Ya, I'd have to agree with Alex C. The plain edge would be better unless you were cutting rope, cord, harness, seat belts and such, often. The plain edge can do it also, but the serrated edge would do it quicker. Personally I hate to sharpen serrated blades. And no, you cannot sharpen them on a standard wetstone. You could use a Spyderco Sharpmaker, or one of the many small crock sticks, or diamond rods specially made for a serrated blade (many options). The serrated edge gets dull just like the plain edge, but often times it appears sharper because it can often cut, when dull, due to the serrations.
