Only lens here without a UV filter is a 24mm Nikkor. And only because it vignettes the corners.

While in the retail business I made a pair of pliers into a "lens repair" tool. Two crescent shaped pieces of aluminum stock attached to the tips of the pliers, to straighten out the bent up threaded parts that came in the door. Never did it out in the open, it was leave the lens and we'll call you. That tool made money.
