One-handed governs your effectiveness when using one-handed weapons , including daggers, swords, maces, and war axes. With the addition of dual-wielding, one-handed weapons can be put in both hands in any combination. The higher your skill in One-handed, the more damage is done with one-handed weapons. The One-handed skill tree has a total of 10 perks, requiring a total of 21 perk points to fill. Each skill point grants a +% bonus to the damage dealt with one-handed weapons (+2% for NPCs). This bonus stacks with the ones provided by the Armsman perk and by Smithing -related improvements.
