Judging from what's on display at REI and other outdoor shops, partially serrated blades are all the rage these days. I think that is a shame. In my opinion a reasonable quality, well maintained plain edge is the choice for general use.

About the only serrated edges I have are rescue knives attached to our PFDs for sea kayaking and other boating use. The idea there is an instantly available knife to quickly cut oneself free from entanglements. Other than that rather specialized use I refuse to buy serrated blades.
