For anyone interested in using scripting to check for different combinations of one-handed weapons, here's how I do it. Opens up great options for providing bonuses for weird combinations of weapons or for fighting with an empty off-handed that the rather limited WeaponType checks can't accomplish.
First comes the laborious part: tagging every weapon root template with identifying tags. (I'm away from my main comp right now or I would just post the merged files. Reply if you want them and I'll get to it later.)
Next, with character- or game-scripts:
EVENT EquipWeapon
VARS
ITEM:_Weapon
ON
OnItemEquipped(__Me,_Weapon)
ACTIONS
IF "c1"
IsTagged(_Weapon,"1_DAGGER")
THEN
SetTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IF "c1"
IsTagged(_Weapon,"1HD")
THEN
SetTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IF "c1"
IsTagged(_Weapon,"1_WAND")
THEN
SetTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IF "c1"
IsTagged(_Weapon,"1_SHIELD")
THEN
SetTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IterateItemsInInventory(__Me,"FreehandCheckFor1HD","1HD_EQUIPPED")
EVENT FreahandHas1HD
ON
OnIterateCount("FreehandCheckFor1HD",1)
ACTIONS
SetTag(__Me,"ABST_AMBI")
EVENT FreahandHasO
ON
OnIterateCount("FreehandCheckFor1HD",0)
ACTIONS
ClearTag(__Me,"ABST_AMBI")
EVENT FreahandHasTwo
ON
OnIterateCount("FreehandCheckFor1HD",2)
ACTIONS
ClearTag(__Me,"ABST_AMBI")
EVENT UnEquipWeapon
VARS
ITEM:_Weapon
ON
OnItemUnequipped(__Me,_Weapon)
ACTIONS
IF "c1"
IsTagged(_Weapon,"1_DAGGER")
THEN
ClearTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IF "c1"
IsTagged(_Weapon,"1HD")
THEN
ClearTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IF "c1"
IsTagged(_Weapon,"1_WAND")
THEN
ClearTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IF "c1"
IsTagged(_Weapon,"1_SHIELD")
THEN
ClearTag(_Weapon,"1HD_EQUIPPED")
ENDIF
IterateItemsInInventory(__Me,"FreehandCheckFor1HD","1HD_EQUIPPED")
So this applies a tag if you only have one-handed weapon equipped, or a shield equipped and no weapon, and removes it if you unequip that weapon/shield or if you equip another weapon/shield.
If you change those initial tags to prompt other tags on equip (say 1_WAND would lead to WAND_EQUIPPED) you can combine this method with more convention checks for WeaponType to create simple checks for any kind of combination, i.e. a stance skill that only works if you have a Sword and Wand equipped, a talent that provides extra bonuses when wielding a Sword/Dagger, etc.
