Damaging weapons. The table makes the distinction between a one-handed blade, a two-handed blade, light metal-hafted weapon, light hafted weapon, one-handed metal-hafted weapon, light hafted weapon, one-handed hafted weapon and two-handed hafted weapon.
A one-handed or two-handed blade is pretty obvious. But what's with all these hafted and metal-hafted weapons? What is a hafted weapon? What is a metal-hafted weapon? Why is there a one-handed metal-hafted weapon and no two-handed metal-hafted weapon? (well the previous questions probably answer the last question)
A hafted weapon attacked to a haft.
On a serious note a haft is essentially a long handle. An example of a hafted weapon would be the spear.
A metal0hafted would be one with a metal haft as opposed to a wooden haft.
I have no idea why there are no two-handed metal-hafted weapons.
HPM is basically right.
It probably helps to have some examples of each type:
One-handed hafted weapon: battle axe, short spear, flail, pick, war hammer.
Two-handed hafted weapon: spear, any pole arm, great axe.
One-handed metal hafted weapon: mace.
Basically, two-handed metal hafted weapons would be too heavy to wield effectively, and there aren't any historical examples that made it into the CRB (and considering how unwieldy a metal hafted spear would be, I'd be surprised if there any historical metal hafted two-handed weapons at all).
Yeah, there isn't a two-handed metal hafted weapon (AFAIK) because it would be unwieldly and heavy. I don't think there are historical examples of any, as you'd be talking about a 10ft metal pole with a blade of some sort of the end of it. HEAVY!
But yes, otherwise the distinction is wooden haft versus metal haft.
One could make an argument that any one-handed hafted weapon could have the haft made of metal or wood.
