How do you get the best dagger in Skyrim?

Answer 1

You will find on corpses you defeat, or in chests or other places daggers. Sometimes people will be selling them too. As you go into the game further you will find more powerful ones. You can use a grindstone to make them more powerful, increase perks in one handed skill to give daggers more attack, or enchant them to give them abilities. If you wish, you can increase your blacksmitting perks so that you can craft with things like ebony or glass, and make a dagger from them which is very powerful.

Answer 2

Players can craft Dragonbone Daggers after leveling their Smithing skill all the way to 100 and acquiring the Dragon Armor perk. They will need one Dragon Bone and one Leather Strip to craft the dagger. Dragonbone Daggers are the strongest daggers in the game dealing base damage of 12, same as the Blade of Woe.
