No one ever talks about dragon priest daggers! My ranger finally found a sibling for his (not counting the quest-oriented one), and now he dual wields them. They look pretty badass. They don't do much damage (dwarven level?) but they can be smithed (at least with the USKP).
They are rather unique in that you aren't likely to come across anyone else wielding them. I have added them to my Ranger character. He has evolved to where he mainly avoids combat other than to hunt, and all the rest of his fighting is done as a werewolf! However, for simple scuffles, these daggers are perfect.
