Guyon,
A lot of people like partially serrated knives. Let me tell you why I don't. But first, let me say that I don't dislike serrations. I carry a serrated Endura every day along with one or more plain-edged knives. So please don't think my answer is a plain vs. serrated argument.
Okay, here goes.
According to my experience, the most useful parts of a "general use" blade are the extreme tip and the part of the edge nearest the handle. A partially serrated blade in the usual configuration, with the serrations near the handle, gives you a usable plain-edge tip for slitting open plastic bags, opening letters and that sort of thing. The drawback is that sometimes, quite often in fact, you will want the plain edge near the handle. For example, when whittling sticks (sharpening pencils), trimming fingernails, or cutting large sheets of paper off of a roll.
With a partially serrated edge I think you will often find yourself using either the plain portion or the serrated portion, which means a big knife like the Endura is really functioning like two tiny blades. You get tiny blade performance without tiny blade convenience or control.
Why give up half of a perfectly good blade? If you think you want the option of both plain and serrated, I recommend you get two Delicas, one plain and the other fully serrated, rather than a partially serrated Endura. This will give you several advantages: (1) you'll have a spare knife if you lose or break one; (2) you can carry one on both sides, for right and left hand accessibility; (3) the serrations will be there when you want them, and they won't be in the way when you don't.
As you know, I usually carry more than one knife, so I can have both plain and serrated. If I had to carry just one knife, it would be plain edged.
