What is the Hardness & HP of Double Weapons?

[Matt2VK]

How do you figure out the Hardness and HP of a Double Weapon?

Stuff like -
Double Walking Stick Katana
Double Chained Kama
Dwaven Urgosh
Gnome Hook hammer
Orc Double Axe
Two-Bladed Sword

To name a few.

What causes me problems is the enchanting & special material rules as
they treat each end as if it is a different weapon.

There is a table at the bottom.

Double Walking Stick Katana = Two-handed blade
Double Chained Kama = This is the only one I'm not sure on. To keep consistent, I'd go with Two-handed hafted weapon.
Dwaven Urgosh = Two-handed hafted weapon
Gnome Hook hammer = Two-handed hafted weapon
Orc Double Axe = Two-handed hafted weapon
Two-Bladed Sword = Two-handed blade

That table gives you a rough idea.

Now how do I figure it out if I make one end out of Adamantine and the other out of Cold Iron?

Both have a different type of hardness.

Roll a percentile for which half the person sunders unless they specify.

Just came across this FAQ

Adamantine: What's the hardness of a metal weapon made out of adamantine?

The answer depends on whether the weapon is entirely adamantine, or partly adamantine and partly some other material.

Table 7–12 on page 175 of the Core Rulebook lists common weapon hardness and hit points. The table assumes the weapon in question is made of leather, wood, and/or steel, as appropriate. According to Table 7–13, steel has hardness 10, which is why completely-steel weapons on the table have hardness 10.

Hafted weapon normally have a wooden haft rather than a metal haft. Even a steel-headed weapon such as a battleaxe has a wooden haft, so even though its head is made of a material with hardness 10, its weakest part is the haft, which has hardness 5, therefore the weapon is listed on Table 7–12 as having hardness 5 (because it is assumed that you're aiming at the weakest parts when trying to destroy an object).

For a weapon that is entirely made of one material (such as a one-handed blade), if that material isn't the standard material for that weapon, use that material's hardness from Table 7–13 instead of the default hardness on Table 7–12. For example, a wooden longsword has hardness 5, a glass longsword has hardness 1, and an adamantine longsword has hardness 20.

For a weapon that isn't entirely made of the same material (such as a wooden-hafted weapon with a metal head), if that material isn't the standard material for that weapon, use the hardness from Table 7–13 for the weakest material in the weapon instead of the default hardness on Table 7–12. For example, an ice-hafted (hardness 0) steel-headed (hardness 10) battleaxe has hardness 0 overall because it is only as strong as its weakest part. Likewise, an ice-hafted adamantine-headed battleaxe has hardness 0, just like its ice counterpart. ("Use the weakest material" is a relative term, as a battleaxe probably includes a small amount of leather, but its primary materials are wood and steel, so wood is its weakest material.)

Note that this "weak spot" of a hafted weapon doesn't affect the material properties of the weapon's head. A wooden-hafted adamantine-headed battleaxe still counts as adamantine for its attacks, is still of masterwork quality and has a +1 enhancement bonus to attack rolls, even if it is just as easy to sunder as a common steel battleaxe. The GM is also free to rule that damage to the weapon which only affected its head (such as dipping it into a shallow pool of acid) should use the head's hardness instead of the haft's hardness.

So the answer is, it still has the same hardness because the "heads" of the weapon aren't the wooden/metal haft of the weapon.
