DAGGER

Item type DAGGER indicates a weapon usable by the THIEF class. However,
any player that has been a thief may use a DAGGER weapon, even once they
MULTICLASS into a different current class.

For example, if you are a current class cleric, but were a thief in a past
class, you will be able to use this weapon for combat.

The DAGGER flag does not mean that the weapon can be used to backstab.
The BACKSTABBER flag indicates that the weapon can be used to backstab.
