I prefer half serrated knives, but also carry plain knives, and a fully serrated Spyderco.
When I lived in a rural area, it seemed like I was often cutting twine or rope. I even used my fully serrated Endura for cutting small PVC pipe in a pinch. I use a Spyderco Sharpmaker to sharpen serrated blades.
