X3 on the Lansky system recommendation!!
I have a number of knives, including some Gerbers - Good solid workhorse knives, and affordable.
My latest and most favorite everyday work knife is the Kershaw Leek. It is a Speed Assist knife that opens in a flash with just one hand and has very good steel that comes sharp and stays that way a long time. Not the least expensive out there, but worth every penny IMO. Here'* a decent site that offers them for much less than regular retail.
As to the serrated issue, I have a couple I use if I'm going to be outdoors and need something more rugged for things like larger branch cutting or cutting tough animal tissue. Other than that, I prefer a plain blade for everything else. And yes, the serrated portions are more of a PITA to keep sharp.
