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.
