Not exactly my favorite wrench, but I have been impressed with what the “King” version of the Gator Grip socket can do on odd shapes.

Using a needle nose pliers you can repair these by carefully pulling out bent needle and straightening them, then reinserting.
Like the 10 mm “dime” shim example above,
the 36 mm viscous fan nut on Magnum V8s can be removed using an English wrench and a shim made from tin can stock.
Others just use an air impact chisel blade.
