Thanks cerulean!
The serrated vs plain vs partially-serrated debate has been discussed a lot, and really there's no universal right answer. There's only the right answer FOR YOU! For someone else with different needs, their right answer could be different than yours. You might want to use the search function to look up the old debates.
For me, partially-serrated is my least favorite format, what I consider the worst-of-all-worlds. The biggest problem is that the chisel-ground serrations are out-of-line with the v-ground plain edge. So for jobs on which you wish you had a full 3.5" blade to cut with, instead you have an itty-bitty 2" plain edge next to an itty bitty 1.5" serrated edge. This happens to me often enough that I simply don't like partially-serrated at all.
Typically, I carry a plain edge blade, and I leave the edge coarse if I want serrated-type slicing ability. In the event I really do want a serrated knife (because I'm slicing something very hard, or because I want something that will go a long time between sharpenings), then I'd rather carry a fully-serrated blade specifically for that job. For me, in these cases the best answer is to carry two knives: my regular 4" plain blade, plus a 3" serrated delica.
