Any mods out there which add good looking lore friendly daggers? Preferably daggers which are big, like swords since I'm using them for my Orc.

Jaysus Swords adds a few realistic looking daggers and fighting knives, along with quite a few axes and swords. If you use it be sure to get the fixed version of the esp Sharlikan made or else just get kryptoper's Complete Crafting Overhaul Remade, which incorporates the necessary esp changes from Jaysus swords, so you don't need a separate esp for it, but you still need to install the assets (instructions for doing so are on the CCOR Nexus page).
