IH, 2H, and 1H with shield are all separate skills, so if you put points into 1H, those won't help if you use a shield or a 2H weapon. Then you have to decide whether to develop slashing, piercing, crushing, shadow, or bone damage. Each of those is a separate skill tree. So if you like daggers, then you would use 1H piercing. The manual discusses this on page 43, Warrior Melee Specialties.
This seems overly complicated to me, however. I would have preferred it if the 1H skill applied to *all* damage types, although maybe 1H piercing could be a 4th specialty IMO. That way if you develop 1H, you would be just as effective with a bone or shadow weapon as a slashing weapon....but that is not the way it works... <img src="/ubbthreads/images/graemlins/disagree.gif" alt="" />
