Wonderful idea. I made one , and it works perfert. There's minor mod for it, and I thought it solve the Problem 2. Just use the unused part of the blade which's showed in the fisrt pic lower portion, make two ties on the wrench, both slideable, then the thing goes pefert. The tool still flexable, adjustable.
And I found the steel strip which is extracted from wiper blade has excellent cold bending performance. no need heat teatment and 2 pliers can make job perfect done.
sorry for the quality of pics. it's the best of palm Zire71's cam can do.
