im level 76 i use the dawnbreaker and chillrend

or i use dual ebony war axes or daedric maces because war axes the ebony version looks kick ass and daedric maces are the most powerful one handed

If you use Daedric gauntlets as a khajiit and other accessories that up your attack, you can do up to 115 damage with one punch as long as you have the Fists of Steel perk.
