Contrary to popular belief, a partially serrated edge is NOT "the best of both worlds."
I dislike partially serrated edges. They reduce the useful length of the plain edge, and they tend to snag on the material being cut. Try the following experiment: cut a wide sheet of paper off of a roll, like butcher paper or gift wrap. Make sure there are no children or adults with sensitive ears present.
I hate partially serrated edges, but I hate them the most on blades that are already short to begin with, such as the Benchmade Leopard Cub, or the Spyderco Ladybug.
It is my considered opinion that a serrated edge is less versatile than a properly sharpened plain edge. Steve Harvey, who has a habit of being right about a lot of things, has said, "There is no cutting task for which a plain edge is a pain in the @$$ as a serrated edge can be."
I will admit that there are situations where serrations come in handy, as when cutting tough plastics. But there are a lot more situations where serrations are unnecessary and bothersome, so consequently I prefer to keep my serrations on a separate knife. I always carry more than one knife anyway, so this is not a problem for me. If I have to carry just one knife, it will always be plain edged.
The manufacturers and dealers will tell you that partially serrated edges sell better than plain edges on all models for which there is a choice. I believe this is because most people don't know how to sharpen a knife, and the serrated portion of the edge is likely to be marginally effective after the plain edge has become dull.
Have you read Joe Talmadge's FAQ on the subject of serrations? I recommend it.
There. I feel much better now.
