One Hander

Trait One Hander
Benefit	+20% Damage when using One-hand weapons (40% for pistols).
Penalty	-15% to maximum chance to hit when using two-handed weapons.

Note: This trait DOES NOT work for Stackable weapon types such as Grenades and Throwing knifes

Note: If you have the Super Mutant class perk this works for two handed weapons AND has no penalty so its just a straight up 20% bonus to damage.
