Text in rulebook:
The player must also declare which equipped weapon his hero is using. Heroes may either attack with one equipped weapon or their bare hands. A hero attacking with his bare hands can only target an adjacent space and rolls only the blue attack die for his attack. Only abilities on the chosen weapon may be used; if equipped with two weapons, abilities on the other weapon are ignored for the attack. If the hero wishes to make a Ranged attack, he must choose an equipped Ranged weapon.
Dual Strike:
Exhaust this card when you perform an attack, before dice are rolled. If you have 2 Melee weapons with 1 hand icon each equipped, add 1 surge to the results. You may use the surge abilities on both weapons during the attack.
If a skirmisher have 2 melee weapons with 1 hand icon each equipped:
1. Can he choose to attack with bare hands?
2. If he can choose to attack with bare hands, can he use a "Dual Strike"?
P.S. I apologize, I badly speak English.
