Windscreen wiper blades (windsheild) have a metal part in them that once removed make stunning wrenches,
Follow where a street cleaner has been and you may find the odd steel bristle laying on the floor, check around curb stones and railings etc where you would imagine the bristle to be pulled out more, they also make quite good wrenches,
Some make shift ones have been made from the metal clips that are on pens or a bicycle spoke hammered flat at the end and bent over can be used, old eye glasses or head phone bands have also recently been reported as working well,
Personally if making them i would stick with the wiper inserts, you get 2 bits of metal per wiper and you will get around 3 from each insert i think,
Have a look around, if its metal, can be bent, is springy a little, safe to retrieve etc then you can probably use it, experiment.
