope and such. They can even whittle a stick and such.
i love fully serrated blades, i think they are really cool, and ive found them to be fine for EDC. it depends on the model, but some knives just look best fully serrated, like the spyderco police as mentioned.
lately ive been carrying a full serrated Cold Steel Hold Out 2, and i love it. it looks so wicked. i used to EDC a full serrated spyderco military for a long time too and never had any problems with it.
Love em most of the time. unless they are on a survival knife. Can't sharpen/baton with them. But they are great on pocket knives. I can actually sharpen them easier than I can a straight edge. Full serrations I don't think would be ideal. But partial is great, especially out side work like land scaping.
