Hereabouts all our wipers have a rigid plastic backing, no metal inserts. Material for picks is primarily hacksaw blades. HOWEVER! Have any of you considered going up to the street sweeper driver or ringing the business that is subcontracted by the city to do the sweeping and asking for some bristles? I did both and both times I got a handful of brand new unused bristles, in their v-shape, perfect, and for free! I explained honestly what I wanted them for, showed him ones I had already made, and the next time he went past my station he dropped off a handful. I offered to pay but he was happy to give them away.
It never hurts to ask, you never know, they just might say yes.
If it's stupid, and it works, then it's not stupid.
