I don't recommend going the smithing route, it's to overpowering even on master. It's an option though.
Or you can use conjuration, you need to be level 90 conjuration and have done the master quest, getting a sigil stone. Use the sigil stone with an ebony dagger, as well as a few other ingredients to make a daedric dagger at the atronach forge located under the college of winterhold. You can also make a random enchanted daedric weapon (you will need to reset to get a dagger) using some items.
The recipes are here - http://www.uesp.net/wiki/Skyrim:Atronach_Forge
Or you can find them at high levels, incredibly rare. Tonilia (thieves guild) will possibly sell one at high levels, you could keep resetting her shop until you get one.
