I agree with Morgoth- I never buy serrated if I can help it. Unless you cut rope/netting all the time, a plain edge is more useful and easier to maintain.
Plain edges are good on anything!
I work retail, and all my use for knives is opening boxes, envelopes, cutting cardboard, and opening packages. Serrations don't offer me an advantage here. So I buy (and have never regretted) only plain edges.
Good luck!
