In the ORB, on page42, it states that a model that is unarmed will be clearly specified that in its entry.
So, I believe that all models have ALWAYS had, unless stated, at least have a dagger. So, a Clansman always has a choice to blast away with his 2hd weapon or go in for a slice and dice using his/her dagger.
Fresh from the FAQ on the GW site (all have been updated Feb.2012)
Q: Some profiles imply that a warrior doesn’t have a
hand weapon – for example, those for Elf Warriors say
they have “no equipment” in their base profile. Does
that mean they’re unarmed? (var)
A: All models have a hand weapon unless they’re
specifically described as being “unarmed”. So Elf
Warriors do have hand weapons.
There ya go
