For the main [weapon manufacturers][1] in Borderlands 2, namely *Bandit*, *Dahl*, *Tediore*, *Jakobs*, *Maliwan*, and *Hyperion*, it's easy to tell how they affect weapons.  *Bandit* gives weapons bigger mags, *Dahl* has it's unique burst fire, *Tediore* has exploding reloads, *Jakobs* has a "fire as fast as you want" mode, *Maliwan* features increased elemental chance and damage, and *Hyperion* features a "more accurate as you fire" ability.

What I'm curious is to how these weapon manufacturers affect items like **shields**, **grenade mods**, and **artifacts**.  Is there a certain attribute that is tied with them to these items?
